How to choose food for shrimp larvae

Larvae of shrimp brookstock feeds include a variety of larval stages, such as algae, dry algae, synthetic feeds, processed foods, artemia, rotifers. Replacement of partial replacement or replacement of all natural fresh foods (AP0 Frippak, No, Lansy, Dry Algae). However, it is advisable to combine natural feed with synthetic feed and dry algae to feed the larvae.

Fresh algae are required feed ingredients during Zoae 1 – Zoae 3 and are maintained until the end of the Mysis period. Fresh algae provide important nutrients and trace elements during the development of shrimp seed. Fresh algae of suitable size suitable for the mouth of shrimp larvae from Zoea to Mysis stage.

Artemia is a very important food for rearing larvae and post larvae, because it is rich in nutrients, contains high levels of unsaturated fatty acids and easy-to-digest protein, Artemia larvae move slowly, small size suitable for shrimp larvae . Use Artemia when the larvae reach the Mysis 1 stage or possibly from the Zoae 3 stage. To produce 1 million Post 10 – Post 12 larvae, 3 to 4 kg of Artemia Artemia eggs must be used. Choose artemia with a high hatch rate, evenly, small in size.

Food composition of shrimp larvae
At the time of Nauplius, the larvae fed the yolk diet did not need to be fed. At the end of the Nauplius period, fresh algae were fed to the larvae at about 100 liters per 1,000,000 larvae.

The Zoea stage, the feed ratio of each company varies, but fresh algae are always the main ingredient (60-80%); Dry algae accounts for 10%; Compound food accounts for 10 – 30%. Composite feed: 40% Frippak + 20% Lansy + 20% V8-Zoea + 15% No + 5% ET 600. The amount of fresh algae used in the Zoea 200-300 liter algae / Density of algae, Chaetoceros density 106, Thalassiosira 105 densities. In Zoea 1, the amount of dry algae was 8 – 10 g / 1,000,000 larvae / day. Combined feeds of 20-30 g / 1,000,000 larvae / day. Into the Zoea 2 stage, the amount of dry algae 10-12 g / 1 million larvae / day. Stage Zoea 3, dry algae 13 – 17 g / 1 million larvae / day, synthetic feed 40 – 50 g / 1 million larvae / day. At the end of the Zoea 3 stage, Nauplius Artemia was added to the diet with 50 g / 1,000,000 larvae / day.

Mysis stage, reduced fresh algae to 100 liters / 1,000,000 larvae / day, 8 feeds / day, 4 mixed feed and 4 Artemia use. The amount of feed for 1 million larvae at each stage is as follows: Mysis 1 stage, using 100 g of synthetic feed and 80 g of Artemia paring. Mysis 2, using 120 g of synthetic food with 100 g of Artemia parachute. Mysis 3, using 140 g of synthetic food with 120 g of Artemia parachute. Combined feed includes: 30% Frippak + 20% Lansy + 25% V8-Zoea + 20% No + 5% ET 600. From this stage, And vitamin C with 1 ppm in feed.

Into the Postlarvae, the feed consists of: 30% Frippak + 30% Green Flake + 40% No. It is recommended to use Artemia after hatching (Nauplius artemia) and remove the shell to ensure hygiene in nursing environment. After each transition, the amount of Artemia and industrial feed per 1,000,000 larvae increased from 20 to 40 g. The amount of food for 1,000,000 larvae over the Postlarvae period is as follows:

In the nursing process, feed intake should be observed and adjusted according to the nutritional needs of the larvae.
