This study aimed to evaluate the effects of water temperature during fertilization and egg incubation in the determination of the sex ratio of fingerlings of silver catfish Rhamdia quelen. Water temperatures of 19, 25 and 30°C were used during the egg fertilizations, and the eggs were then incubated at temperatures of 19, 25 or 30°C for each fertilization temperature condition. An increase in t...

A study was carried out to evaluate the probiotic activity of Bacillus subtilis G1 isolated from fermented pickles in growth performance and disease resistance of Hemibagrus nemurus fingerlings at Universiti Putra Malaysia. The probiotic was mixed in feed at doses of 0 (C, control), 3 x 109 (T1) 3 x 107 (T2) and 3 x 105 (T3) cfu g-1 and fed to the catfish fingerlings for nine weeks. Results sho...

Artificial fertilizers and mainly organophosphate herbicide are used by farmers to enhance their crop and control pests. In order to investigate the effects of Pretilachlore, fingerlings of caspian roach were exposed to a range of concentrations of toxin close to those of estuary for 96 h. Due to movement of these fingerlings in a gradient of salinity from freshwater to brackishwater some physi...

Plant based protein sources are one of the best, cost effective and easily available being used in fish feed. But due to a lower number micro-biota gut plant meal diets cannot be digested absorbed well body. Probiotics were supplemented at 0, 1, 2, 3, 4 5 gkg-1 levels feed for formulating control five test diets. In this study, three replicates each treatment fingerlings was 15 replicate. The C...

ABSTRACT Among a variety of hybrids produced in Brazil, tambatinga is obtained from the crossing tambaqui female with pirapitinga male. Although rapid weight gain less time an attractive characteristic commercial viewpoint, information on its nutritional requirements, especially amino acid limited. As corn and soybean meal-based diets available for fish contain deficient levels essential methio...

Mahseer aquaculture activities are still relatively low because they constrained by slow growth. Potassium diformate can promote growth improving digestion. This research aimed to determine the optimum dose of potassium addition artificial feed for best rate in mahseer fingerlings. The was conducted from July – August 2022, hatchery Faculty Fisheries and Marine Sciences, Padjadjaran University,...
