Aquaculture and fisheries biotechnology. Genetic approaches by Rex A. Dunham

By Rex A. Dunham

The genetic development of fish for aquaculture and comparable fisheries is a box of study that has noticeable huge advances in recent times. but there was no ebook which supplies an available evaluate of the topic in the past. The booklet fills this hole within the literature. The contents contain polyploidy, sex-reversal and breeding, gene mapping and advertisement functions.

Aquaculture: An Introductory Text

There at the moment are many introductory classes in aquaculture given at schools and universities, yet there's a loss of applicable basic textbooks for such classes. This ebook goals to fill this hole by way of delivering a large and readable review of the topic. the focal point is on aquatic animal construction, commonly of finfish and shellfish, yet aquatic crops also are pointed out.

Atlantic Salmon Ecology

The Atlantic salmon is among the such a lot prized and exploited species world wide, being on the centre of a huge activities fishing and more and more because the significant farmed species in lots of international locations around the globe. Atlantic Salmon Ecology is a landmark e-book, either scientifically very important and visually appealing.

Ecology of Harmful Algae

Damaging algal blooms are one of many effects of the human impression on aquatic ecosystems, fairly the method of eutrophication. they could reason quite a few deleterious results, together with the poisoning of fish and shellfish, habitat disruptions for plenty of organisms, water discolouration, seashore fouling, or even poisonous results for people.

Paternal effects were important before the eyed stage, while maternal effects predominated at hatching time and during the early life of the alevins (Blanc and Poisson, 1988). Guo et al. (1989) found that the growth of triploid rainbow trout was affected by maternal strain. Triploid Nile tilapia grew 66–90% faster than diploids and had decreased sexual dimorphism for body weight; yet other studies indicate no growth advantage of triploid Nile tilapia. Strain effects or genotype–environment interactions are possible explanations for these discrepancies.

Triploid Atlantic salmon female ϫ brown trout, Salmo trutta, females grew at the same rate as Atlantic salmon in saltwater net pens (Galbreath and Thorgaard, 1997). Gilthead sea bream, Sparus aurata, eggs ϫ P. , 1995) had no growth superiority compared with either parent up to age 2 and 3 years. , 2000). After 3 years, the growth differences remained but were small. Sexual maturation resulted in males of all genotypes being smaller than females. When female grass carp, Ctenopharyngodon idella, were hybridized with male bighead carp, H.
