Study was done to show the effect of triploidy on growth performance, survival rate and gender ratio on Penaeus merguiensis compared to diploid sibling otherwise identifying the sex external characteristic of the postlarval. Cold shocks (10°C, 15°C and 20°C) with control (28°C) and three different time of exposures (10, 15 and 20 min)were introduced to each treatments. The fertilization rate wa...

A major decline in the catch of the banana prawn [shrimp], Penaeus (Fenneropenaeus) merguiensis, occurred over a six-year period in the Weipa region of the northeastern Gulf of Carpentaria, Australia. Three main hypotheses have been developed to explain this decline: (1) prawn recruitment collapsed due to overfishing; (2) recruitment collapsed due to a change in the prawn's environment; and (3)...

Pemanfatatan sumber daya udang jerbung (Penaeus merguiensis) di perairan Kepulauan Aru dan sekitarnya sudah berlangsung cukup lama dilakukan sangat intensif. Untuk menjaga keberlanjutannya, dibutuhkan opsi pengelolaan agar ini dapat dimanfaatkan secara berkesinambungan. Tujuan penelitian adalah untuk mengkaji status stok kemungkinan sekitarnya. Penelitian pada periode survei 2013-2017 dengan me...

The present study aims to recognize dhow prawn trawl by-catch from Hormuzgan coastal waters (Northeast Persian Gulf). Sampling was carried out of 36 hauls by using traditionally wooden dhow among prawn fishing season in 2011. The catch composition consisted of 31.66% target species prawns, mainly banana prawn (Penaeus merguiensis) and 68.34% by-catch. The total by-catch was 4,622.67kg com...

Mangroves are traditionally considered to provide important nutrition to tropical estuarine consumers. However, there is still controversy about this, and the extent and importance of these inputs are largely unquantified. In particular, there is no information for food webs of small estuaries that dominate wet–dry tropical coasts, where freshwater inflow is intermittent, leading to highly seas...

It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens. By comparison, losses to fungi and parasites have been relatively small. For bacterial pathogens, Vibrio species are the most important while for viral pathogens importance has changed since 2003 when domesticated and genetically selected stocks of t...

Timely pond-side detection of white spot syndrome virus (WSSV) plays a critical role in the implementation of bio-security measures to help minimize economic losses caused by white spot syndrome disease, an important threat to shrimp aquaculture industry worldwide. A portable device, namely POCKIT™, became available recently to complete fluorescent probe-based insulated isothermal PCR (iiPCR), ...
