Assessing structure and seasonal variations of a temperate shallow water fish assemblage through Snorkel Visual Census

The shallow, brackish waters of the western Baltic Sea play a significant role in the life cycle of several commercial fishes, both as nursery and foraging areas. The fish assemblages of the inner 100 m is, however, surprisingly poorly studied, due to lack of effective methods for monitoring all fis...

Zusammenfassung:The shallow, brackish waters of the western Baltic Sea play a significant role in the life cycle of several commercial fishes, both as nursery and foraging areas. The fish assemblages of the inner 100 m is, however, surprisingly poorly studied, due to lack of effective methods for monitoring all fish species. In the present study, we applied Snorkel Visual Census (SVC) as a tool in monitoring shallow water (
