Fish constitutes almost half of the total number of vertebrates in the world. Our country occupies 9th position in terms of fresh water mega biodiversity. The surveyed on fish diversity of Pumlen Lake in Manipur were carried out during January to December, 2012. A total of 40 species of fishes belonging to 27 genera, under 14 families and 7 orders were reported during my study period. Order Cypriniformes with maximum number of 22 fish species followed by Perciformes with 7 fish species and order Beloniformes with only 2 fish species. Of these, the most abundant is Channa puntata (6.39%), Tilapia mossambica (6.12%) followed by Amblypharyngodon mola (5.84%) and Glossogobius guiris was least abundant (0.33%).

They are an almost zero-carbohydrate food, good for diabetic and other such patients1. The values of the Log C are 1.7189 and n is 1.5573 for Labeo calbasu. Calculating the LWR for the both fishes it was found that growth fish population from the data it could be concludes as allometric in nature. The study presents valuable data for fisheries scientists. The predictive equation can be used to estimate parameters investigated with a fair amount of accuracy within the size range studies. INTRODUCTION Basic information, such as, knowledge on parameters that relate weight to length of fish is scanty, even though it is of great importance in studies on fisheries biology and on the evaluation of fish stocks. Among its most frequent uses, the importance of length-weight relationships (LWR) in the calculation of the fish average weight at a certain length class and the conversion of an equation of growth in weight, besides morphological comparisons between populations of the same species or between species. LWR is of great importance in fishery assessments. Length and weight measurements can give information on the stock composition, life span, mortality, growth and production. The results obtained from this study will be useful to fishery biologists. This relationship serves three purposes, viz., (a) to determine the type of the mathematical relationship between two variables; so that, if one variable is known, the other could be computed; (b) the relative condition could be estimated to assess the general well-being of the fish and type of growth, i.e. whether isometric or allo-metric; (c) it helps to estimate the potential yield per recruit in the study of fish population dynamics. Such relationship for the fishes could be valid when the fish grows isometrically.

Biodiversity is the total variability within all living organisms and environmental complexes they inhabit which includes diversity of form right from molecular level through individuals, populations, communities, ecosystem, landscapes and biosphere. Manipur the " Jewel of India or Switzerland of the East " has peculiar features like endemic plants, animals and scenic beauties. Our Loktak Lake is one of them. The cultural and traditional aspects of Manipuris will never completed without relating to this Lake, which also witnessing the whole history of Manipuris civilization. Lake is very important in terms of its socioeconomic value, environment, cultural, tourism, habitat of various plants, animals, fishes and potential natural resources etc. The Lake is only freshwater body in entire NorthEast India which is also commonly called as floating Lake in the world due to its floating Phumdis (heterogeneous mass of vegetation, soil and organic matters at various stages of decomposition) on it, is located near Moirang. This region represents an important part of the Indo-Myanmar biodiversity hotspot, one of the 34 global biodiversity hotspots recognized currently. But today the condition of the Lake is very worse in the field of various features like plants, animals, fish resources in present context. Our research work is trying to high light the check list of fish species of Loktak Lake in present scenario and its management and conservation aspect. During our investigation we had come across 48 different species of fishes under 5 order 17 family 33 genera. Out of these 28 fish species are available throughout the year and 20 fish species are available during rainy season only. A fish species called as Esomus altus (Lameithanbi or Belunpaibi in local language) is very rare and new record from India. One important finding during our research is that a fish species called as Channa punctatus (locally called as Ngamu Bogra) were disappeared during 1990s due to Epizootic Ulceric Disease Syndrome. But today this species is readily available in the Lake again. The present paper also shows a huge declining in species abundance as compared to earlier days, may be due to physicochemical properties of water, human civilization etc. it is right time to make proper policies and needful action as well as implementation so that the next generation could get the fish lively on the globe rather than Google, photographs, and on the literature of any paper or books.

Survey was conducted during January 2012 to December 2014. Information was collected through participatory rapid appraisal covering the entire lake and four fishermen villages, viz., Tokpaching, Chingjao, Nongmaikhong, Komnao, and Kakching Khunou Thongam. Study indicated that various types of local indigenous traditional fishing gears are used by fishers for commercial exploitation of the lake. Wooden boats (locally called as`Hi', or`Hijao') were used in fishing. These boats are small and light and prepared locally by fishers. Gill net and cast net were the main gears and contributed more than 80% of the total fish catch of the lake. Indigenous fishing gears comprising gill nets, cast nets, traps, etc., have been discussed showing their module operation. The paper also highlight that the variation in population density of the entire aquatic organism and its effect of using traditional type and modern type of fishing gears on fishing technology.

It is therefore necessary to know the length weight relationships of fish which are captured in a given place and given time. Information of the length-weight relationships of Labeo rohita and Labeo gonius is scarce hence this study conducted for the purpose of establishing the length weight relationship of these two fish species from Sone Beel, Karimganj Assam India. The values of the Log C and n are 0.3491 and 1.2159 respectively for Labeo rohita while those of Labeo gonius are Log C and n 1.2343 and 0.4297 respectively. The length-weight relationship of a fish is basically a measure of its growth pattern and or age. It also helps to evaluate the condition, reproduction history, life cycle and the general health of the fish species. The study presents valuable data for fisheries scientists and other researchers.
