Abstract:
Carps account for roughly 90% of production in inland aquaculture and constitute the backbone of Indian fisheries. The development of feeding technology is crucial for the expansion of a target species' aquaculture activities. Larval nutrition has gained more attention in the last few years. It is clearly evident that common carp larvae show a great tendency towards zooplankton but will also readily ingest floating supplementary or balanced feeds if the particle size is small enough to swallow one of the causes of larval mortality is a lack of the proper kind and amount of live food. It has already been proven that plant-based components can substitute fish meal in the diet. Native to the Indian subcontinent, guar is an annual herb that may grow up to 2 meters tall. It is mostly grown for its endosperm, which contains galactomannans, and for its by-product, which is a valuable component of animal feed. The purpose of the current study is to evaluate the effectiveness of guar meal as a suitable feed ingredient, to determine the commercial viability of such a substitution, and to provide some preliminary observations about guar meal's suitability for the aquaculture business. The experiment utilized a completely randomized design (CRD) with five treatments (0%, 10%, 20%, 30%, and 40% guar replacement) (including one control). Treatment means were compared with the post hoc test and Duncan‘s multiple range test. All the growth parameters recorded show an increasing trend up to 30% replacement, which indicates that the effective replacement of soy meal by guar meal up to 30% does not have any significant effect on the growth and survival of common carp larvae. Thus, we recommend that soy meal can be effectively replaced by guar meal up to the level of 30%.
