An Introduction To Aquaculture

The best argument for aquaculture is based on the ever-increasing need for protein foods. Fish and aquatic invertebrates are efficient food i converters, capable ot producing more protein ) per unit area from the same amount of food than their warm-blooded counterparts. The quality of protein is the highest available from animals and is the lowest in fat content.

The genus Macrobrachium in aquaculture

All the freshwater prawns that have been used in aquaculture and associated experiments belong to the genus Macrobrachium Bate, 1868. This is the largest genus of the family Palaemonidae Rafinesque, 1815 (superfamily Palae-monoidea Rafinesque, 1815 infra-order Caridea Dana, 1852 order Decapoda Latreille, 1803 sub-order Pleocye-mata Burkenroad, 1963), and about 230 species have been described so far (C. Fransen & S. De Grave, pers. comm. 2008). Almost all of them live in freshwater, at least for part of their life. The genus is circumtropical and native to all continents, except Europe and Antarctica. A number of Macrobrachium species have been used for aquaculture experimental work M. acanthurus (Wiegmann, 1836), indigenous to Atlantic America North Carolina to South Brazil M. amazonicum (Heller, 1862), indigenous to Atlantic South America Venezuela to South Brazil M. americanum Bate, 1868, indigenous to Pacific America Baja California to North Peru M. carcinus (Linnaeus, 1758),...

The transformation of agriculture

Economic growth, urbanization, and the withdrawal of labor from the agricultural sector lead to the increasing commercialization of agricultural systems. Commercialization, in turn, leads to greater market orientation of farm production, progressive substitution of nontraded inputs in favor of purchased inputs, and the gradual decline of integrated farming systems and their replacement by specialized enterprises for crop, livestock, poultry, and aquaculture products (Pingali, 1997). Agricultural output and input use decisions are increasingly guided by the market and are based on the principles of profit maximization. This, in turn, influences patterns of crop genetic diversity through changes in land-use patterns and through crop choice changes.

International Agricultural Research Centers

Livestock Research Institute (ILRI), and International Service for National Agricultural Research (ISNAR). The Center for International Forestry Research also uses biotechnology in the characterization of forest diversity in its Asian program. The International Center for Living Aquatic Resources Management is using new technologies in the improvement of fisheries and aquaculture systems. ILRI is initiating a program on Asian livestock improvement. The CGIAR centers invest approximately 30 million per year in modern biotechnology. Further details of the way the IARCs use biotechnology in their crop improvement programs are given in Appendix 11.

Recirculating dosed system

In general, recirculating systems are believed to be the best systems for M. rosenbergii hatcheries. They operate at low cost, save water, have less environmental impact and provide higher productivity. A comprehensive and useful text covering all aspects of recirculating systems in aquaculture is provided in Timmons et al. (2002).

Checking and staging larvae

This method has been successfully used in the analysis of commercial hatcheries in Thailand, Malaysia and the Philippines to highlight problems in management (M. Tayamen, pers. comm. 1999). Using this method, larvae scoring high on this system have been demonstrated to show better growth and survival (M. Tayamen, pers. comm. 1999). However, in the experience on one of the authors of this chapter in the Aquaculture Centre, Sao Paulo State University, Brazil, poor survival was obtained in tanks that showed a high condition score during the whole culture period therefore this assessment method should be used with caution.

The range of applications for cysts originating from these alternative sources is mostly analogous to the GSL strain, which is unofficially considered as a 'standard' in aquaculture practices. However, since these new species are dominated by a variety of parthenogenetic populations they often display characteristics that deviate markedly from GSL cysts, which affect suppliers and customers. These characteristics include diapause features, chorion colour, cyst and naupliar biometrics, nutritional (HUFA) profile, buoyancy, decapsulation requirement and behaviour, hatching percentage and hatching rate, separation of instar I nauplii in hatching vessel, enrichment requirements, etc. This applies also to several Artemia sources with only local or regional commercial importance, such as A. sinica from several lakes in continental China and adjacent territories, and A. urmi-ana from Lake Urmia, Iran. higher need for cysts. Currently, the biggest demand is for penaeidshrimp hatcheries (>...

