Effect of different feeding levels on water quality, growth performance, survival rate and body composition of Pacific white shrimp Litopenaeus vannamei post larvae were studied in zero water exchange system. Shrimp post larvae with mean weight of 74.46± 6.17 mg were fed for 32 days in 300L fiberglass tanks containing 130L water at density of 1 post larvae L-1. There were five treatments includ...

We tested the hypothesis that fate of dietary phosphorus will not differ among a dicalcium phosphate-free practical diet treated with 6-phytase (3000 FTU/kg; Quantum Blue™; P-F + Phy), and positive (C) negative (P-F) control diets when fed to hybrid tilapia (Oreochromis aureus x O. niloticus; 29.8 g initial weight) stocked at 29 fish/m3 grown for 5 months market size (454 g/fish) in outdoor bio...

The effects of two waste sources, red hybrid tilapia (Oreochromis sp.) and whiteleg shrimp (Litopenaeus vannamei), drying methods (freeze-drying oven-drying) on the proximate chemical composition bioflocs were investigated. In total, four kinds experimentally treated compared to identify best source method produce biofloc an acceptable nutrient value: freeze-dried (FDSBF), oven-dried (ODSBF), (...

Currently, aquaculture seeks to implement production models that keep up with the global demands for sustainability and reduced environmental impacts. One of options adopted is integrated multi-trophic (IMTA), which cultivates species different trophic levels, improving use nutrients increasing economic profitability system. On other hand, Biofloc Technology system (BFT) has also been highlight...
