Functional ingredients and additives promote growth, improve health of farmed shrimp, and bolster immune response and other physiological needs.
Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems.
Effective aquafeed management methods are critical for efficient production of farmed shrimp, and to minimize environmental impact. In the second part of his series, Editor Emeritus Darryl Jory looks at shrimp feed management in terms of application, distribution, frequency, calculations
Assuring that aquafeed ingredients are processed properly into a high-quality product requires monitoring each manufacturing process through the proper in-line quality assurance, to produce a consistent quality continuously.
The methodology used in a Texas Agricultural Experiment Station study provided a useful tool for evaluating the attractiveness of individual ingredients in prepared shrimp feeds.
The process for making extruded shrimp feeds has flexibility to produce diets with a wide range of fat levels, densities, shapes and sizes.
"New" ingredients like seaweed meals, particularly from various kelp species, provide trace minerals and vitamin A, and increase the palatability of shrimp feeds.
New ingredients and processes are figuring prominently in the production of more-nutritious and better-balanced “specialty" shrimp feeds.
Synthetic and natural binders that provide increased water stability are often used without consideration of the final dry or wet pellet texture of the shrimp feed.
