Session 5 Managing Productivity – Survival Rates & Disease Control
Presentation Precision Nutrition And Health Solutions For Higher Productivity

Abstract:

Driven by a need to manage the productivity in shrimp farming, optimized nutritional solutions have been developed to address the various challenges through feed and feeding. Besides the genetic potential of shrimp and optimal farming conditions, dietary nutrients in feed for shrimp can influence production efficiency. Recent studies have shown how a well-balanced supplemented diet with specific nutrition and health solutions can contribute to the overall improvement and increase of farm productivity and profits.

Maximizing feed efficiency: One of the significant milestones the industry has achieved is the successful substitution of fishmeal in shrimp feed formulations. Plant-based protein sources have shown to be a suitable replacement for fishmeal in shrimp diets. Nevertheless, the former also contain some anti-nutritional compounds, which cannot be digested or impair the digestion process of aquatic animals. It is widely recognised that the use of exogenous enzymes in aquafeed can increase the aquaculture value chain resiliency towards raw material price volatilities and supplies while minimizing environmental impacts.

Improving performance: Many shrimp farmers, particularly the large and more integrated farms in Asia-Pacific, use nurseries as part of their overall production strategy. Poor water quality and crowding can greatly increase stress levels, impact growth rate, weaken immunity, and increase shrimp mortality. At this stage, optimal nutrient requirements are higher than published levels to maintain rapid growth, health and uniformity in juvenile shrimp, before being transferred to the grow-out ponds.

Better survival: Feeding diets supplemented with health solutions  to shrimp is becoming a common practice to enhance health and stress resistance during the rearing period. Health solutions with antimicrobial, immunomodulating, and antioxidant properties show positive effects on performance, gut health, immune response and prevention against disease pathogens.  Therefore, culture can continue to market size with good survival rates and high harvest yields.

Overall, a combination of  proper management practices in feeding, farming and disease prevention must be applied to ensure a successful crop and maintain profitability.
