Jun 18, 2019 · At present most of the aquaculture farms depend on imported feed with an FCR (Food Conversion Ratio) of 1:1.5 – 1.8. The feeding could be done by using automatic feed dispensers, or by broadcasting all over the pond. If feeding trays are employed in selected pockets in the pond wastage in feed can be reduced. Nutrient Requirements for Shrimp:
Before stocking, make sure that there are no harmful insects. If insects are found, use organic methods to remove these insects and larvae. Check whether it is harmful to other fish. In addition, temperatures within 6°F are the most suitable for the growth of juvenile shrimp. Shrimp can be raised at a rate of 12,000-16,000 per mu.
Various automatic feeders designed primarily for fish were tried in shrimp ponds adopting intensive farming operation. Automatic feeders dispense a given amount of feed at certain interval during a 24-hour period. A timing device, usually electrically activated, is an essential component of such feeders.
Jan 17, 2022 · Shrimp farming basics: Feed management and selection. As we have stated in previous articles, feed is the single most significant aspect of aquaculture, either because of its relationship with sustainable aquaculture or simply because it is the highest cost, representing up to 70% of variable costs and between 40 and 60% of total production costs, feed is the first element of production that needs to be attended and managed.

The content of crude protein in shrimp feed was 32-38%, and the fat content was 5-6%. Some enterprises produced sinking shrimp feed, but was not very successful. Feed enterprises pay great attention to the growth rate of shrimp, the feed conversion rate of shrimp farming in ponds was between 1.8:1 and 1.4:1.
Jan 27, 2020 · The placement of auto-feeders at the optimum water depth is also important for a uniform distribution of shrimp for each feeder. Field experience tell us that the best water depth range for an auto-feeder in a pond without aeration is 1.00 to 1.30 meters, while in intensive ponds with strong aeration the best range is 1.40 to 1.60 meters
