Abstract

Aims research to know the best substrat type for increasing the density of the maggot population. This research was conducted on December 23rd to January 22nd, 2014, at Hatchery and Aquaculture Technology laboratory Cunda, Lhokseumawe. Experimental methods was Complete Random design (CDR) non factorial with 5 treatments and 3 replication. The results showed the best treatment with combination of dregs tofu, dregs coconuts, bran and pal oilcake with the average value of the density of population of maggot 4.60 ind/cm3, weights 190 grams, and a length of 1 cm. Experimental needs to be done further Suggestions to look at other types of media to increased the population density of the maggot.

Abstract

The study aimed to determine the effect of formulated feed from different vegetable sources onto growth of gouramy fingerling (Osphronemus gouramy). The method used a non factorial completely randomized design with five treatments and three replications, namely A: commercial feed (control), B: formulated feed of Moringa, C: formulated feed Gliricidia, D: formulated feed ofCentella asiatica and E: formulated feed of three vegetable mixture. The results showed that formulated feed from different vegetable sources gave highly significant effect on growth of length (1,025± 0,126 cm in average) and weight1,133 ± 0,212 gram in average), feed conversion ratio (6,96±0,32 in average)and the response of fish to feed (25,61±0,65 minutes), which was Fcount > F table. The highest value on growth and feed conversion ratio was obtained in treatment B, whereas, the best response of fish to formulated feedwas obtained in treatment A (commercial feed). Furthemore, formulated feed also provided survival rate of gouramy (Osphronemus gouramy) relatively well.
