An experiment was conducted for 140 days in earthen ponds to evaluate the effect of three dietary protein levels on the growth and maturity of bagrid catfish Mystus gulio. Three different iso-caloric feeds containing 30%, 35% and 40% dietary protein levels were prepared from indigenous fish feed ingredients and were fed to Mystus gulio at the rate of 5% of total body weight of the fish. The ove...

The tongue-bite apparatus and its associated musculoskeletal elements of the pectoral girdle and neurocranium form the structural basis of raking, a unique prey-processing behaviour in salmonid and osteoglossomorph fishes. Using a quantitative approach, the functional osteology and myology of this system were compared between representatives of each lineage, i.e. the salmonid Salvelinus fontina...

Quantification of anatomical and physiological characteristics of the function of a musculoskeletal system may yield a detailed understanding of how the organizational levels of morphology, biomechanics, kinematics, and muscle activity patterns (MAPs) influence behavioral diversity. Using separate analyses of these organizational levels in representative study taxa, we sought patterns of congru...

The present study was conducted to observe morphological and histological changes in the developing digestive system during the ontogeny of featherback, Chitala chitala (Hamilton), from hatching to 30 days post hatch (dph). Three significant stages were identified during digestive tract development in featherback: (1) endotrophic (0-8 dph), (2) endoexotrophic (8-12 dph), and (3) exotrophic (12-...

Notopterus chitala is a member of the primitive teleost lineage and considered as commercially important food fish. To study concentration sodium potassium influence fish size condition factor on bioaccumulation these macro-elements, total 16 specimens N. were collected from River Indus. Mean (±SD) body weight, length was found 250.32±113.93 g, 32.93 ± 4.85 cm 0.647± 0.094. Fish samples oven dr...

the disposition and cellular organization of the endocrine pancreas were studied in three species of freshwater teleosts viz., labeo bata (hamilton, 1822), sperata aor (hamilton, 1822) and chitala chitala (hamilton, 1822) using histological techniques. in l. bata, the endocrine pancreas tissues were mainly distributed in the adipose tissue among the intestinal coils and adjacent to extrahepatic...
