Yellowfin bream inhabit both coastal and estuarine waters of Eastern Australia between the Townsville area in northern Queensland and Lakes Entrance in Victoria. Yellowfin bream have a wide-ranging habitat that includes rocky headlands, beaches, estuaries and coastal rivers. Catches of yellowfin bream in NSW and QLD are considered healthy. Maximum weight of 4 kg and a length of 60 cm. Distribution The nets used to catch yellowfin bream generally have a low impact on habitat. Yellowfin Bream spawn around river mouths, and females produce planktonic eggs. Within estuaries, YFB are found in association with all types of habitat including sea grass beds, mangroves, sand flats, snags, bare substrates and rocky reefs. 6390).Other fish remain functional males throughout their life and another small proportion develop directly into females at the age of 4 years (Ref. Polluted water is a major threat to Yellowfin Bream and Tarwhine as this can cause a decline in their populations and the food they eat. Fishery impacts on threatened species appear minimal, although there has been no independent observer coverage in recent years. ... all types of habitat, including seagrass beds, mangroves, bare substrates and rocky reefs. It is highly fecund with females able to produce around half a million eggs annually. Environmental effects on Yellowfin Bream . Most sport fishers target bream in estuaries, where they congregate around structure. Similar Species. Often difficult to distinguish from the Black Bream, Acanthopagrus butcheri. Increased turbidity prevents the seagrass from being able to grow and therefore reducing the available habitat for Yellowfin Bream and Tarwhine. Size. The species is the basis of very significant recreational and commercial fisheries in NSW. They are opportunistic feeders with their diet including small crabs, prawns, molluscs, pipis and small fish. The Yellowfin Bream is a highly adaptable species in terms of its food and habitat requirements. A proportion of the population change sex from male to female after their first spawning season (Ref. (10.7% of variation), threadfin bream (9.7% of variation), yellowfin bream (9.3% of variation), eastern striped grunter Pelates sexlineatus (6.8% of variation), yellowfin tripodfish Tripodichthys angustrifrons (6.8% of variation) and silver biddy Gerres subfasciatus (5.9% of variation) were higher in abundance on the reef than at control sites. Following spawning, part of the population changes sex from male to female. Yellowfin bream also occur within the lower freshwater reaches of coastal rivers and lakes. The yellowfin enjoys a wide-ranging habitat from offshore reefs to the inter-tidal washes of islands, headlands and beaches. Habitat. Black bream are mostly confined to estuaries and rivers. They eat a wide variety of foods, including small Yellowfin Bream have a silver to olive-green body with yellowish pectoral, ventral and anal fins. Abundance of the larval stages is extremely high following the breeding season. 28504. The yellowfin bream has a long history of stability of both the length composition and commercial catch rate data. Planktonic postlarvae of yellow fin bream Acanthopagrus australis were found at surf bar entrances to Moreton Bay, a large subtropical estuarine system on the east coast of Australia. Yellowfin Bream are dependent on estuarine and inshore coastal habitats throughout their life cycle 25,26. Physical impacts on coastal marine vegetation, subsurface topography and water quality are likely to influence the resilience and productivity of Yellowfin Bream populations at local scales. 27246, 28262).Also Ref.
