Fig. 6.7 Polynomial regressions of the estimated 24hour LC5o values for total ammonia nitrogen (TAN) as a function of the larval stage index of M. rosenbergii larvae fed either enriched or starved Artemia, demonstrating the difference in quality between the two cultures of larvae.

to alter the sex ratio in giant freshwater prawn, Baghel et al. (2004) bioencapsulated Artemia with different levels of alpha-methyl testosterone and fed these to prawn larvae for 50 days. Although not completely successful, a significant difference in sex ratios was obtained compared to the control group. However, the authors concluded that more research is needed with regard to doses and duration of treatments for complete hormonal control of sex differentiation in M. rosenbergii.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
