Remote video provides new insights into spawning aggregation dynamics of the black-saddled coral grouper

Spawning fish are attractive for fishermen. High catch rates can generally be expected during spawning times at specific locations. However, these sites are also very important for the conservation of the fish species that spawn there. With the help of remote underwater video cameras, an international team of scientists has analyzed the spawning aggregation dynamics of the black-saddled coral grouper (Plectropomus laevis) in the South Pacific.
