If you want to meet a truly tough fish, buy a ticket to Lake Magadi, Kenya. Here, the Magadi tilapia swim happily in the hot, alkaline waters of the lake, where oxygen levels soar and plummet daily and water chemistry pushes the boundaries of acid– base regulation. Few fish can survive such an extreme aquatic environment and this has attracted comparative physiologists for decades to the town o...

background: the current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of tilapia packed in polyethylene bags, which were kept in cool temperature of 4±1 °c. methods: prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (2% v/v) and ...

Tilapia (Oreochromis niloticus) is one of the freshwater fish commodities with important economic value. However, in tilapia aquaculture, emergence disease was problems that affect quality and quantity aquaculture production. One diseases often appears infection Aeromonas hydrophila bacteria. This problem expected to be overcome by giving vitamin C feed. Through provision C, it will able increa...

The acute toxicity of Roundup, a glyphosate herbicide, to Nile tilapia, Oreochromis niloticus, was investigated with emphasis on histopathological effects. The values of 24-h, 48-h, 72-h and 96-h LC50 for young tilapia were 17.5, 17.1, 16.9 and 16.8 ppm, respectively, and those for adult tilapia were 46.9, 44.4, 40.0 and 36.8 ppm, respectively. They indicated that adult fish were more tolerant ...

Lactococcus garvieae infection in cultured Nile tilapia, Oreochromis niloticus (L.), and pintado, Pseudoplathystoma corruscans (Spix & Agassiz), from Brazil is reported. The commercial bacterial identification system, Biolog Microlog, confirmed the identity of L. garvieae. Infectivity trials conducted in Nile tilapia using Brazilian Nile tilapia L. garvieae isolates resulted in a median lethal ...

The “greenwater culture” of the tiger shrimp, Penaeus monodon, is an innovative culture technique for the grow-out rearing of shrimps. This culture method involves the use of rearing water of tilapia for the rearing of tiger shrimp in grow-out ponds and or the polyculture of shrimp with tilapia. This culture technique was reported to prevent disease outbreaks attributed to luminescent Vibrio. T...

Tilapia are a commonly aquacultured fish yet little is known about their normal physiology and response to disease. In this study we determined the results of complete hematologic (n=40) and plasma biochemical profiles (n=63) in production tilapia (Oreochromis hybrids). The fish were raised in recirculating systems with a high stocking density (120 g/L), and were in the middle of a 15-month pro...

This research aimed to develop an electrolysis method to generate high-concentration chlorine dioxide (ClO2) for tilapia fillet disinfection. The designed generator produced up to 3500 ppm of ClO2 at up to 99% purity. Tilapia fillets were soaked in a 400 ppm ClO2 solution for 5, 10, and 25 min. Results show that total plate counts of tilapia, respectively, decreased by 5.72 to 3.23, 2.10, and 1...

The highly valued sea cucumber Holothuria scabra is currently listed as endangered (EN) species in the IUCN Red List due to overfishing in most of its native locations, spurring the development of H. scabra aquaculture to ensure sustainability of the industry and species in the wild. This review presents a summary on the biology of Holothuria scabra and recent advancements of its aquaculture te...
