Field trials were conducted to assess the potential for stocking native unionid mussels in urban streams of Chesapeake Bay catchment. Juvenile, hatchery-raised placed enclosures at five (two restored and three unrestored) two nearby rural streams. Adult translocated Mussel growth survivorship assessed stream sites individuals maintained hatchery ponds. At all sites, water quality conditions gen...

Aceh Besar Regency has a relatively large freshwater fishery area. Based on the 2019 BPS, it was recorded that area of aquaculture in Jantho at BBI 32.10 Ha, while People's Breeding Unit (UPR) had an 15.60 Ha. produces fish, namely catfish, gourami, carp, and tilapia. However, every year there is significant increase production, tilapia with percentage production 17%. This occurred due to deman...

Abstract Modern, intensified aquaculture typically involves three production phases; hatchery, nursery, and grow-out. For redclaw crayfish however, such delineation has been ill-defined. Farming of was initiated based on the putative beneficial physical biological attributes species, which suggested methods would be relatively simple. The simple approach proved to inefficient only partially eff...

Aquaculture currently accounts for approximately half of all seafood produced and is the fastest growing farmed food sector globally. Marine bivalve aquaculture, farming oysters, mussels clams, represents a highly sustainable component this industry has major potential global expansion via increased efficiency, numbers of, production systems. Artificial spat propagation (i.e. settled juveniles)...

Benedenia disease caused by the ectoparasite Benedenia seriolae is a serious parasitic disease in yellowtail aquaculture, leading to secondary viral or bacterial infections. Benedenia disease is difficult to prevent in marine aquaculture systems. To evaluate the genetic basis of Benedenia disease resistance in yellowtail, a genome-wide and chromosome-wide linkage analysis was initiated using F1...

Hatchery production of Chinook Salmon Oncorhynchus tshawytscha in the Columbia River basin comprises most anadromous salmonid this region. facilities and programs serve to mitigate for impacts salmonids due construction operation hydropower dams habitat from development addition conservation restoration natural populations. A genetic method referred as parentage-based tagging (PBT) enables high...

A field survey had been done for 41 fish farms in the districts of Maysan governorate during 2008.The Results showed that highest number was at centre city Amarah and Alkahala(24.4%). The (16) established 2007.The total area is 1262.5donam (donam= 1/4 hectare). largest water found Almejar (853 donam= 67.5%) lowest Almaemona (13 2.44%.). with less than 10 donam were 26 (63.4%). recorded district...

Chicken eggs incubated under hatchery conditions for 19 days show significant decreases in the total content of water and organic nitrogen, but not of sodium or potassium. The hypothesis is discussed that the formation of gaseous nitrogen is responsible for the nitrogen loss.
