Oyster cultivation is the oldest and largest aquaculture industry in south-eastern Australia. Oyster spat are grown to marketable size in rack-and-rail (‘racks’) or longline-and-basket (‘baskets’) configurations, which add structure to estuarine waters. This study assessed: (1) how the fish communities associated with oyster farms vary with production method; (2) how communities of fish utilise oyster infrastructure, as compared to adjacent natural habitats; and (3) whether oyster infrastructure can serve as de facto oyster reefs by supporting similar fish communities. Remote underwater video surveys, conducted during summer and winter of 2 study years, revealed that fish observations and species richness were generally greater for rack than basket cultivation. Both types of oyster farms supported at least as many species of fish as adjacent natural habitats, including oyster reef, seagrass, mangrove and bare sediment. Fish communities were, in general, most similar between racks and baskets and most dissimilar between racks and bare sediments. Oyster farms supported species of fish otherwise limited to habitats with wild oysters, and unique harvested fish species were ob served more frequently at racks. Fish use of oyster-growing infrastructure for foraging and shelter mirrored use of natural biogenic habitats. Overall, this study suggests that the oyster aquaculture infrastructure can support fish communities with species composition similar to those of natural biogenic habitats, although this service is dependent on farming method. Ecosystem services provided by aqua-culture should be considered in estuarine habitat enhancement, conservation and restoration","PeriodicalId":8376,"journal":{"name":"Aquaculture Environment Interactions","volume":"1 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69594345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such aggregations may have various impacts on farmed and wild fish, the environment, fish farming, and fisheries activities. Therefore, it is important to understand the patterns and amount of wild fish aggregations at aquaculture sites. In recent years, the use of artificial intelligence (AI) for automated detection of fish has seen major advancements, and this technology can be applied to wild fish abundance monitoring. We present a monitoring procedure that uses a combination of multiple cameras and automatic fish detection by AI. Wild fish in images collected around commercial salmon cages in Norway were automatically identified and counted by a system based on the real-time object detector framework YOLOv4, and the results were compared with manual human counts. Overall, the automatic system resulted in higher fish numbers than the manual counts. The performance of the system was satisfactory regarding false negatives (i.e. non-detected fish), while the false positive (i.e. objects wrongly detected as fish) rate was above 7%, which was considered an acceptable limit of error in comparison with the manual counts. The main causes of false positives were confusing backgrounds and mismatches between detection thresholds for automated and manual counts. However, these issues can be overcome by using training images that represent real scenarios (i.e. various backgrounds and fish densities) and setting proper detection thresholds. We present here a procedure with great potential for autonomous monitoring of wild fish abundance at aquaculture sites.","PeriodicalId":8376,"journal":{"name":"Aquaculture Environment Interactions","volume":"1 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69594357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
