In shrimps, lysozyme gene is expressed for protection against microbial infection. This current study targeted to determine the differences in expression in the samples from two different coastal regions having spatial variation for comparison. In the current study, diseased shrimps were collected from improved traditional ghers of Satkhira and Cox’s Bazar districts which are two different coastal areas of Bangladesh. Healthy shrimps were also collected from the ghers of those regions. Average relative expression of <em>lyso</em> gene in diseased shrimps from Satkhira region was lower than that of Cox’s Bazar region. Average fold-differences were observed 1.9, 2.3, and 2.5 in the shrimps collected from the ghers of Satkhira, and it was observed 2.6, 2.9 and 2.7 in the shrimp ghers of Cox’s Bazar. This study supports the hypothesis that immune-related gene expression might vary in different farms and regions in variations of water, environment and biological parameters for the state of the host.</p> <p>Asian J.

The present study was conducted to assess the effectiveness of using local and overseas Carp Pituitary Gland (CPG) in the induced breeding of <em>Cirrhinus mrigala </em>at Jashore district from April to May 2022. The first dose of hormone, both for male and female brood fishes were injected with local and overseas CPG at 0.5mg/kg body weight. After six hours of the first dose, only female brood fishes were injected with the second dose of PG at 5 mg/kg body weight. After 6 hours of second dose CPG injection of local and overseas PGs, brood fishes started spawning. The ovulation rates for both local and overseas PGs were estimated 100%. The fertilization rates were 93.5 % and 92.6 % for local and overseas PGs; while the hatching rates were 91.2% and 89.5%, respectively. However, local CPG is highly recommended to hatchery owners considering the rate of fertilization, hatching rate and availability.</p> <p>Asian J. Med. Biol.

The experiment consists of two factors. Factor A: F<sub>0</sub>: control, F<sub>1</sub>: vermicompost (10 t/ha), F<sub>2</sub>: N<sub>180kg.ha-1</sub>; P<sub>66kg.ha-1 </sub>K<sub>75kg.ha-1 </sub>and F<sub>3</sub>: ½ vermicompost (5t. ha<sup>-1</sup>) + N<sub>90kg.ha-1</sub>; P<sub>33kg.ha-1 </sub>K<sub>38kg.ha-1 </sub>Factor B: four levels of NAA, N0: 0 ppm, N1: 20 ppm, N2: 40 ppm and N3:80 ppm was used for the present study. The experiment was carried out in RCBD with three replications. Results showed that the highest yield of purple cabbage (27.38 t/ha) was found from the mixture of vermicompost and NPK treatment and the lowest yield (16.05 t/ha) was found from the control treatment. For different levels of NAA, the highest yield of purple cabbage (25.39 t/ha) was found from the N2 (40 ppm) treatment and the lowest yield (15.41 t/ha) was found from N0 (control) treatment. In the case of combined effect, the highest yield of purple cabbage (36.80 t/ha) was obtained from F3N2 (½ vermicompost and ½ NPK doses + 40 ppm NAA) treatment combination, and the lowest yield (6.64 t/ha) was found from F0N0 (control) treatment combination.</p> <p>Asian J.

Sixty fishermen were randomly selected for collecting data through a semi structured questionnaire. The current study discovered that there were 11 different fish species from six orders and seven families in the Habullah baor. All of the sampled fishermen were Hindu. About 25% of the fishermen was young aged, majority was middle aged and 25% was old aged group. A total of 75% of the fishermen had nuclear family and 25% families lived in joint family. Among the fishermen 85% had a few decimal of cultivable land and 15% were truly landless. Annual income of the respondents varied from 30,000 to 70,000 BDT with an average of 42,833 BDT. All fishers had access to drinking water from tube wells. Most of the fishers lived in katcha houses. About 15% of the fishers enjoyed electricity facilities in their home. Among the fishermen investigated, majority had earthen latrine, 20% used tin shed latrine, 8% used concrete latrine and a few of them 10% had no latrine. There were no modern medical facilities in the villages. The respondents had no alternate income sources during the dry season and at the time of ban period. The fishers as a whole are leading measurable life due to great financial hardship. Proper conservation and management measures can be taken to enhance the availability of fish fauna in Habullah baor, so that, the fishermen can harvest ample fish on sustainable basis.</p> <p>Asian J.
