Abstract

Seeds of humpback grouper are often nursery is the size of 3 cm, to feed for nursery use artificial feed or pellets. Feed pellets are in great demand by employers nursery, this is because the artificial feed (pellets) nutritionally complete, easy to obtain, not depending on the season, easy in giving, does not require much effort to chop up trash fish and does not contaminate the media maintenance. Obstacles often faced in the nursery humpback grouper is an artificial feeding system gradually by feeding manually little by little until the fish are fed. Feeding system requires a lot of effort and a long time, making it less practical. The purpose of this engineering is to get the technique of feeding "Automatic Feeder" on nursery humpback grouper. Goal of this engineering is to obtain SR more than 95%, the growth rate is better and the efficiency of the use of labor. The results showed that - Survival Rate (SR) maintenance by using automatic feeder of 98.25%. Daily growth of fish feed administration using a automatic feeder for 0.01965 gram / day and FCR of 1.48. In the nursery unit of humpback grouper should use tools that SR increased automatic feeder, feeding on time, not a lot of energy providers dobutuhkan feed and feed can be set so as to be more efficient and effective.

Abstract

This study aims to determine the effectiveness of the use of natural feed powder in increasing the production of juvenile fish. This research are conducted for two months ie from January to March 2013 in Hall Aquaculture brackish (BPAP) Situbondo, using four treatments with two replications: the use of artificial feed / feed larvae (control), Spirullina sp powder, Skeletonema sp powder , Chaetoceros sp powder. Maintenance is carried out for 60 days, with the frequency of feeding 4 times, namely at 6:00, 10:00, 14:00 and 18:00 pm as many as 10% of total body weight. Temperature measurement is carried out every day and other water quality measurement once every week. Parameter research / sampling carried out at D1, D20, D40 and D60 / end maintenance. Data the length and weight of the highest in the treatment of juvenile milkfish larvae feed followed treatment Spirulina sp, Skeletonema sp and Chaetoceros sp. Data highest growth rate in the treatment of feeding the larvae of 0.0093 grams / day, Spirullina sp 0.0075 grams / day, Chaetoceros sp 0.0074 grams / day and Skeletonema sp 0,0063 grams / day. Survival Rate Highest in treatment larvae feed at 99.2% followed treatment Spirullina sp, Chaetoceros and Skeletonema sp sp.. From these results it can be concluded that the microalgae Spirullina sp provide the best data than the use of other microalgae, microalgae use of powder can be used as alternative to feeding on juvenile milkfish
