This paper provides brief diagnostic characters of five previously reported grunt species: Plectorhinchus pictus (Thunberg, 1792); Pomadasys andamanensis McKay et Satapoomin, 1994; Pomadasys argenteus (Forsskål, 1775); Pomadasys argyreus (Valenciennes, 1833); Pomadasys maculatus (Bloch, 1793) and two new distributional records: Pomadasys guoraca (Cuvier, 1829) and Plectorhinchus macrospilus Satapoomin et Randall, 2000. The fishes were collected from the Saint Martin’s Island coral reef-like ecosystem and the adjacent sea of the Sundarbans mangrove forest of Bangladesh. The examined specimens were identified and diagnosed based on their morphometric characters and DNA barcoding COI gene. The new records of Pomadasys guoraca and Plectorhinchus macrospilus from Bangladesh greatly extend their distributional range in the Bay of Bengal. An updated checklist of grunts of Bangladesh is provided.

The study was conducted from March to October, 2014. A total of 56 species of fishes have been recorded belonging to eight orders, 21 families and 37 genera. Cypriniformes was the most diversified fish group in terms of both number of species and individuals observed. Among 56 species, 32 species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, three species of Channiformes, three species of Synbranchiformes, one species of Beloniformes, one species of Clupeiformes and two species of Decapoda were found. The study revealed that 32.14% of fish species were threatened. Among the threatened species, 12.5% were vulnerable, 16.07% endangered and 3.57% were critically endangered. Overall values of diversity, richness and evenness indices were found 1.42, 6.64 and 0.86, respectively. From the investigation, it was found that the fish biodiversity of the Talma River has declined day by day due to over exploitation, natural causes (such as siltation, flooding, drought and calamities), construction of obstacle for fish migration and lack of public awareness.

A total of 103 individuals were collected from four sites located at the Korea Strait (Southern coast of Korea) and the East coast of Korea and two places in the Pacific coast of Japan. For all the populations, nucleotide diversities were low (0.006 -0.009) while the haplotype diversities were as high as 0.92 to 0.97, indicating that the fish has undergone a recent population expansion after experiencing bottleneck. Star-shaped patterns of haplotype networks as well as the significant negative values of Tajima's D and Fu's F S corroborate the recent population expansion. Mismatch distribution analysis reveals that the demographic expansion of the species started during the 2 nd half of the Middle Pleistocene Series approximately 141,000 -406,000 years ago. Hierarchical analysis of molecular variance (AMOVA), the pairwise population statistics (F ST ), and the exact test of haplotype differentiation demonstrate no significant genetic differentiation among populations investigated, suggesting that spotty belly greenling is panmictic in the East Sea and the Pacific coast of Japan.

Stocking density was 6250 per decimal with a mean weight of 0.1920.002 (g). This study was done with three replications for each season. During the WS, the mean values of water parameters were temperature 16.78±2.17, transparency 32.67±1.9 cm, dissolved oxygen 5.882.18 mg/l, pH 8.240.49, total alkalinity 184.7222.72, and ammonia nitrogen 0.210.05 whereas the mean value of water parameters in SS were temperature 30.56±1.51, transparency 30.61±1.71cm, dissolved oxygen 4.31.37 mg/l, pH 8.330.24, total alkalinity 274.956.73 mg/l, and ammonia nitrogen 0.160.05 mg/l. Mean values of survival and specific growth rates were 58.940.95 and 2.450.03 in WS and 67.854.27 and 4.001.03, in SS respectively. Mean gross and net productions in WS were 1581.9471.55 kg ha -1 60 d -1 and 1285.0369.84 kg ha -1 60 d -1 and, 4262.74147.81 kg ha -1 60 d -1 and 3964.74145.74 kg ha-1 60 d -1 , in SS respectively. Therefore, it can be concluded that mirror carp fry production was better in SS than in WS.

Fishes were reared in bamboo framed net cages under three different stocking densitiesina single experimental culture cycle of 4 months (July to October, 2013). The experimental earthen pond at Sher-e-Bangla Agricultural University (SAU) campus, Dhaka, was installed with a total of nine 1m (1m x 1m x 1m) cages; wherein 100 fish m , 150 fish m and 200 fish m were 3 3 3 3 3 2
