Population dynamics of Lysmata Ensirostris in the Kutubdia channel of the Bay of Bengal, Bangladesh

FiSAT (FAO ICLARM Stock Assessment Tools) programme was used to estimate population parameters of Lysmata ensirostris from length frequency data. The La (asymptotic length) and K (growth coefficient) were found to be 7.3 cm and 2.2/year respectively and the growth performance index (?) was found to be 2.069. An additional estimate of La Z/K was found to be 7.057 cm and 1.086 respectively. The annual rate of natural mortality (M), fishing mortality (F) and total mortality (Z) were found to be 8.44, 0.92 and 9.36 respectively. The selection pattern was found to be 5.642 cm.

Catching and rearing postlarval cleaner shrimp for the aquarium trade: results from a WorldFish Center project in Solomon Islands

Between 1999 and 2003, the WorldFish Center in Solomon Islands conducted research into the feasibility of a new fishery based on the capture and culture of postlarval coral reef fish for the live fish trade. The work was carried out in two phases: a research phase from late 1999 to the end of 2002; and a “finetuning” phase in 2003. Most of the species were of value to the marine aquarium trade, with very few live reef food fish recorded. The most valuable ornamentals were the banded cleaner shrimp, Stenopus species.

Applying Resource Management Domain (RMD) concept to land and water use and management in the coastal zone: case study of Bac Lieu province, Vietnam

Because of changing hydrological conditions due to infrastructure development to prevent salinity intrusion into the coastal zone, local authorities in Bac Lieu Province, Vietnam, faced complex natural resource management issues concerning managing saline and freshwater resources to support diverse production activities in the coastal zone while farmers had to adjust their production strategies.

Some aspect of population dynamics of three penaeid shrimp (P.monodon, P.semisulcatus and M.monoceros) from the Bay of Bengal, Bangladesh.

In the Bay of Bengal of Bangladesh area the values of asymptotic length (La) for tiger shrimp (Penaeus monodon), green tiger shrimp (Penaeus semisulcatus) and brown shrimp (Metapenaeus monoceros) were found to be 30.0 cm, 23.5 cm and 16.5 cm for male and 32.1 cm, 27.0 cm, and 19.4 cm for female respectively while the growth co-efIicient(K) were 0.94, 0.80 and 1.5 year¯1 for male and 0.97,0.90 and 1.52 year¯1 tor female respectively.

The good, the bad and the ugly: discourse, policy controversies and the role of science in the politics of shrimp farming development.

This article revisits through a policy analysis the ongoing debate on shrimp farming aquaculture. It describes the changes in policy orientations that have takenplace in recent years, and tries to relate them to the advocacy strategies developed by different networks and policy communities. The analysis reveals in particular the crucial contribution of the 'power of expertise' and shows how it has been instrumentalised by certain advocacy networks to depoliticise the debate.

Feasibility of shrimp culture in Brunei Darussalam.

The US-ASEAN Coastal Resources Management Project Team assessed the feasibility of brackish pond aquaculture development in Brunei. More than 2000 ha are identified as high priority sites for fishfarm development. Designs of brackishwater aquaculture farms with P. monodon as the target species, are prepared, together with estimates of development costs. The pond culture systems studied considered appropriate for Brunei are earthen ponds for semi-intensive culture, concrete-lined earthen ponds and fully concreted pond walls, both for intensive culture system.

An assessment of health management practices and occupational health hazards in tiger shrimp (Penaeus monodon) and freshwater prawn (Macrobrachium rosenbergii) aquaculture in Bangladesh

Diseases have been recognized as the major obstacle to the shrimp (Penaeus monodon) and prawn (Macrobrachium rosenbergii) aquaculture production in Bangladesh. The present study assessed the range of aquatic animal health problems encountered and management practices adopted by shrimp and freshwater prawn farmers through a systematic survey.
