Length-Weight, Length-Length Relationship of the Spiny Eel, Macrognathus pancalus (Hamilton 1822) sampled from Ganges and Brahmaputra river basins, India
The freshwater spiny eel, Macrognathus pancalus is an inland water teleost fish commonly known as barred or striped spiny eel found in Asia. The sampling areas were selected which are spatially and geographically different and characterized by different environmental conditions in order to elucidation of ecotype. A total 345 specimens were collected from the sampling sites during January 2008...

متن کاملGonad Histology and Gonadosomatic Index Variations during Gonadal Development of Wild Female Tenualosa ilisha
Hilsa shad (Tenualosa ilisha) is an anadromous species which has reproductive migration from the Persian Gulf to the river. Morphological properties and histological changes in oocyte of Hilsa shad in two different environments (salt water and fresh water in Khuzestan province) were studied with respect to its reproductive cycle. Twenty fish samples with average weight of 830.75±3.25 ...
متن کاملEstimation of Fecundity and Gonadosomatic Index (GSI) of Gangetic Whiting, Sillaginopsis panijus (Hamilton, 1822) from the Meghna River Estuary, Bangladesh
Specimens of Gangetic whiting, S. panijus, were collected from the Meghna estuary to estimate the fecundity and Gonadosomatic Index (GSI) during April-September, 2011. The morphometric and meristic features of the fish were measured. The co-efficient of correlations between total length and head length with other body measurements were significant (P<0.01). The logarithmic length-weight relatio...
متن کاملMonogenoids from the gills of spiny eels (Teleostei: Mastacembelidae) in India and Iraq, proposal of Mastacembelocleidus gen. n., and status of the Indian species of Actinocleidus, Urocleidus and Haplocleidus (Monogenoidea: Dactylogyridae).
Mastacembelocleidus gen. n. (Monogenoidea: Dactylogyridae) is proposed to include two species collected and redescribed from spiny eels (Mastacembelidae) in India and Iraq: Mastacembelocleidus bam (Tripathi, 1959) comb. n. (syn. Ancyrocephalus bam Tripathi, 1959) from the gills of Macrognathus pancalus (new host record) and Macrognathus aculeatus (Synbranchiformes: Mastacembelidae) from Lucknow...
