Overfeeding is a waste stream for aquaculture. Underwater cameras in pens help, but a company mixing hydroacoustics and machine learning has another idea.
Existing dynamic models applied to the growth of Pacific white shrimp can describe and predict feeding behavior to help farmers achieve maximum benefits.
A study that used DDGS to partially replace soybean meal as the primary protein source in diets for juvenile white shrimp found the growth of shrimp significantly decreased when DDGS replaced soybean meal.
The potential shrimp aquaculture has for significant improvements in performance through improved genetics and nutrition will not be fully expressed unless appropriate feeding methods are practiced.
For an intensive shrimp nursery, the main goal in feeding is to supply each animal the proper quantity of feed where it can be easily accessed and consumed.
Controlled by timers, automatic feeders should be placed in deeper areas of ponds and away from aerators. Overfeeding is rare during automatic feeding, and pond bottom quality is maintained through grow-out cycles.
Zebrafish offer a living model system for research in a wide variety of scientific disciplines. The Aquatic Resources Program at Children’s Hospital Boston recently identified an alternative feeding method that requires less labor.
In laboratory tests with white shrimp, feed consumption was 36.5 percent higher at 33 degrees-C than at 29. Growth was similar at both temperatures.
Compensatory gain is defined as faster than normal growth following a period of slower than normal growth, caused by nutritional and environmental factors.
Shrimp farm performance can often be below realistic production standards. Use proven nutrition, feeds and feeding techniques to improve profitability.
