On the reproductive success of early-generation hatchery fish in the wild
Large numbers of hatchery salmon spawn in wild populations each year. Hatchery fish with multiple generations of hatchery ancestry often have heritably lower reproductive success than wild fish and may reduce the fitness of an entire population. Whether this reduced fitness also occurs for hatchery fish created with local- and predominantly wild-origin parents remains controversial. Here, we re...
متن کاملApplication of microsatellite DNA method in determining genetic diversity of farmed broodstocks of Penaeus vannamei (Boone, 1931) in hatchery centers of Bushehr province
The aim of this study was to detect different populations of Pacific White Shrimp (Penaeus vannamei: Boone, 1931) in farmed broodstocks and to determine their genetics indeces in hatchery centers of Bushehr province. First, the origin of the farmed broodstocks was determined based on the historical information of the different stocks. Then, DNA was extracted from muscle tissue of 30 broodstocks...
متن کاملEconomic evaluation of hatchery solid litter processing as poultry feedstuff supplement in Iran
The purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. The data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR) methods were applied for this analysis. In the studi...
متن کاملProductivity, biochemical composition and biofiltering performance of agarophytic seaweed, Gelidium elegans (Red algae) grown in shrimp hatchery effluents in Malaysia
Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration in aquaculture waste. In this study, the agarophyte Gelidium elegans originating from Korea was investigated for bioremediation of tiger shrimp (Penaeus monodon) broodstock effluent (SBE) in a shrimp hatch...
