During the reporting period, a total of 75 species belonging to 49 genera and 23 families were recorded. Cyprinidae was found to be dominant families with 27 species and followed by Bagridae (7 species); Cobitidae (6 species); Channidae (4 species); Siliridae, Schilbeidae and Osphronemidae with 3 species each. In terms of composition of genus, Cyprinidae have 15 genus followed by Cobitidae and Bagridae with 4 each while Schilbeidae with 3. As far as the species composition is concerned, the Cyprinidae was 30.0% followed by Bagridae (9.33%), Cobitidae (8.0%), Channidae (5.33%), Siluridae, Schilbeidae and Osphronemidae (4.0%) whereas rest of the families accounting with 2.66% and 1.33% each. According to IUCN-2015, a total of 55 species were found under least concerned (LC), 7 species were near threatened (NT), 2 species were vulnerable (VU), 4 species were data deficient (DD), 1 species as endangered (EN) and 6 species under not evaluated (NE). It is clear that Dulakhojia beel exhibit a good number of fish species.

  • One Day GI Camp North Lakhimpur (Assam)
    Report on the One Day GI Camp in North Lakhimpur (Assam) on Effective use of Geographical Indications - MUGA Silk of ASSAM by Stakeholders March 17th, 2015 Conducted by Tezpur University Intellectual Property Rights (TUIPR) Cell & Intellectual Property Rights Cell, Dibrugarh University in Collaboration with North Lakhimpur College (Autonomous College) Lakhimpur, Assam and Technical Support of Geographical Indications Registry, Chennai April 15, 2015 TUIPR/Reports/38/2012/16 Muga Silk of Assam got a Geographical Indication (GI) registration in 2007 and in 2012, a Logo for GI- Muga Silk of Assam was also registered (Registered GI applications no 55 & 384). Assam Science, Technology and Environment Council (ASTEC) is the Registered Proprietor of the GI. Surprisingly from 2007 to 2014 there were only two “authorised users” of this GI. From 2014 to date, 19 applications to become authorised users of the GI - Muga Silk of Assam have been made to the GI Registry in Chennai, of which 14 applications have been published in the GI Journals (Journal Nos 59 & 62) and 5 applications are yet to be published. The Tezpur University Intellectual Property Rights (TUIPR) Cell initiated a project to identify the key reasons for such low usage of the GI - Muga Silk of Assam. Extensive field work was undertaken in some of the areas in which “Sericulture to Production of MUGA Products” is active to understand the dynamics of the MUGA Silk value chain. The key reasons identified by Shri Arshad Hussain, JRF in the TUIPR Cell were low awareness of the significance of GI, non-availability of reliable quality monitoring systems to differentiate “genuine MUGA Silk” from “adulterated MUGA” products, insignificant oganisational support across the entire value chain including nonexistence of enforcement mechanisms in the State of Assam against adulteration and mixed products in the market place.

Three stations were sampled monthly from January 2010 to December 2011. The analysis covered individuals with a standard length ranging from 23.93 to 129.3 mm according to sampling stations, hydrological season and fish size. The preponderance index combining the numerical occurrence percentage and the weight percentage was calculated. The percentage of emptiness is 27%, fishes are the main preys consumed by Schilbe intermedius with a preponderance index equal to 64%. There was variation in diet according to the season and the specimens size. The correlation coefficient of Spearman showed that the proportions of the different foods vary according to the size of the specimens (rs = 0.42, p = 0.05).

In this paper, I review the different clades of catfi shes, all catfi sh fami- lies, and provide information on some of the more interesting aspects of catfi sh biology that express the great diversity that is present in the order. I also discuss the results of the widely successful All Catfi sh Species Inventory Project. Introduction proximately 10.8% of all fi shes and 5.5% of all ver- tebrates are catfi shes.
