The small indigenous species, namely Ailiichthys punctata (Day, 1871), Botia lohachata (Chaudhuri, 1912), Chanda nama (Hamilton, 1822), Laubuca laubuca 1822) and Mystus cavasius comprise an important component of riverine fisheries Bangladesh. This study describes the length–weight relationships (LWRs) length–length (LLRs) five threatened fishes from Jamuna River, a distributary Brahmaputra River in northern A total 919 specimens species families used for this were caught by traditional...
In the present study, surface water samples were collected during three seasons (summer, monsoon and winter) from four different study sites (T-dam, Padma Garden, I-dam Talaimari point) of River at Rajshahi, Bangladesh, various physicochemical bacterial parameters analyzed based on standard methods. Significant differences (p < 0.05) in observed among except for temperature. However, fecal coliform, other such as total heterotrophic bacteria, coliform Vibrio cholerae counts showed...
This study describes the size at first sexual maturity, length–weight relationships (LWR) in relation to and Fulton’s condition factor (KF) of Eutropiichthys vacha Ganges River, northwestern Bangladesh. Sampling was done using traditional fishing gear including cast nets, square lift nets conical traps during January April, July December 2010. For each individual, total length (TL) measured nearest 0.01 cm, weight (BW) determined g. The gonadosomatic index (GSI) calculated by equation, GSI...
Macro-benthos is commonly considered an indicator for evaluating the health of aquatic ecosystem. Earlier research from sub-tropical mangrove estuaries, however, has primarily relied on conventional taxonomic methods to determine pattern macro-benthos diversity. Therefore, this study aimed describe both and functional groups with respect ecological variables in three separate seasons (pre-monsoon, monsoon, post-monsoon) a mangrove-dominated Pasur River estuary, Bangladesh. The findings...
Metal pollution in the surface sediment of Pasur River estuary was investigated to assess its distribution, potential sources, and current dangers ecological public health. The is a tidal, meandering, perennial river south-western Bangladesh with considerable number fisheries industrial activities. Sediment samples were collected from seven sampling points January December 2022 contamination level six potentially toxic elements (Pb, Cr, Cd, As, Cu Zn). Flame Atomic Absorption...
The present study describes the size at first sexual maturity, fecundity, length–weight (LWRs) and length–length relationships (LLRs) of pool barb, Puntius sophore, using data obtained from different geographical locations in Bangladesh. A total 905 specimens were caught by traditional fishing gear March 2010 to February 2011. Additionally, a 121 females collected commercial catch Padma River during June–July 2011 estimate maturity determine fecundity. Total length (TL), fork (FL) standard...
Heavy metals contamination of water is considered as severe global issues for developing countries like Bangladesh. Because heavy metal pollution ruined aquatic ecosystem especially fish diversity which contribute important share on economy a country. The present study designed to investigate the level lead (Pb), chromium (Cr), cadmium (Cd), copper (Cu) and zinc (Zn) in surface Bakkhali river estuary decreasing order concentration was Cu>Zn >Cr>Pb>Cd with mean value 2.6> 0.825...
The present study describes the length-weight relationships (LWRs), length-length (LLRs), Fulton's condition factor (KF), size at first sexual maturity, spawning season, sex ratio and fecundity of Morari Aspidoparia morar (Hamilton, 1822) (Cyprinidae). Sampling was done using traditional fishing gear jhaki jal (cast net) from July 2010 to June 2011. Total length (TL), fork (FL) standard (SL) were measured with digital slide calipers. Individual body weight (BW) gonad (GW) determined an...
A study was carried out in nine fertilized fish ponds under three treatments (T-I, T-II and T-III) at Bangladesh Agricultural University, Mymensingh to see the bloom of euglenophytes with intention observing its impact on growth culture condition. Some water quality parameters viz., temperature, dissolved oxygen, pH, PO4-P NO3-N concentration some biological phytoplankton population were monitored fixed intervals. Euglenophytes showed a heavy late August T-II. The occurred by genera,...
The occurrence and abundance of cyanobacterial population was monitored monthly in two urban fish ponds Rajshahi City Corporation area from January to December, 2006. bloom observed March, August September. Some environmental parameters such as water temperature, transparency, pH, Dissolved Oxygen(DO), free Carbon dioxide(CO2), Biological Oxygen Demand (BOD), NO2-N, NH3-N, NH4+, toxic ammonia, Oxidation reduction Index (rH2) were recorded their relationship with the formation by...
Suitable stocking density of Gulsa tengra (Mystus cavasius) was observed by measuring growth performance, production, and survival in nylon net cages for 120 days Chalan Beel floodplain ecosystem. Fry Gulsha (5.55 ± 0.49 g weight) were stocked into 6 × 3 2-m (36 m3) floating with treatments: T1-50, T2-100, T3-150, T4-200 fry/m3 (in triplicates). The fry fed twice daily commercial pellet containing 32 % protein at the rate 5 /fish body weight during first 2 months then reduced to next months....
