this research was carried out to define the morphological features of meckel’s diverticulum (md) induck and to investigate whether the md resides in a constant position along the intestinal tract. for thispurpose, a total of 30 adult healthy ducks of both sexes, 50-52 weeks of age were used. after dissecting,some morphological factors such as: total intestine length as well as the lengths of th...

A 75 days feeding trial was conducted to evaluate the influence of dietary supplementation of multi-strain (Bacillus sp.) probiotic (22×109 CFU/g) on growth and hematological parameters of Barbonymus gonionotus. A total 270 uniformed size (length 2.40±0.16 cm and weight 4.25±0.01g) fishes were equally and randomly distributed in nine (three treatments each with three replication) glass aquaria ...

The relationships between sagitta otolith morphology and fish size were examined for common carp in the Southern Caspian Sea and also the aging of different length groups were determined. Statistical tests to examine correlation between left and right otoliths dimensions were carried out and no statistically significant difference between them was found. The biggest otolith had 0.032g weight be...

mehg and total mercury concentrations were determined in the muscle tissues of four fish species (cyprinus carpio, rutilus frisii, carassius auratus and esox lucius) from anzali wetland (guilan, iran). fish with the highest amount of mehg was selected to determine the thermodynamic parameters of mehg extraction. the extractions process was performed in the range of temperatures 331.15 to 367.15...

Neotropius atherinoides locally known as Batasi fish and considered as freshwater small indigenous species (SIS) in Bangladesh. The present study describes the first complete, inclusive description of length-weight relationships (LWRs), length-length relationships (LLRs), condition factors (Fulton’s, KF; Relative, KR) and the breeding biology in the adjacent river of Chalon beel, Bangladesh. Th...
