“…The RLG appears to decrease with increase in body length in R. daniconius (Wijegoonawardana, 1990), and it does not seem to change much with increase in body length in D. aequipinnatus and B. sarana (Wijegoonawardana, 1990). Parameswaran et al (1970) and Abujam et al (2013Abujam et al ( & 2014) found that the food and feeding habits changes as they grow into adult of N. nandus and spiny eels. Interestingly, this variation was noticed in both young and adult fish, thus ruling out any substantial change in diet.…”

“…The occurrence of low feeding in other fishes coincide with their peak breeding was reported by several workers (Fatima andKhan, 1993 andSerajuddin et al 1988). The high feeding intensity in spiny eel (M. pancalus & M. aral) was recorded in early maturity and was relatively lower in ripening of the gonad (Abujam et al, 2013(Abujam et al, & 2014.…”

The feeding habits of Esomus danrica was carried out from the Maijan wetland and fish landing sites at Guijan Ghat of Brahmaputra River, upper Assam. The lowest relative length of gut (RLG) of E. danrica was found as 1.24 (± 0.52) in >5 cm group whereas the highest as 1.6 (± 0.7) in 4-5 cm length group. It reveals that the fish falls in the category of carni-omnivorous fishes. The gastro somatic index (GSI) ranged from 1.799 ± 1.396 (Dec) to 6.499 ± 2.690 (Apr) for males and from 1.81 ± 0.700 (Nov) to 5.960 ± 1.497 (Apr) for females. In male, the minimum GSI (3.31 ± 1.7) observed in immature stage and maximum (5.14 ± 1.04) in mature stage. In case of females, the minimum (2.4 ± 1.1) and maximum (4.55 ± 1.3) were recorded in maturing and ripe stage respectively. The active feeding was recorded during November (66.7%), moderate feeding during May (61.8%), while poor feeding during August (48.6%). Empty stomach was also recorded throughout the year with little percentage. Again, the highest active feeding (41.1%) was recorded in ripe species; moderate feeding (47.4%) and poor feeding (25%) in mature and immature stage respectively while the highest percentage of the empty stomach (25%) was observed in immature.

“…Dakua et al (2015Dakua et al ( , 2016) studied on length-weight relationship of Esomus danricus and Parluciosoma daniconius from upper Assam. Feeding habit and length-weight relationship of the freshwater spiny eel from the upper Assam were investigated by Abujam et al (2013 and Biswas (2014, 2016). Due to their colour, size and playful behaviour, they are highly rated as aquarium fish in the region.…”

Abstract:The investigation has been carried out from different landing site of the Brahmaputra River at Dibrugarh, Assam, India during February, 2014 to January 2015. As a whole, the relative length of gut (RLG) value was found to be highest during pre-monsoon and lowest during winter season. Among the examined species, Trichogaster fasciata was recorded as highest RLG value (5.74) and the lowest (1.10) was recorded in Mystus tengara. The value of RLG reveals that the feeding habit shows a variation from species to species. In case of gastrosomatic index (GSI), out of the examined species, Esomus danricus was found to be the highest (6.5) during pre-monsoon and Osteobrama cotio was lowest GSI (2.32) during winter season. The feeding intensity was found to be more or less similar in all the species. Again, in relation to the growth co-efficient 'b' of all the examined species, Puntius sophore was recorded as highest 'b' value (3.31) during monsoon while Osteobrama cotio was recorded as lowest (2.50) during winter season. Further, it predicts that the examined fish species did not follow the cube law and showed the allometric growth. The highest (1.85) condition factor (K) was recorded in P. sophore and observed in monsoon. In case of its lowest (1.0) was recorded in Salmostoma bacaila and observed in winter seasons. They were found in health and well-being condition and calculation of growth coefficient. After washing the specimen were preserved in 5% formalin for further study. For the study of feeding habit, length-weight relationship and condition factor, total length of the individual fish was measured from the tip of the snout to the extended tip of the caudal fin; total body weight was measured to the nearest 0.1 gm in electronic balance. Relative length of gut (RLG)The alimentary canal of the fish specimen was dissected out, uncoiled it and cleaned off the fat body and other associated gland from the alimentary canal. The extended alimentary canal was then measured in measuring scale followed by taking the weight of the alimentary canal in the electronic weighing balance. The relative gut length is calculated by using the formula of AlHussainy (1949): RLG=GL/TL, where, GL=Gut length of the fish; TL=Total length of the fish. Gastrosomatic index (GSI)GSI is calculated by taking the ratio between gut weight and total body weight of the fish specimen and multiplied by 100 (Biswas, 1993). Length-weight relationshipThe relationship between the total length and the total weight were determined by using the formula as proposed by LeCren (1951): W=aL b where, W=weight in gram; L=Total length of the fish specimen in cm; a and b is initial growth and growth coefficient respectively. To make the relationship linear,
