the best method of fish breeding is the isolation of pure lines having high-producing hybrids. the decline in heterosis (dih) resulted from inbreeding, maternal effects, general combining ability (gca) and specific combining ability (sca) on reproductive traits (e.g., egg production, number of hatched egg, and hatchability of pure lines and crosses) of tiger, green, and albino barbie hybrids we...

Tarakan City is a hatchery center for giant tiger prawn larvae production. However, the quality of produced still far from expectations, namely free pathogens and capable being resistant to disease. Observation bacterial infection in growth phase was carried out determine cause proper treatment hatchery. The results showed that isolation bacteria prawns post using 3% TSA media obtained 8 isolat...

The study to evaluate the toxicity of used drilling muds (drilling wastes) and their impact on gill structure of the post larvae of tiger prawn Penaeus monodon has been done. The results showed that the 96 h LC50 of used drilling muds ranged from 30740 and 78271 ppm SPP. All toxicity values considered to be above the standard of Indonesian government (LC50≤30000 ppm SPP). Histological observati...

Climate reductive translations of migration attract international attention, but result in three problematic misreadings Bangladesh’s socioecological landscape. First, attributing to climate change misreads coastal vulnerabilities and the importance as a gendered livelihood strategy deal with rural precarity debt- both past present.

Crustacean allergy is a major cause of food-induced anaphylaxis. We showed previously that heating increases IgE reactivity of crustacean allergens. Here we investigate the effects of thermal processing of crustacean extracts on cellular immune reactivity. Raw and cooked black tiger prawn, banana prawn, mud crab and blue swimmer crab extracts were prepared and IgE reactivity assessed by ELISA. ...

Kerala state's rice consumption is predicted to be between 3.5 and 4 million tons per year, but production just a sixth of this. In order boost the production, attention must paid traditional growing techniques. Thus, there need understand Pokkali cultivation method used in Kerala. The style farming Kerala's acidic, saline soil distinctive way cultivation. A native historic salt-tolerant type c...
