P. Vanamei Shrimp Post Larval Feed Shrimp Larvae Feed

P. Vanamei shrimp Post-larvae Feed

• Microparticulate feed that offers superior buoyancy and availability in the water column for early stage shrimp larvae
• A complete nutritional profile designed to compliment live Artemia nauplii feeding
• Selected high quality marine ingredients with full balanced nutrition
• Formulated to provide color-staining of the gut

• Significantly increases growth and improves survival rates

Practical feeding regimes
The natural feeding habits of shrimp are replicated in hatcheries using different species of microalgae, zooplankton — mostly Artemia and formulated feeds. Algal feeding is done once or twice daily to maintain the desired algal cell density. Amounts of dry feed gradually increase over time.

Feeding behaviour moves gradually from filter feeding in zoea to hunting in mysis so it is good practice to provide heat-killed or frozen Artemia instar 1 stage nauplii from late zoea up to PL1 before using live Artemia. In general, from PL5 onward, no more Artemia is needed with only formulated feed being fed.
Nutrition Formulated feeds have similar composition to microalgae and zooplankton with high levels of essential nutrients such as vitamins, astaxanthin, n-3 highly unsaturated fatty acids (HUFA), cholesterol and lecithin. Good quality feeds use highly digestible raw materials with good nutritional value such as meals and oils of marine origin, hydrolyzed proteins, yeast and algal meals. Lipids play a key role in shrimp development, supplying building blocks and energy for maintenance and growth. Some lipids cannot be synthesized to required levels by shrimp e.g. cholesterol, phospholipids and sterols which need to be provided by the diet. Fat-soluble vitamins as well as carotenoids are also essential for shrimp larvae and postlarvae. Lipid requirement is highest in zoea stages and lower in PL and juvenile stage.

The optimum protein level in a larval diet varies with stage, protein source, digestibility and amino acid composition. Zoea protein requirement of 30% increases to 50%–60% for mysis stages and decreases to 40% in PL’s. Water-soluble vitamins are essential for all shrimp stages and need to be included in diets to optimise growth and development and — in particular with vitamin C — to maximise resistance to stress and diseases. Shrimp larvae do not appear to require carbohydrates in the diet with energy obtained from lipids and proteins. Carbohydrates are often included in larval feeds as binders.
