The New Caledonia blue shrimp Litopenaeus stylirostris is commercially produced under semiintensive rearing conditions. The size of the farming earthen ponds (5–10 ha) and the subsequent production constraints make it difficult to use them as experimental units for random experiments. Moreover, since every pond has its own characteristics, ponds' effects cannot be ruled out, thus making it hard...

A multiple of stakeholder goals, regarding natural resource utilisation, are integrated into an overall provincial strategic forest and fisheries utilisation decision support system providing a platform for defining tactical forest planning objectives within a 10-year planning horizon. The case study area is a 5362 ha mangrove forest enterprise, divided into a buffer zone and a full protection ...

This paper reports on the statistical analysis of the 1995 survey of 451 shrimp farms in Thailand. The aim was to identify relationships which may indicate key issues for research into sustainability. Rigorous cleaning up of the data was carried out to eliminate cases where the data could not be validated or where a respondent consistently omitted data. In the subsequent analysis, nine key outc...

The Penaeus vannamei nodavirus (PvNV), which causes muscle necrosis in Penaeus vannamei from Belize, was identified in 2005. Infected shrimp show clinical signs of white, opaque lesions in the tail muscle. Under transmission electron microscopy, the infected cells exhibit increases in various organelles, including mitochondria, Golgi stacks, and rough endoplasmic reticulum. Cytoplasmic inclusio...

With the target of increasing the shrimp (Penaeus monodon) production through farm development and improved grow out management, an experiment was conducted with three different stocking densities viz. 5/m (T1), 7/m (T2) and 9/m (T3). Results of the experiment revealed that, among the water quality parameters, values of dissolved oxygen and transparency were lower in the higher stocking densiti...

Seafood consumption is in constant increase since 1960s. Though, there is diversity in seafood consumption worldwide (per capita/per year). The increase tendency of seafood consumption in the Europe can be predicted by the fact that average seafood intake among European population is around 7 kg/per year, while recommended amount is 14.5 kg.

A culture system for the commercial production of the seaweed Gracilaria parÕispora using shrimp-farm effluents for fertilization and floating cage-culture for grow-out has been developed on Molokai, HI. This two-phase system produces high-quality products for direct human consumpŽ . tion. The mean relative growth rates RGRs of effluent-enriched thalli in the cage system ranged y1 Ž y1. from 8....

The occurrence of various Vibrio species in water, sediment and shrimp samples from multiple shrimp farm environments from the east and west coast of India was studied. The relative abundance was higher in west coast farms (ca. 10(4) cfu/ml water) when compared to the east coast (ca. 10(2) cfu/ml water). Vibrio alginolyticus (3-19%), V. parahaemolyticus (2-13%), V. harveyi (1-7%) and V. vulnifi...

Drewes (updated, 2002) http://www.zool.iastate.edu/~c_drewes/ http://www.zool.iastate.edu/~c_drewes/Artemph.jpg Taxonomy Phylum: Arthropoda Subphylum): Crustacea Class: Branchiopoda (includes fairy shrimp, brine shrimp, daphnia, clam shrimp, tadpole shrimp) Order: Anostraca (brine shrimp and fairy shrimp) Genus and species: Artemia franciscana (= the North American versio...

A study was performed to investigate the genomic variations in the shrimp farm isolates of Vibrio alginolyticus and V. harveyi when the isolates were subjected to environmental stress. Samples of shrimps, water and sediment were collected from Southern Indian coastal shrimp farms. Vibrio isolates were biochemically identified and confirmed using 16S rDNA and gyrB gene specific PCR. The bacteria...
