A highly sensitive and specific TaqMan real-time PCR was used to quantify hepatopancreatic parvovirus (HPV) type III infections in wild broodstocks and hatchery-reared postlarvae (PL) of Fenneropenaeus chinensis. Totals of 159 and 162 wild brooders from three locations were captured, and 140 and 180 PL were obtained from seven and six commercial hatcheries in 2007 and 2008, respectively. Among ...

As a first step toward the genetic mapping of QTL affecting stress response variation in rainbow trout, we performed complex segregation analyses (CSA) fitting mixed inheritance models of plasma cortisol by using Bayesian methods in large full-sib families of rainbow trout. To date, no studies have been conducted to determine the mode of inheritance of stress response as measured by plasma cort...

In order to develop a sustainable salmonid aquaculture, it is essential continue reduce the use of protein-rich fishmeal. One promising solution do so plant-derived carbohydrates in diet destined broodstock. However, mammals, reduction protein content (replaced by carbohydrates) parental known have strong adverse effects on offspring phenotypes and metabolism. For first time, effect paternal ma...

Selective programs associated with domestication can improve fish production but also have an impact on broodstock’s genetic diversity. In this study, the diversity of original sources (G0) from wild and cultured bighead catfish populations, as well two successive generations (G1 G2) subjected to selection experiments, was assessed. G0 adults were collected in Ca Mau conservation area a hatcher...

This research aimed to evaluate the reproductive potential of hatchery-reared (F1) pike-perch (Sander lucioperca) broodstock fed a commercial diet with low levels long-chain polyunsaturated fatty acids (Lc-PUFA) and wild (F0) forage fish. Reproductive parameters, including pseudogonadosomatic index (PGSI), egg size, latency time, hatching rate, embryo survival, eggs’ acid (FA) composition, as w...

The black rockfish, Sebastes inermis (Sebastidae), is an important commercial fishery resource in Korea. As a preliminary investigation into the effect of artificial reproduction in a hatchery facility, the genetic divergence between parent and offspring populations of black rockfish was accessed using 10 polymorphic nuclear microsatellite DNA loci and a mitochondrial (mt) control gene. All loc...
