... evaluate the effects of biofloc technology (BFT) on growth, nutrition and economic profitability in mudflat fish aquaculture. A 60-d experiment was conducted in zero-water exchange BFT system. The results demonstrated that weight gain (WG), specific growth (SG) and survival in BFT group were 133.94%, 1.20% day^-1 and 90.0%, respectively. In control group with a 1/4-1/3 daily water exchange, WG, SG and survival were significantly lower than those in ...

Effect of Water of Tilapia Pond on Reproduction of Meloidogyne incognita and Growth of Eggplant in Relation to Soil Type

...(STP), intensive tilapia biofloc (ITB) systems, and well water (WW), on the reproduction of Meloidogyne incognita infecting eggplants7 or 45 days after planting in sandy loam or sandy soils. Each irrigation source was applied daily at 150 mL/pot. The STP source was more suppressive to nematode development than ITB irrigation source in the two inoculation times of treatments either in sandy soil or sandy loam soil. Also, the produced eggs were highly influenced...

The diets were fed to red Tilapia fingerlings (14.3 ± 0.15 g) thrice a day. The study lasted fourteen weeks. Feed utilization, growth performance, morphological fish characters, chemical fish composition, flesh color, and blood profiles were determined. The obtained results illustr...

...ultivation sites using a biofloc system were selected using saturated sampling based on the sustainability of the catfish business (5 years), which included 20 businesses. Ectoparasite observations were conducted using a ZEISS Axioscope 5 Smart Laboratory Microscope. The descriptive method was used to identify and analyze the observational results. Gyrodactylus and Dactylogyrus parasites were discovered in mucus and gills. The Vorticella parasite was found on ...

... in aquaculture, such as biofloc technology, robotic systems, sensor-based monitoring, and nano-vaccinology, have significantly improved fish farming productivity and strengthened the economic stability of fish farmers. However, freshly harvested fish undergo rapid biochemical changes, including rigor mortis, oxidative spoilage, autolysis, and microbial degradation. These processes lead to the breakdown of various compounds, causing undesirable changes in odor...
