Fish is traditionally complemented to rice in the diet of Bangladeshi. Thus, its daily consumption is pretty normal. Although, a number of researches have been done on river fish and its consumption, there seems a few in the public that specifically studied consumer preference for sea fish consumption in Bangladesh. This study, therefore, explores...

Though shrimp is the second largest exportable product in our country,the rising graph of shrimp production has been severely punctuated by disease. Recently researchers found that using of fermented carbohydrate in aquaculture is the most effective means to prevent diseases. It also strives to simulate natural estuarine conditions by creating zoop...

Epiphytic algae in mangrove forests contribute to high productivity in these unique mangrove ecosystems. A general survey of mangrove-associated macroalgae was conducted during February-March (dry season) and November-December (wet season) in the Sundarbans Mangrove Forest, Bangladesh. Different macroalgae were collected from mangrove pneumatophore...

Inter‐specific hybrids are usually formed by mating two different species in the same genus. They have been produced to increase growth rate, improve production performance, transfer desirable traits, reduce unwanted reproduction, combine other valuable traits such as good flesh quality, disease resistance and increase environmental tolerances, bet...

Seaweeds are used as a source of food around the areas of Asian countries, such as Japan, China, and South Korea. Naturally, seaweeds possess different kinds of polysaccharides. They are used as raw materials in the cosmetic, food, and pharmaceutical industries. In the current chapter, we discussed about the ultrasonic assisted extraction method fo...

Vibrio alginolyticus is an important opportunistic pathogen in humans and marine animals. Culture-based methods and the traditional polymerase chain reaction (PCR) cannot quantify the pathogen with sufficient sensitivity. Thus, reliable, rapid, and accurate detection and quantification methods are essential to prevent and control V. alginolyticus....