Wagner C Valenti Michael B New KR Salin and Jinyun Ye

Freshwater prawn monoculture may be extensive, semiintensive or intensive. These systems differ according to the farm plan and the level of farmer intervention in the production process. According to the intensity of the system, productivity may range from below 0.5t ha yr to more than 5 t ha yr. Wickins & Lee (2002) discussed the grow-out of crustaceans cultured in tropical climates at various levels of intensity and categorised the systems as extensive, semi-intensive, intensive and super-intensive. Although the words extensive, semi-intensive and intensive are frequently used in aquaculture, the meaning of these terms has been much confused, mainly because intensity categories cannot be defined precisely. Valenti (1998a) standardised each level of intensity for freshwater prawn culture, as described below. Most aquaculture technicians consider the management of semi-intensive ponds very simple and fail to explore its full potential. However, this form of culture exhibits a high...

Origins of modern freshwater prawn culture

Freshwater prawns have been reared in captivity, either through introducing wild-caught juveniles or by trapping them, along with other crustaceans (e.g. Penaeus spp. and Metapenaeus spp.) and fish, in tidal ponds and paddy fields, for example in the Indian sub-continent and Malaysia (Wickins 1976), from time immemorial. However, modern aquaculture of this species has its origins in the early 1960s. Ling & Costello (1979) and Ling (1977) recalled that experiments on the rearing of prawn larvae had been conducted by fisheries biologists all over the world but had been unsuccessful before then. In 1961 the first major milestone was achieved at the Marine Fisheries Research Institute in Penang, Malaysia, when the Food and Agriculture Organization (FAO) expert Shao-Wen Ling (Fig. 1.1) discovered that freshwater prawn (M. rosenbergii) larvae required brackish conditions for survival. Dr Ling's poignant description of his first experiments (Ling 1977), which included his observations...

Rural development statistics

The overview given in this section is far from exhaustive. In general, however, it reflects the main agricultural statistics in the UNECE region. Smaller data collections on endangered species, home farming and ornamental aquaculture - which might be useful in a full description of the situation in a specific country - have not been included.

Land Treatment Systems

There are two major categories of reuse of wastewater, which have been practiced throughout the world potable use and nonpotable use. The potable use of wastewater mainly includes injecting reclaimed water to the drinking water supply after multiple levels of treatments, or using natural systems (including land applications) to treat wastewater directly. Nonpotable uses of wastewater are many direct irrigation of agriculture fields using food wastewater with low BOD5 and TSS irrigation of parks, forests, or golf courses with low-load wastewater and use for aquaculture are the most promising examples. In many areas of the world, wastewater reuse has been practiced using a combination of treatment technologies that achieve a very high degree of treatment. Many states in the western U.S. have, over the past 20 years, been treating wastewater to tertiary treatment standards and then allowing the wastewater to be reused for irrigation or for recharge to groundwater aquifers. Although this...

National Center for Genetic Engineering and Biotechnology

BIOTEC is dedicated to the principle that the players in the shrimp industry should take an active role in planning and financing R& D for their industry. BIOTEC actively promoted the formation in 1996 of an industry consortium, the Shrimp Culture Research and Development Company, dedicated to solving problems common to the shrimp aquaculture industry as a whole. This consortium serves the industry directly and also serves as a bridge to other public and private institutions involved in relevant research, not only in Thailand but throughout the world.

Freshwater Prawns In Myanmar

This alone was a significant development within Thai aquaculture. However, this project also generated However, 'Giant Prawn 1980' was probably more influential in stimulating further global research and development, commercial farming, and personal contacts in this field than any other conference. With the aid of the FAO project on the expansion of freshwater prawn farming, the Thai Department of Fisheries hosted this meeting, the first international aquaculture conference ever held in Thailand (New 1982). One hundred and fifty-nine participants attended from thirty-three countries, and a further two hundred local farmers participated in a special session in the Thai language. One of the two original Macrobrachium pioneers, Takuji Fujimura, by then working in Hong Kong, was an active chairman of the discussions on practical prawn farming. The other, Shao-Wen Ling, though unable to attend personally, sent a welcoming address. 'Giant Prawn 1980' was convened by the author of this...

