Total weight of the sampled fish varied from 22 to 171.50 g and length varied from 16.50 to 33.0 cm. Dominance of female over male was observed in the species. The ratio of male to S. Banik female was 1:1.65. Significant correlation was exist between fish length and weight in both males Department of Zoology, (R²=0.943) and females (R²=0.827).

  • Ichthyofaunal Diversity of Jinari River in Goalpara
    CIBTech Journal of Zoology ISSN: 2319–3883 (Online) Online International Journal Available at http://www.cibtech.org/cjz.htm 2020 Vol.9, pp.30-35/Borah and Das Research Article [Open Access] ICHTHYOFAUNAL DIVERSITY OF JINARI RIVER IN GOALPARA, ASSAM, INDIA Dhiraj Kumar Borah and *Jugabrat Das Department of Zoology, Goalpara College, Goalpara, Assam, India, *Author for Correspondence: [email protected] ABSTRACT The present study attempts to access the ichthyofaunal diversity of Jinari river in Goalpara district of Assam, India. There was no previous report on piscine diversity of this river in Assam. Survey was conducted in the lower stretch of the river in Goalpara district from April 2018 to March 2019. Fish specimens were collected from five pre-selected sites, preserved and identified adopting standard methods. A total of 74 fish species belonging to nine (9) orders, 26 families and 58 genera were recorded. Cypriniformes was the dominant order with 35 species followed by Siluriformes with 19 species. IUCN status shows two vulnerable, eight near threatened and 66 species under the least concern category. Prevalence of anthropogenic threats like garbage dispersal and agricultural pesticide flow to the river, setting of brick industries on the bank, poison fishing in the upper stretch etc. may affect the fish population in this river. In this regard, awareness is the need of the hour among the inhabitants of the surrounding villages. Keywords: Ichthyofauna, Jinari River, Goalpara, Brahmaputra River, Assam INTRODUCTION The Northeastern region of India is considered to be one of the hotspots of freshwater fish biodiversity in the world (Ramanujam et al., 2010).

Haque Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh 2202, Bangladesh 1Ptresent address: Bangladesh Fisheries Research Institute, Riverine Station, Chandpur 3602 *Corresponding author Abstract Baseline survey and Participatory Rural Appraisal (PRA) during January 2003 to December 2004 on the fishing community revealed that unregulated fishing, use of destructive fishing gears, poaching of fishes, difficulties encountered in enforcing fisheries regulation and the helplessness of fishers to find alternative sources of income during banned fishing period (June to October) were the major management problems. CBFM (Community Based Fisheries Management) system as an alternative management strategy has been introduced to ensure active participation of the target group-the poor fishers living around the beet who were previously deprived to get access to the beet. Establishing a leasing system for controlled access, ensuring greater user-group participation through equitable distribution of all resource benefits among members, attempting to enforce penalties for illegal fishing linked with surprise checks to enforce management regulations are some of the recent steps taken by the BMC (Beet Management Committee). Chapila fish intake by the community was 31.25 g/head/day before stocking the beet by carp fingerlings. After stocking, they consumed chapila as fish protein from 8.33 g to 20.8 g/head/day during the fishing season (November to May) indicating that due to introduction of carp fingerlings, chapila production has been decreased in 2003-2004.

