Mass mortalities of the larval stage giant freshwater prawn, Macrobrachium rosenbergii, have been occurring in Bangladesh since 2011. Mortalities can reach 100% and resulted an 80% decline number hatcheries actively producing M. rosenbergii. To investigate a causative agent for mortalities, disease challenge was carried out using infected material from hatchery experiencing mortalities. Moribund larvae were prepared metatranscriptomic sequencing. De novo virus assembly revealed 29 kb...
In shrimp culture, various diseases, white spot syndrome virus (WSSV) in particular, has been emerging as a serious constraint affecting culture Bangladesh. this study, effort given assessing the risk factors for WSSV outbreak under which 72 farms were investigated belonging 4 Upazilas of Bagerhat (Kochua, Rampal, Fakirhat) and Khulna (Paikgacha) district Bangladesh from January to June 2011. Major scenario depicted improved traditional method. PCR test carried out confirm infection. About...
Mud crabs have a functioning innate immune system. Probiotics considerable effect in improving responses gravid mud crab. The current study investigated the influence of three lacto-sacc concentrations (T1=0 %, T2=1 and T3=1.5 %) 45 % protein 12 lipid meal on response crabs. Three groups wild (average weight: 122.33±1.53 g) were raised individually bamboo spawning boxes at mangrove pens for weeks. Wild (T4) also caught from river during breeding season tested to offer more exact assessment...
Although, Escherichia coli is widely distributed in the environment, only a small percentage pathogenic to humans. The most commonly encountered are those belonging Enterotoxigenic (ETEC), Enteroinvasive (EIEC), Enterohaemorrhagic (EHEC) and Enteropathogenic (EPEC) subtypes. Aquaculture premises specially shrimp farm tropical subtropical countries largely susceptive different types of E. strains. With PCR system, an attempt was taken identify virulent rapid basis from water, sediment live...
Green water indoor tank culture (GWT) of Tilapia with carp is an appropriate method for commercially producing in substitutional different bodies likes ponds, lakes, cages and reservoirs etc. that have environmental constraints such as land use conflicts, source water, quality sub optimal temperatures, where a green house could be used to control temperature minimizing the all possible constraints. This study showed high densities feeding rates can maintained through continual aeration solid...
Background and Objectives: Tilapia lake virus (TiLV) has been marked as an emerging infectious agent that causes mass die-offs in farmed mono-sex Nile tilapia (Tilapia niloticus) Bangladesh, indicates rapid diagnostic assay.This study was aimed to develop molecular detection method confirm the TiLV niloticus construct a genetic baseline control this disease. Materials Methods:The research aims of followed by complementary techniques PCR based approaches such reverse-transcription polymerase...
This study was aimed to develop a faster single step multiplex PCR protocol for the simultaneous detection of white spot syndrome virus (WSSV) with its host (i.e. shrimp) as internal positive control. To do so, four combinations primer were tested (I. 16S rRNA+Lo F1R1; II. F2R2; III. F1R2; IV. F2R1) which selected based on two pairs WSSV specific (Lo F1R1 and Lo F2R2) one pair shrimp (16S rRNA). DNA extracted from infected amplified by in tube using each thermal cycling conditions well...
White spot disease (WSD) occurred by the highly devastating white syndrome virus (WSSV) poses a serious impediment toward global shrimp production. We investigated molecular diagnosis and natural infection with WSSV in cultured tiger (Penaeus monodon) inspected histopathology of WSD. The incidence was recorded six small-scale farms situated two districts Bangladesh, namely Bagerhat Satkhira. One- two-step nested polymerase chain reaction models were applied to check presence DNA samples. By...

White Spot Disease (WSD), caused by Syndrome Virus (WSSV), a devastative killer in shrimp farms, causing severe economic loss to the farmers. This study investigated immune boosting activity of lipopolysaccharides (LPS) against WSSV infection, extracted from newly isolated bacterial strain under genus Pseudoalteromonas, Pseudoalteromonas sp. SRSBD1_22, hepatopancreas tiger shrimp. LPS was administered orally experimental (Penaeus monodon) for 5 days three groups at 3 (T1), (T2) and 7 (T3) μg...
A preliminary observation was conducted on the culture potentiality, domestication at different stocking density and breeding competency of Chaka chingri (Penaeus indicus) in southwest region Bangladesh from February to May 2020 Shrimp Research Station, Bagerhat for 120 days. There were three treatments with replication each where varied. Among treatments, T3 (200 nos./dec) found more suitable higher growth than T2 (300 T1 (400 nos./dec). In regular samples wild taken regions Bagerhat,...
Climate change poses significant threats to biodiversity in coastal ecosystems, resulting habitat degradation, species migration, population declines, and reduced ecosystem services. This study examines the impacts of rising sea levels, ocean acidification, temperature fluctuations on mangroves, coral reefs, seagrass meadows, which serve as critical habitats for marine species. Key findings reveal substantial loss, shifts, a decline vital services such carbon sequestration, fisheries...
1 Abstract Mass mortalities of the larval stage giant freshwater prawn, Macrobrachium rosenbergii , have been occurring in Bangladesh since 2011. Mortalities can reach 100% and resulted an 80% decline number hatcheries actively producing M. . To investigate a causative agent for mortalities, disease challenge was carried out using infected material from hatchery experiencing mortalities.

The study was conducted through 24 individual surveys in the SME of Bangladesh covering 16 river/canals and 32 locations (one-third area) Sundarbans by direct interviews randomly selected 1,989 fishermen from 545 non-mechanized boats 1,428 active gears eight types gear.The source credit, agreement Dadan, variability prices, profit distribution between boat/gear owner fishing labour, catch volume, relation fisher landing centers (i.e., intimacy expected market prices) were found to be...
To assess the growth and culture potentials of Indian white prawn Penaeus indicus, locally knownas Chaka Chingri, a preliminary trial was conducted for period 145 days in earthen ponds. The postlarvae were collected from Sundarbans coast stocked 3 ponds 0.056 ha each with stockingdensity at 30, 40 54 m-2in T1,T2 T3 treatments respectively. Commercial pelleted feed 36%protein fed. Production physico-chemical parameters recorded analyzed according tostandard methods. After rearing, obtained...