Emerging Zoonotic Agents of Concern in Agriculture

Throughout the world, we are seeing unprecedented changes in our economic, social, and ecological systems that are having adverse impacts on plants, animals, and humans. These changes are leading to the resurgence of old diseases and the emergence of new ones. The landscape and diversity of animals in many regions are changing due to overgrazing and deforestation. Increasing pollution of water bodies by nitrogen-rich waste-water, fertilizers, and soil runoff and loss of wetlands and mangroves due to development and aquaculture, diking, and drilling is promoting growth of marine and freshwater algal blooms. These algal blooms may be toxic to animals and humans. Monitoring the patterns of temperature, wind, precipitation, and biodiversity has enormous implications for surveillance of disease vectors and reservoirs (1).

Desalination of Sea Water

Saline, brackish and fresh water all will have their unique ecological pathways. Aquaculture, the farming of aquatic organisms, will be integral to the restoration process. The abundant organic wastes produced by shellfish and fish will be used to help build soils. Cultured fishes and shellfish will provide an early economic base for the enterprise.

Agriculture and Allied Areas

With an extensive coastline, India has great potential for marine resource development and aquaculture. Scientific aquaculture offers real opportunities to achieve an annual target production of 10 million metric tonnes of fish. Aquaculture products are among the fastest-moving commodities in the world, so we have to continuously improve seed production, feed, health products, cryopreservation methods, genetic studies and related environmental factors. Aquaculture will help substantially in the diversification of the bread basket and in combating nutritional deficiency.

Future Challenges

(ii) reducing chemical inputs of fertilizers and pesticides and replacing them with biologically-based products (iii) integrating soil, water, and nutrient management (iv) improving the nutrition and productivity of livestock and controlling livestock diseases (v) achieving sustainable increases in fisheries and aquaculture production and (vi) increasing trade and competitiveness in global markets.

Acknowledgements

Our thanks also go to the many friends and colleagues who provided essential and previously unpublished information for Chapter 17 (see below). Additional aquaculture colleagues and friends assisted us with other chapters ofthe book in many ways. Last but not least, we wish to thank the staff of our publishers, whose co-operation brought all our efforts to fruition.

Fisheries statistics

The programme of fisheries statistics in the EU provides statistical information on fisheries needed for the management of the Common Fisheries Policy. The programme comprises the following elements catch statistics, landing statistics, aquaculture production statistics, supply balance sheets for fisheries products, fishing fleet statistics, employment statistics, socio-economic data, and structural and sustainability indicators. The programme of work is designed primarily to provide statistical support for the management of the Common Fisheries Policy and to meet the EU's commitments to international bodies of which the EU is a contracting party. Apart from meeting numerous ad hoc requests for data from EU institutions, national and international organizations, and public and private organizations and individuals, Eurostat meets routine requests for data from the FAO fishing fleet statistics, thereby removing the obligation of EU member states, the Northwest Atlantic Fisheries...

Present Problems

In Asia, private sector investments in the rural sector and related R& D have concentrated on export commodities. The downward trends in public investments by governments and development agencies in smallholder agriculture over the past decade have not been matched by a concomitant rise in private investments. Similarly, there is little (and few incentives for) private R& D on the food crops, livestock, fisheries, and aquaculture systems important for food security and poverty reduction in rural Asia.

Fisheries

CRIF (AARD) administers research institutes for marine fisheries, freshwater fisheries and coastal aquaculture. In the Research Institute for Coastal Aquaculture, research covers development of feeding materials for shrimp and fish improved genetic stock disease diagnosis production of enzymes, such as protease, from fish waste use of proteases to descale fish and fish preservation through drying and salting. Production of proteases by Bacillus stearothermophilus is being investigated at RIAP. Indonesia has great potential to expand fresh and coastal fisheries and shrimp production.

Further developments

Research on recirculation systems has paid off and is being translated into commercial practice. Due to the need to develop sustainable aquaculture techniques that conserve vital water supplies and minimise effluent discharge, these methods are likely to be increasingly applied in the future. Chinese papers on M. rosenbergii research are rapidly expanding but usually appear only in Chinese agricultural journals and fisheries magazines. Some ofthese papers refer to topics relevant to this chapter but provide only a title or an extremely brief abstract in English, so it is impossible to include information from them here. It is to be hoped that such research results will soon become available to a wider audience through publication, in English, in international aquaculture journals. Since China is now the major producer of farmed freshwater prawns (Chapters 1 and 17) it is certain that it has much to contribute to our scientific understanding of hatchery systems and management.