    Iranian Journal of Fisheries Sciences 17(3) 458-470 2018 DOI: 10.22092/IJFS.2018.116612 Gonadal maturity assessment of butter catfish (Ompok bimaculatus) from major rivers and tributaries of India during spawning season Mishra A.1*; Sarkar U.K.2; Kumar R.3; Rawat A.4; Verma S.5 Received: September 2015 Accepted: January 2017 Abstract The present work focused on exploring reproductive biology of fish from different major rivers of India and their tributaries by comparing ovarian protein, fecundity, oocyte weight, oocyte diameter and condition factor during the spawning period. Significant correlation was found between reproductive parameters of fish in the major rivers and their tributaries. Among the parameters studied fecundity showed the highest correlation with ovarian protein level and oocyte weight in the major rivers, whereas in tributaries it was highly correlated with ovarian protein. The results from a wild population showed that the fecundity and ovarian protein level were significantly higher in the Narmada River, and the lowest in river Ganga (U.P.). Among the tributaries, maximum ovarian fecundity was observed in fish with the highest protein concentration from River Hooghly. The condition factor (K) in female Ompok Downloaded from jifro.ir at 14:24 +0330 on Monday October 4th 2021 bimaculatus were reported to be significantly high in the major River Cauveri and Sharda tributary. The oocyte weight was significantly higher in the major River Krishna and the lowest in fish from River Godavari. In fish samples collected from tributaries, those Sone River showed the highest oocyte diameter and fish from Betwa River showed the lowest oocyte diameter.

  • New Intervention on Pabda Cum IMC Polyculture in North Tripura District.”- KVK North Tripura
    Success Story on “New intervention on Pabda cum IMC polyculture in North Tripura District.”- KVK North Tripura Pabda is a species of catfish which is considered as a high value fish in the markets of Tripura as well as in the North Eastern Region of the country. It’s a very delicious fish and was declared as “State Fish of Tripura”. Pabda fish is a freshwater fish species. It is very tasty and has high nutrition value. So it has a great demand and high value in the market. Pabda fishes can be found mainly in the pond, swamp, paddy field etc. Pabda fish culture is considered as high value fish culture and the profit obtained from this type of fish culture is also higher than normal fish culture. The farmers of North Tripura district are mainly associated with culture of Indian Major Carps, exotic carps and few other minor carps etc. in traditional ways under normal fish culture activities. The earnings from this type of traditional fish culture practices are less compared to culture of high value commercial fish species. Keeping this in mind, polyculture of Pabda with Indian major carps appeared to be an innovative as well as high earning source of fish culture practice in this district. Intervention: An innovative approach was undertaken by Krishi Vigyan Kendra North Tripura for development of polyculture practice of Pabda with Indian major carps among the special interested groups of farmers in different places of North Tripura district. Under this activity at first beneficiaries were selected based on their interest and three numbers of training programmes were conducted by KVK among the interested farmers.

  • Ompok Bimaculatus)
    Songklanakarin J. Sci. Technol. 42 (6), 1253-1258, Nov. - Dec. 2020 Original Article Effects of temperature on growth performance and water quality in culture system of butter catfish (Ompok bimaculatus) Pyanuth Rem*, Sommai Chiayvareesajja, and Naraid Suanyuk Department of Aquatic Science, Faculty of Natural Resources, Prince of Songkla University, Hat Yai, Songkhla, 90112 Thailand Received: 19 February 2019; Revised: 11 May 2019; Accepted: 28 August 2019 Abstract To evaluate water quality and growth performance of butter catfish under temperature manipulation, 15 fish were cultured in 16 fiberglass tanks for ten weeks in three temperatures of 29 °C, 31 °C, 33 °C, and in ambient temperature as control (25.1-29.5 °C). The growth performance and water quality parameters (temperature, DO, pH, TAN and NO2-N) in culture were investigated. Water quality seemed not to be controlled by temperature but by feed consumption. DO concentration decreased (8.27+0.10 mg/l) in the 33 °C tank (P<0.05). Growth of catfish performed well in all treatments except fish in the 33 °C tank, in which the percentage weight and length gain declined (479.70+86.64% and 73.85+10.52%, respectively) (P<0.05), and both SGR and feed intake significantly decreased (2.55+0.26 %/day and 194.28+42.40 g, respectively) (P<0.01). FCR and survival were positive in every temperature exposure (P>0.05). Results reveal that the maximum thermal tolerance for growth is best in water temperature which does not exceed 31 °C. Keywords: butter catfish, water quality, growth performance, water temperature 1.
