Abstract Tropical hilsa shad, which is an anadromous fish migrating from the sea to spawn in freshwater river, constitutes important fishery some Asian and Middle East countries, particularly Bangladesh. But, historical information on biology ecology has confronted scientists policymakers with research management challenges. We have reviewed both old recent findings document status of knowledge potential gaps, necessary comprehend for formulating a more effective plan. Thus, there been...
The bacterial population plays a crucial role in recycling the organic matter and metabolizing toxic nitrogenous compounds under biofloc technology (BFT). has been successfully implemented for several fish species, but not shrimp culture Bangladesh. major objectives of this study were to determine effects stocking density on growth performance tiger Penaeus monodon (BFT) rearing system using commercial probiotics investigate abundance total heterotrophic bacteria (THB) vibrio-like (VLB)...
Abstract Development of a blue economy is firmly embedded in the development plans Bangladesh. Advances freshwater aquaculture have promoted Bangladesh to fifth largest fish producer world. However, marine resource base Bangladesh, which now even greater following recent settling disputes regarding maritime boundaries with neighbouring countries, lends itself aquaculture—known as mariculture. Several potential areas and opportunities for mariculture been identified implementation under...
Seaweeds can play an essential role in controlling antibiotic resistance for bacterial diseases. Three extracts of two brown seaweeds Padina tetrastromatica and Sargassum ilicifolium were investigated as growth promoters to provide immune protection against Vibrio parahaemolyticus. Extracts the administered at 2.5 5 g kg−1 with food 45 days Penaeus monodon juveniles. The maximum weight gain (6.28 7.08 g), specific rate (3.39 3.32%), survival (78.45 82.45%) juvenile tiger shrimp obtained a...
Among the various potential sources of renewable energy, biofuels are most interest. Marine microalgae promising oil for making biofuels, which can grow very rapidly and convert solar energy to chemical via CO 2 fixation. The fatty acid profile almost all microalgal is suitable synthesis biofuel. In this research, lipid contents Bangladeshi strains marine Skeletonema costatum were performed. For this, crude was extracted by Soxhlet extraction method, using three common solvent systems, pure...
To understand the present status of fish diseases and their remedial measures taken by farmers, a questionnaire survey Participatory Rural Appraisal (PRA) tools including Focus Group Discussion (FGD) were conducted in seven districts Bangladesh. In total 196 farmers interviewed nine FGD sessions conducted. Disease occurs immediately after stocking (24%) during rainy season (21%) followed cold (19%). Mortality, abnormal swimming feeding behavior, unusual appearance, some localized lesions...
AbstractSize frequency and length–weight relationships (LWRs) for three cephalopods, Indian squid Photololigo duvaucelii, needle cuttlefish Sepia aculeata, spineless Sepiella inermis were studied. Specimens caught from the coastal waters of Bangladesh (Moheshkhali Channel Sonadia Island) using both trawl marine set bag nets. The maximum dorsal mantle length squid, cuttlefish, was recorded to be 228, 135, 82 mm, respectively. estimated growth coefficient b 1.377 2.504 1.979 cuttlefish. these...
The recent incidence of loose-shell syndrome disease (LSSD) in grow-out shrimp ponds appears to be a major problem Bangladesh. Therefore, the aims our study were (i) observe clinical signs LSSD confirm its and (ii) identify probable causative agents for shrimp. Sampling was conducted randomly from five LSSD-affected three non-affected near Bakkhali River; ecological parameters measured. A total 180 healthy shrimps used this experiment, where extracts either injected into or mixed with water...
Asian seabass, Lates calcarifer is a highly valuable and potential candidate species for mariculture. The objectives of the present study were to conduct an onboard fertilization trail produce viable offspring see effects stocking density eggs on fertilization, hatching survival rate seabass juveniles. Eggs sperm collected during full moon in May 2019 from Moheshkhali channel estuary, Northeast Bay Bengal, by hand stripping method. Pooled two males female used insemination. Three egg...
The present investigation was undertaken in order to evaluate the cytotoxic effect of two D-galactose-binding lectins using brine shrimp lethality bioassay technique. Both were purified from marine invertebrates, sea hare Aplysia kurodai eggs and polychaete Perineries nuntia by conventional affinity chromatography methods. molecular mass egg lectin (AKL) determined be 32 kDa 56 sodium dodecyl sulfate polyacrylamide gel electrophoresis under reducing non-reducing conditions, respectively. On...
Chlorococcum sp. has been studied as its possibility for biofuel feedstock. This alga was grown in Zarrouk media. After harvesting, lipid extraction done by pure n-hexane and mixture of chloroform: methanol (2 : 1)) hexane: ethanol (3 1). Highest oil recovery (21.20%) derived from 1) solvent system dry biomass whereas the lowest (2.83%) came n-hexane: wet biomass. GC/MS used analysis extracted revealed that, palmitic acid methyl ester (C17H34O2), 9-octadecenoic (C19H36O2) were major contents...
The activity concentration of natural and anthropogenic radionuclides in soil rock, benthic algae, corals oysters across the St. Martin's island Bangladesh were investigated together with physicochemical parameters texture an aim evaluating radioecology island. Soil rock samples from twenty-two locations island, eleven species six two analyzed. 226Ra was found range 7.22–103.8, algae 2.5–9.7, coral 5.5–10 oyster 4.2–11.5 Bq kg-1. 232Th 14.56–216, 1.3–12.6, 4.4–15.6 3.2–8.4 kg-1; 40K 322–732,...
The physico-chemical parameters of water were assessed between Kalatoly coast and a shrimp hatchery to understand the present status quality. This study was conducted from January 2008 June at Cox's Bazar, Bangladesh. Water samples collected twice monthly coast. Similarly, ultra violet treated larval rearing tank also situated Kalatoly. temperature, salinity, dissolved oxygen pH more or less similar both in sea UV but highly variable (LRT). NO3 N NO2 N, PO4, Fe total solids moderately among...
A study was conducted between January - August, 2006 concerning the Penaeus monodon fry marketing systems in Bangladesh based on the existing one and economic evaluation of activities. In Bangladesh, P. wild hatchery reared ones is almost exclusively handled by private entrepreneurs. The Government has no command this issue except banning fry catching. market chain from catchers or producers to shrimp farmers passes through a number intermediaries: faria, traders, commission agents...
