Feed for thought: Shrimp feeds

Rizky Darmawan, Director, PT Delta Marine Indonesia

PT Delta Marine Indonesia in Sumbawa has 30 grow-out ponds, with sizes ranging from 3,300m2 – 5,000m2, and 7 treatment ponds. It has a target of 500 tonnes/year. Typical with farms in Indonesia, the stocking density is 120-180 PL/m2 with post larvae (PL11-13). We focus only on grow-out and ideally, will partial harvest a few times, starting at size 70/kg and the final at size 20/kg. Days of Culture (DOC) is 50 days for 70/kg size to DOC120 at final harvest. In our final analysis on cost of production, feed cost accounts for 50-60% of the direct costs. Feed conversion ratios can range from 1.2:1 to 1.5:1 depending on culture conditions. As a farmer, I do not wish to see my FCR climb to 2:1 and prefer to manage my ponds well to maintain an optimal FCR.

The right choice of feed and feed management throughout each cycle is very critical as this can affect the ADG and can make or break the cycle. We have set the rules on choice of feeds and select feed based on consistency for quality and performance, i.e. to be able to deliver the average daily growth that we have structured into our cost and is competitively priced. We also benchmark feeds so that we can see relative growth performance.

In terms of feed management, there are certain practices in Indonesia that are not applied elsewhere. The Feed Index is (± 0.55) is calculated as: Feed/PL Count x 100,000 / DOC. As we feed using auto feeders, there are some feed specifications that are important to us, such as with starter feeds. As a user of feeds, I have hopes and dreams on specifications for the feeds to be used at each stage of the production cycle, for the final harvest quality as well as for disease interventions and conserve the pond environment.

In this presentation, I will walk the feed industry through with my choice of feeds, standard operating procedures, the dos and don’ts in feed management, and constraints at the farm levels. The aim is to show formulators how feeds interact with culture practices at my farm.
