Starry flounder (Platichthys stellatus) is an important sport and food fish found around the margins of the North Pacific. Aquaculture production of this species in Korea has increased because of its commercial value. Microsatellite DNA markers are a useful DNA-based tool for monitoring the genetic variation of starry flounder populations. In this study, 12 polymorphic microsatellite DNA marker...

A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...

While two independent Chinook populations have been identified within WRIA 8 by the PSTRT, Marshall (2000) indicated that there might be enough difference between the North Lake Washington Chinook (Bear/Cottage Lake creeks) and fish returning to Issaquah Creek to consider them separate from one another. WRIA 8 would then contain three distinct Chinook populations (Cedar River, Bear/Cottage Lake...

Two facilities, Pahsimeroi Hatchery and Sawtooth Hatchery, operated by the Idaho Department of Fish and Game remain positive for Myxobolus cerebralis. Both facilities rely on river water supplies to complete rearing of ESA-listed Chinook salmon to the smolt stage prior to release. We have previously reported the seasonal pattern of infectivity to rainbow trout sentinels exposed to these waters....

“Fishery-photovoltaic (PV) Integration” is a novel aquaculture model that provides enormous potential for development. However, research on the environment and organisms under “Fishery-PV mode presently sparse. This study investigated Penaeus monodon as model, studying growth rates of shrimp, water quality conditions, micro-ecological environment. After 105 days rearing, P. (initial weight 0.00...

The widespread use of antibiotics in veterinary practice and aquaculture has led to the increase of antimicrobial resistance in food-borne pathogens that may be transferred to humans. Global concern is reflected in the regulations from different agencies that have set maximum permitted residue limits on antibiotics in different food matrices of animal origin. Sensitive and selective methods are...

The endangered Rio Grande silvery minnow persists as a remnant population in a highly fragmented and regulated arid-land river system. The species is subject to dramatic annual fluctuations in density. Since 2003, the wild population has been supplemented by hatchery-reared fish. We report on a 12-year (1999-2010) monitoring study of genetic diversity and effective population size (N(e)) of wil...

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...
