Abstract
Small indigenous fish are delicious than other fish used for food. An attempt has been
undertaken in the current study to determine the proximate composition in small
indigenous fish species of Budhi Rapti River Chitwan Nepal. The goal of the current
study is to determine the proximate composition of the five local small indigenous fish
species (Puntius ticto, Puntius conchonius, Mystus tengara, Barilius bendelisis,
Acanthocobitis botia) found in Budhi Rapti River Chitwan Nepal. Samples were
collected between January to March 2022. The samples were cleaned, gutted, dried,
and grinded to obtain a homogenized powder that was then maintained in plastic
containers for chemical analysis. Proximate analysis was performed in the laboratory
of National Animal Nutrition Research Centre (NARC). For proximate analysis
Association of Official Analytical Chemists (AOAC) method was used. Major
proximate compositions such as, moisture, protein, lipid, ash, and fiber were estimated.
Proximate compositions were found varied among the species. Protein was estimated
in Puntius ticto (54.77 %), Puntius conchonius (63.95 %), Mystus tengara (70.68%),
Barilius bendelisis (69.82), Acanthocobitis botia (67.98%) respectively. The results
show the highest moisture content in Mystus tengara (99%) and lowest in Puntius ticto
(98.17%). The Lipid content in the present study varied between 9.05 - 15.65% with
the highest in Acanthocobitis. botia (15.65%) and lowest in Puntius. chonchonius
(9.05%). The crude fiber content varied between (1.17 -7.42) with the highest in
Barilius bendelisis (7.42%) and lowest in Puntius ticto. The ash content ranged between
16.54 -24.02% with the highest in Puntius conchonius (24.02%) and lowest in Barilius
bendelisis (16.54%). Proximate analysis was performed in National Animal Nutrition
Research Centre, Khumaltar. Analysis was carried out in triplicate. These findings
demonstrate that all these fishes have a significant amount of nutrient. At the end of the
study, no significant difference was observed in moisture, but protein, lipid, Fibre, and
ash content shows significant differences. It is clear from the current study that these
SIS are a reliable supply of macronutrients, protecting both dietary and financial
security of Chitwan, Nepal.
