Catch volume refers to the total amount of fish or seafood that is captured during a specific period, often measured in weight or number of individual fish. This metric is crucial for assessing the health of fish populations and the sustainability of fishing practices. It helps fisheries managers make informed decisions about quotas and conservation efforts. Monitoring catch volume is essential for both commercial and recreational fishing. By tracking this data, authorities can ensure that fish stocks are not overexploited, which can lead to declines in species like cod or tuna. Sustainable practices help maintain ecological balance and support the fishing industry long-term.
