Flesh Estimation of Some SIS Fish

Abstract

Small Indigenous Species (SIS) of fishes of 18 species under ten families and five orders were selected for the experiment. The percentage and ratio of edible portions compared to their wastes (%) were determined. The percentage by weight after dressing and washing was found for Corica soborna as 97.76% and the lowest for Colisa fasciata as 57.40%, but the ratio of these weights were maximum on C. fasciata and minimum in C. soborna.

Human Perceptions about the Himalayan Brown Bear and other Carnivores in Chitral District in the Hindu Kush Range, Pakistan

“…In our study, the observed maximum length of C. soborna was 5.0 cm TL irrespective of sex, which is higher than the reported value of (i) 2.70 cm (Sultana, 2012) from the Ganges River, Bangladesh (ii) 4.99 cm (Hossain et al, 2008) from the Mathabhanga River, Bangladesh (iii) 3.80 cm (Kamal, 1982) from the Ganga River, India, but lower than the maximum recorded length (TL= 5.3 cm) reported by Hossain et al (2017a) from the Ganges River, NW Bangladesh. Information on maximum length is crucial for the estimation of asymptotic length and growth coefficient of fishes, as required for planning and management of fisheries resources (Hossain et al, 2012a(Hossain et al, , 2017d(Hossain et al, , 2018Hossen et al, 2018;Khatun et al, 2019a).…”

Feeding ecology of a bagrid catfish,Mystus tengara(Hamilton, 1822) in the Tanore wetland of Rajshahi, Northwestern Bangladesh

“…Small indigenous species (SIS) thrive well in freshwaters and can be grown easily in fallow water areas and marginal wetlands in the vicinity of agricultural lands, roads and houses where larger fish species cannot survive (Sultana, ). Therefore, the extensive culture of this species does not require much consideration and can be based on selected food items available in nature.…”

Minerals and fatty acid profile of small indigenous fish species from homestead ponds within a Sub-tropical coastal region

“…Both natural events and human-induced disasters have contributed to the degradation of aquatic ecosystems in Bangladesh, leading to the loss of conducive environments for SIS. As a consequence, SIS are facing severe threats, and are at a critical risk of extinction [ 11 ]. In earlier times, SIS were considered as weed fish and were removed from the culture ponds using chemicals and pesticides (rotenone, benzene hexachloride, saponins, calcium cyanamide, sodium cyanide, chlorine, calcium hypochlorite, sodium pentachlorophenate, and lime etc.).…”
