the effects of weight and length of barbus grypus broodstock on fingerlings reproductive characteristics and growth were investigated. we chose three female treatments  including weight and length groups (1) 2212.5±479g,  62.68±6.7cm, (2) 4518±780g,  79.12±4.36cm  and (3) 7712.5±1171g, 92.62±3.13cm. the same male broodstock were used for all the treatments with the weight and length size of 140...

 Contribution change of factor costs analysis may help managers in decision making and in adjusting to changes. Over the last two decades, production and enhancement of kutum fingerlings have increased in Iran, reaching to more than 229 million fingerlings by 2005, but declined to 187 million from 2005 to 2008. Over the years 2002-2006, a study of fingerling production costs for kutum fish was ...

Fish farming faces the challenge of high cost feeds because high-quality protein like fish meal required in food formulations. Therefore, need for alternative sources is much needed. Black soldier larvae (Hermetia illucens) are feed containing protein. BSF contain levels (42.7% dry matter; DM). diets should 32% to 45% content. it can be a substitute meal. This study was conducted investigate ef...

To determine if molybdenum (Mo) is a chemical stressor, fingerling and juvenile rainbow trout (Oncorhynchus mykiss) were exposed to waterborne sodium molybdate (0, 2, 20, or 1,000 mg l-1 of Mo) and components of the physiological (plasma cortisol, blood glucose, and hematocrit) and cellular (heat shock protein [hsp] 72, hsp73, and hsp90 in the liver, gills, heart, and erythrocytes and metalloth...

WillomitzerJ J.: Seasonal Dynamics of Parasitoses in Grasscarp (Utenopharyngodon idella) Fry and Fingerlings. Acta vet. Brno, 49, 1980: 269 277. Examination of grasscarp (Ctenopharyngodon idella) fry and fingerlings from the State Fishery, Pohorelice, for 3 years revealed grasscarp infestation with 12 parasite genera or species. The intensity and extensity of infestation was highest in the peri...

The use of probiotic bacteria can not only enhance the nutritional utilization fish feeds to produce more biomass but also provide a practically “safer” alternative farming industry reduce abuse antibiotics and drugs. This study investigated possibility colonizing Lactobacillus rhamnosus strain GG (LGG) intestine Cirrhinus molitorella (mud carp) fingerling. Colonization LGG was observed in gut ...
