A global interest in Silver Barb (Barbonymus gonionotus) cultivation has arisen because of a combination declining wild stock and steady increase demand market value. The purpose the current investigation was to evaluate impact extreme water temperature changes on growth, hemato-biochemical responses, pepsin enzyme activity gill histomorphology B. gonionotus. Four distinct temperatures (22, 26, 30 34 °C) were applied laboratory triplicate glass aquariums (150 L each). At 22 °C, respectively,...

An integrated experiment was performed on juvenile Malabar blood snapper (Lutjanus malabaricus) to investigate the effect of temperature and diet in their pepsin activities relation with digestive somatic index (IDS) relative gut length (RGL). One hundred twenty L. malabaricus (13–15 cm) were equally distributed among four exposed treatments (22, 26, 30 34 °C) representing seasonal range account for end century predicted temperatures, two diets as commercial pellet natural shrimp. After 7...

Global climate change is impacting and will continue to impact on marine estuarine fish fisheries. Data trends show effects ranging from growth, digestion physiology performance in freshwater ecosystems. The present study was designed develop a concept for cause effect understanding with respect climate-induced temperature salinity changes explain ecological findings based physiological processes. wide comparison of species. preliminary conclusion can be drawn that warming shift distribution...

The hilsa shad, Tenualosa ilisha (Clupeidae, Clupeiformes) is an important anadromous clupeid species from the Western division of Indo-Pacific region. It constitutes largest single fishable in Bangladesh. Information on genetic variability and population structure very for both management conservation purposes. Past reports T. involving morphometric, allozyme RAPD analyses are contradictory. We examined divergence two riverine (the Jamuna Meghna), estuarine (Kuakata Sundarbans) one marine...

This research was carried out to assess the effects of dietary chitosan on immunity and reproductive performance adult Barbonymus gonionotus. The fish (average weight 66.7 ± 0. 86 g) were randomly divided into four treatments: control (0.00 g/kg), CHT-1 (1.00 CHT-2 (2.00 g/kg) CHT-3 (3.00 fed appropriately formulated diets for 60 days. results showed significant differences in immunological parameters such as lymphocytes, neutrophils, monocytes, immunoglobulin (IgM), lysozyme activity...

A field experiment was conducted at the research of Agronomy Division, BARI, Joydebpur, Gazipur and ARS, Burirhat, Rangpur to evaluate crop growth, yield seed quality garden pea in prevailing temperature different sowing dates (10 November, 20 30 10 December, December December). Sowing date based variations significantly affected TDM production, BARI Motorshuti-3. Plants with November 20-30 performed best respect contributing characters. However, delayed dates, temperatures later growth...

The plasma membrane of the human pathogen Leishmania donovani possesses a high-affinity transmembrane Ca(2+)-ATPase that has its catalytic site oriented toward cytoplasmic milieu (Ghosh, J., Ray, M., Sarkar, S., and Bhaduri, A. (1990) J. Biol. Chem. 265, 11345-11351). When enzyme is studied in more authentic, physiologically relevant, membrane-associated form, it exhibits pronounced sigmoidal kinetics with Ca2+ (K0.5 approximately 700 nM) trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetic...

Glutathione (GSH) 0 (control), 2, 4 and 8 mM was used in the preservation of chilled goat semen. Treated control samples were kept at – 5°C up to seven days. Sperm motility acrosome abnormality assessed daily under phase contrast microscope. The sperm significantly (P<0.01) higher semen treated with GSH. Optimum (≥50%) for artificial insemination retained three days 2 GSH four Acrosomal damage reduced ≤ 1.0% after addition It is suggested that may be as an antioxidant better insemination....

Beel is one of the ancient types and obviously a fascinating due to its biodiversity ecological importance in local national perspective Bangladesh. The Bhawal beel important beels excellent habitat for small indigenous species (SIS). present status decline causes was studied from March 2016 February 2017. Data collection carried out four villages Achim union under Fulbaria upazila. Questionnaire Interview (QI), Focus Group Discussion (FGD) cross-check were done obtain data related fishes...

The inadequate supply of tilapia seed mostly fingerling which consider as the secured stock because lower mortality rate is considered one major present constraints to development culture industry in annual flooded region haor Bangladesh.The floating bamboo net-hapa nursery system was observed be very efficient mass production fingerlings at water body Sunamganj district, Bangladesh.This therefore, recommended for small-scale (artisanal) commercial operators consisting fishermen families...

Different reproductive aspects such as sexual maturity, spawning, gonadosomatic index, fecundity, and histological changes in gonads of captive reared Sperata aor were investigated for a period one year. Male female fish identified by based on morphological characteristics. The spawning season was found to be extended from May-August. Gonadosomatic index reaches maximum August lowest September. Absolute fecundity varied 59255 70586 with an average value 64920. had been reported increased...

The current study compared the length-weight relationships and condition factors in mono- mixed-sex Nile tilapia (Oreochromis niloticus). trial lasted for 91 days included two treatments with five replications each, all same stocking density. During period, 20 randomly selected fish individuals were measured recorded from each cage every weeks. observed growth trend was allometric, no significant difference mean exponential values (b), 2.696 2.65 mono respectively. There a final weight gain...

This study is conducted to examine the impacts of different rearing temperature and diet variation on haematological serum biochemical parameters juvenile Lutjanus malabaricus, a commercially important fish species in were divided into eight treatments (4 temperatures × 2 diets) each with three replicates five juveniles each.Fish subjected four (22, 26, 30 34°C) fed commercial pellet natural shrimp diet.After days experimental period, blood samples collected transferred two tubes from...
