Farmers of Bangladesh like to stock wild post-larvae (PL) Black tiger shrimp (Penaeus monodon). However, PL collection is detrimental aquatic biodiversity, and the supply hatchery sufficient. The study was conducted in Cox's Bazar, Bangladesh, compare quality aspects terms size variation, survival, tolerance, morphology.

Shrimp aquaculture plays the key role in Bangladesh seafood export industry. It includes species of Tiger prawn Penaeus monodon, and Giant river Macrobrachium rosenbergii, which have been widely farmed after 1980s. The industry is severely damaged due to diseases outbreaks hatcheries, nurseries grow-out ponds since 2000, thus this sector shows shrinkage from global market. However, last few dec...

The growth rate and mortality of giant prawns (Macrobrachium rosenbergii) in the Kuala Cenaku River, Indragiri Hulu Regency, Riau Province were carried out based on carapace length frequency data collected from May to July 2020. This study aims at River. For estimating dynamic population, analysed by using FiSAT II. parameter tiger shrimp was 0,78/year with asymptotic (L) 84,8 mm, total (Z), na...

Shrimp is one of commodity that has a great demand by consumers both domestically and abroad as an export commodity. There are 2 types shrimp cultivated in North Sumatra, namely Vannamei tiger prawns. Cultivation grown rapidly, replacing prawns' cultivation. The objective the study to analyse affecting production factors for cultivating shrimp. research location was determined purposively Medan...

The shrimp sector is the second largest export earner for Bangladesh, which is a major contributor in the national economy of Bangladesh. It also provides millions of employment. Every year a huge amount of shrimps are rejected to export due to its pathogenic bacterial contamination. A comparative study regarding prevalence and antimicrobial susceptibility of pathogenic bacteria in the black ti...

During the reproductive season, sea turtles use a restricted area in the vicinity of their nesting beaches, making them vulnerable to predation. At Raine Island (Australia), the highest density green turtle Chelonia mydas rookery in the world, tiger sharks Galeocerdo cuvier have been observed to feed on green turtles, and it has been suggested that they may specialise on such air-breathing prey...

The prostanoid pathway converts polyunsaturated fatty acids (PUFAs) into bioactive lipid mediators, including prostaglandins, thromboxanes and prostacyclins, all of which play vital roles in the immune and reproductive systems in most animal phyla. In crustaceans, PUFAs and prostaglandins have been detected and often associated with female reproductive maturation. However, the presence of prost...

BACKGROUND Persistent infection of Penaeus stylirostris densovirus (PstDNV) (also called IHHNV) and its non-infectious inserts in the black tiger shrimp, Penaeus monodon (P. monodon) genome are commonly found without apparent disease. Here, we introduced the method of multiplex PCR in order to differentiate shrimp with viral inserts from ones with the infectious virus. The method allowed us to ...

The main objective of this study was to obtain chitin in pure form from a new crustacean waste material for industrial applications. Black tiger shrimp shell wastes are a rich source of protein and valuable bioactive carbohydrate polymers such as chitin. After removal of carotenoid, Black tiger shrimp shell wastes (BTSHWs) were treated with chemicals and protease enzyme to extract chitin. Box-B...

Bacteriocin has been used widely in industry as a Backgrounds biopreservative agent. The objective of the present study was to investigate the potency of Bacteriocin isolated from tiger prawn and Penaeus monodon freshwater shrimp as an anti-bacterial on fish. Macrobrachium rosenbergii : A total of ten candidates of probiotic bacteria consisted of five Methods isolates from tiger shrimps (H1, H2...