Leptospirosis

Leptospirosis does occur in the poikilothermic vertebrates, as evidenced by positive serological reactions and by the isolation of pathogenic leptospiral serovars. The finding of leptospirosis species in fish, mollosks and other aquatic species are of special importance in view of the increased worldwide interest in aquaculture farming. Since 1975, 24 of the 101 (23.7 ) reported human cases of leptospirosis in Hawaii have been associated with aquaculture industries (taro farms, prawn farms and watercress farms) (39).

Results

However, when addressing the identified offshore stakeholders, most of the interviewees were generally interested in this specific type of multiple-use setting and vitalized the conversation around the guiding questions with their own comments and ideas. Concurrently with judging 'wind farm - mariculture integration' as an idea worthy to consider, interviewees mentioned several framework requirements for initiating and effectively pursuing cross-sectoral offshore operation and organisation. Not only had certain preconditions to be fulfilled, for example the need to clarify the working tasks and siting of aquaculture installations in the forehand, but also overall regulatory conditions, e.g. determination of working rules, allocation of responsibilities, as well as commercial arrangements or actuarial regulations (Figure 1). The issue of sharing responsibilities in the context of everyday organisation and questions of ownership were especially stressed. In the following, we discuss the...

Stabilization Ponds

Sewage Treatment Tile Field Depth Design

One of the ancient wastewater treatment technologies, the stabilization pond (also referred to as a lagoon), has been used continuously as a method of sewage disposal. In some cases, these ponds were also utilized for aquaculture. Stabilization ponds are used for both municipal waste-water treatment and industrial wastewater treatment, particularly for wastewaters from small communities and seasonal industrial wastewaters as well as less affluent communities throughout the world (Fig. 6.1). Although stabilization ponds can be used in most regions of human habitation, their performances in treating wastes are at best in warm climates with adequate sunlight. The current interest in waste stabilization ponds (WSPs) is a result of the accidental discovery of their capabilities when WSPs were used initially as simple sedimentation basins or emergence holding ponds at wastewater treatment plants. A WSP is a relatively shallow body of wastewater contained in an earthen man-made basin into...

Cyst market

At the 1976 Food and Agriculture Organization (FAO) Technical Conference on Aquaculture in Kyoto (Japan), Sorgeloos (1979) launched the idea that the cyst shortage was a temporary problem and could be overcome by the exploration and development of new Artemia resources and by the application of improved methods for cyst processing and use. By 1980 the situation had improved, with several new commercial products from natural (e.g. Argentina, Australia, Canada, China, Colombia, France) and man-managed (e.g. Brazil, Thailand) Artemia production sites. However, cyst quality in terms of hatching rate and nutritional composition proved to be highly variable, not only among the various strains and species of Artemia, but also among various batches from the same location (Leger et al. 1986). During the 1980s, new methods for evaluating and manipulating the hatchability of cysts and the

Fish Farming

Despite a long history of reliance on fish as an important source of food, oQ'Z particularly protein, the science of aquaculture is relatively young. Thus, our understanding of genetics, breeding, and reproduction in fish lags behind other agricultural sciences. Tremendous potential exists, however, to use modern ra.l technologies, including biotechnologies, to improve aquaculture. One advantage to working with fish is that, in most cases, each fertilization and subsequent goj development can easily be manipulated. It is possible, for instance, to manipulate the number of chromosome sets in fish eggs to get triploid and E< P tetraploid fish. This technique produces sterile progeny, which helps ensure 2j ra maximum growth because no energy is wasted on reproduction. Scientists can also regulate the sex of fish through various treatments, an advantage because S J female fish are preferred for commercial markets. io-l proven effective in promoting fish growth, and genetic engineering...

Fish Borne Diseases

Fish farming, or aquaculture, for fish and shellfish is becoming more common and more internationalized with every passing year. In the United States, more than half the seafood consumption is imported, much of it from fish farming. The world's seafood trade is very complex, and if is often difficult or impossible to determine where the seafood is raised or harvested. For example, the United States imports salmon from Switzerland and Panama though neither country is known for large salmon fisheries (36). In general, farmed fish is as safe and nutritious as wild-caught species, but there are public health hazards associated with ignorance, abuse, and neglect of aquaculture technology. Numerous small fish ponds increase the shoreline of ponds causing higher densities of mosquito larvae and cercaria, which can increase the incidence and prevalence of lymphatic filariasis and schistoso-miasis. Especially dangerous is the use of human waste draining to fertilize or create ponds. Technology...
