Effect of different types of feed (squid, sea worms, and trash fish) to gonad maternity and fundamental levels of Galah shrimp (Macrobrachium Rosenbergii)

Giant prawns (
Macrobrachium rosenbergii) need enough nutrients for
the reproductive process. One way to give feed which contains high
enough protein. Complete nutritional content, especially protein, can be
found in natural food. The type of natural feed used for main feeds
including squid, sea worms, trash fish. Complete nutrient content can
affect the rate of gonadal development and fecundity. (Squid, sea
worms, trash fish) on the level of gonadal maturity and density of
broodstock parents (
Macrobrachium rosenbergii). This research was
conducted by a completely randomized design (CRD) trial design. This
study used 4 replications of different types of feeding. The types of feed
given are squid, sea worms, trash fish, and pellets at a dose of 5% from
biomass/day. The parameters of observation include observation of the
level of gonad resistance, fundamentality of broodstock parent, and
measurement of water quality (temperature, pH, and dissolved
oxygen). The results showed that the administration of different types
of feed (sea worms, trash fish) had a very significant effect on the level
of maturity and had a significant effect on the probability of prawns (
M.
rosenbergii). After analysis of variance, the results of F Calculations are
greater than F Table 0.05 and F Table 0.01. The smallest significant
difference test (LSD) was obtained in P1 (Squid feed) with the Gonad
maturity rate ± 5- 6 days as much as 83 % parent and fecundity
average results of 28,846 ± 4,925.3 thousand / 45 g.
