Fishes of Gobiidae Family, Recorded from the Rivers and Estuaries of Bangladesh: Morphometric and Meristic Studies

Abstract

The study was carried out to determine morphometric and meristic characteristics of fish species belonging to Family: Gobiidae, and examined 42 specimens were collected from rivers and estuaries ecosystem in Bangladesh during January and February, 2015. Samples were found in fresh to brackish water and muddy habitats of estuary areas at Nijhum Island, (Hamilton 1822) and Boleophthalmus boddarti (Pallas 1770) have been studied and comparatively described. This paper discusses the diagnostic characteristics of these fishes. Hatiya; junction of Meghna River and Bay of Bengal, and also recorded from Pasur River is near the Sundarbans in Bagerhat. Morphometric and meristic characteristics of Taenioides buchanani (Day 1873); Odontamblyopus rubicundus (Hamilton 1822); Trypauchen vagina (Bloch and Schneider 1801); Pseudapocryptes elongates (Cuvier 1816); Scartelaos histophorus (Valenciennes 1837); Apocryptes batoBangladesh J.

Estimation of Population Parameters of Glossogobius giuris in the Rabnabad Channel, Southern Bangladesh: Implications for Sustainable Management

“…Out of the 18 gobiid species so far recorded in Bangladesh [13], the majority do not constitute an important fishery because of their small size and low consumer demand and market value. But G. giuris, which grows about a foot in length and has consumer demand and high market value, remarkably forms a fishery of some magnitude in the southern part of Bangladesh [14]. Therefore, this fish is caught in large quantities in both subsistence and artisanal fisheries in this area, including Rabnabad Channel.…”

“…Numerous studies have been undertaken on this species from its major distribution areas, such as ecology and ecosystems [16][17][18][19][20][21], food and feeding habits [22][23][24][25][26][27][28][29], size relationships and growth [30,31], reproductive traits [14,16,22,24,28,[32][33][34][35][36], and stock assessment [37]. However, there is no research on population parameters (e.g., reproduction, recruitment, growth, and mortality) of this species in Bangladeshi waters, which would help to estimate the maximum sustainable yield (MSY) and formulate fisheries management approaches for the resources [38].…”
