The potential effectiveness of marine protected areas (MPAs) as a conservation tool for large sharks has been questioned due to the limited spatial extent of most MPAs in contrast to the complex life history and high mobility of many sharks. Here we evaluated the movement dynamics of a highly migratory apex predatory shark (tiger shark Galeocerdo cuvier) at the Galapagos Marine Reserve (GMR). U...

SL2/PU!culture is of central importance to the fisheries sector in Bangladesh. It grew from next to nothing in the early 1970s to contribute about 11% of total exports in the mid-1990s (DOF 1995). No other primary commodity enjoyed such spectacular growth in post-independence Bangladesh. Although shrimp farming has had a significant impact on the economy of Bangladesh, it has had high environme...

Abstract The effects of 17α-methyltestosterone administration on spermatophore quality in captive broodstock tiger shrimp Penaeus monodon were investigated using injection method and oral based the optimized protocol. experiment was designed to compare group with two replications during a 38-day experimental period. Captive male weighing 57-95 g collected from ponds stored 10,000 m 3 concrete t...

ABSTRACT: The effect of methods to remove protein content on the properties glucosamine hydrochloride from shells white leg shrimp (Litopenaeus vannamei) and black tiger (Penaeus monodon) was investigated. Chitin obtained by demineralization in 6% HCl for 12h, deproteinization two different (first group soaked 8% NaOH 36h second treated Alcalase enzyme at concentration 0.2% 36h). Two samples we...

Possible roles of algae (i.e. “green water”) in facilitating Macrobrachium rosenbergii larviculture have been investigated in the present study. Three types of algae were mixted with shrimp larval feed. Algal members were belonging to the family like Cyanophyceae, Chlorophyceae and Charophyceae respectively. Algal mixture was applied with control feed, showed better result in shrimp larval deve...

In a previous study, we demonstrated the existence of an emerging cluster of Vibrio nigripulchritudo that proved to be associated with shrimp mortality events in New Caledonia. Using sequence polymorphisms evidenced in this previous MultiLocus Sequence Typing study, we developed two new quantitative PCR assays permitting the detection and quantification of V. nigripulchritudo at the genospecies...
