摘要

Every year, the Texas Parks & Wildlife Department spends millions of dollars breeding red drum, a popular game fish, releasing between 20 and 30 million hatchery-raised fingerlings into eight different bays and estuaries along the coast. In order to maximize the numbers that survive to adulthood, the practice has been to provide adult fish a diet rich in fatty acids for nine months before breeding season. During breeding season, to save money and resources, the diet is less rich. University of Texas researchers set out to find evidence that this is an effective practice.
