The gonadal maturation of climbing perch, anabas testudineus (Bloch, 1792) with dietary supplement add on feed

Fish use the food supply for energy and gonadal maturation, which can be optimised by addition of supplement in the form of vitamin C, vitamin E and Spirulina sp. This research was carried out to examine the impact of additional supplement on the level and index of gonadal maturation, diameter of ovary, fecundity and the successfulness of hatching on female parents of climbing perch (Anabas testudineus). There were 27 fish parents cultivated in nine ponds for three months from April to June 2017. The broodstocks were fed with the commercial pellets as much as 3 of fish biomass. For treatments, the pellets were added with the supplement of vitamin E and vitamin C i.e 0.1 each, as well as Spirulina sp. i.e. 3 in dosage. The experiment was set on completely randomized design with three replications. The results showed that the addition of Spirulina sp. had a significant impact on the index of gonadal maturation as well as the increase of body and gonadal weights. Meanwhile, vitamin E significantly affected the fecundity and the ovary diameter. There was no significant effect of vitamin C on all parameters. © 2020, BIOFLUX SRL. All rights reserved.
