Aquaculture and Fisheries Biotechnology, CABI Publishing by Rex A. Dunham

By Rex A. Dunham

The genetic development of fish for aquaculture and similar fisheries is a box of study that has visible massive advances in recent times. but there's no publication which gives an obtainable evaluation of the topic. This ebook goals to fill this hole and should be compatible for complex scholars and researchers in animal genetics, fish biology and aquaculture.

Example text

Genotype–environment interactions are common for triploid fish. Triploid production has great potential to enhance performance in fish and shellfish; however, many problems exist. The first is that triploids can sometimes be fertile, defeating the advantages of sterility. Polyploidy can decrease performance for some traits. For many species, polyploid production may not be economically feasible. A. Dunham 2004. A. Dunham) Polyploidy 1984; Lou and Purdom, 1984). 1). Ueda et al. (1988) were able to induce triploidy in rainbow trout by applying high pH and high calcium to either sperm or eggs.

1998; Soether and Jobling, 1999), but others suggest that the compensatory gain is limited in fish (Gaylord and Gatlin, 2000). This phenomenon is of great interest as it has several applications in aquaculture. Some farmers believe that stunted fingerlings exhibit extraordinary growth and compensatory gain and prefer them for stocking in grow-out ponds. If compensatory gain were to exist in fish, it would negate the validity of multiple rearing to produce fish of similar size for initiation of growth comparisons.

It has been suggested that the mechanical induction of triploidy could have enduring adverse effects on the survival and growth of triploids. However, Blanc et al. (1987) found that triploids produced from shocks had the same growth and performance as triploids naturally produced by mating diploid rainbow trout females with tetraploid males. , 1986a). This slight difference in growth could be a result of increased heterozygosity in the naturally produced triploids compared with the mechanically produced triploids, rather than any effects from the induction procedure.
