Earthworms have known as one of the live food which can provide the good reproductive performance on fish broodstock, whereas there are many other types of live food which is also considered potentially include maggot. Research about the use of maggot meal and earthworm meal ratio to improve reproductive capacity on Kurumoi rainbowfish broodstock was conducted. The research was conducted in male and female broodstock and were paired as two pairs in an aquarium (3-5 g, 6-7 cm, ± 5 months of age) during 4 months of observation. Tests carried out with the use of maggot meal (MM) and earthworm meal (EM) ratio with treatments as follows: A (0% and 100% EM MM), B (25% and 75% EM MM), C (50% MM and 50% EM), D (75% MM and 25% EM) and E (100% and 0% EM MM). Each treatment was four replicates. Fishes were fed 3 times daily at 08.00, 12.00 and 16.00 in satiation. Sampling was done every month to measure of weight and length. Other parameters such as the spawning intensity, the number of larvae performed incidental (direct current events) with daily observation, larvae were observed and separated in another container after hatching. The results showed that there was no significant difference as statistically between each treatment using analysis of variance and Tukey test on weight, length and survival rate parameters both in females and males (P>
0.05) except the final weight of males (P <0.05). The intensity of spawning that occurs typically 4 to 6 times per month, which means that one or less than one week occurs of continuous spawning (partial). The average of larvae number in each replication showed a significant difference on each treatments where the use of 100% maggot meal ratio (E) was the highest, while the use of 50% maggot meal and 50% earthworm meal ratio (C) was the lowest.Pages: 43-52 | 226 Views 35 DownloadsDownload Full Article:
