Thompson Beach is a locality in the Australian state of South Australia located on the eastern coastline of Gulf St Vincent about 56 kilometres (35 miles) north of the Adelaide city centre. [3] [2] Thompson Beach started as a sub-division in 1980 with boundaries being created in June 1997. [2] [7] Land use with the locality is principally residential with built development being of a ‘low density’. [7] Thompson Beach is located within the federal Division of Grey, the state electoral district of Narungga, and the local government area of the Adelaide Plains Council. [4] [2]
Thompson Beach is particularly known for its blue swimmer crabs, with the prime season being from October to April. The beach has an extremely gradual incline, allowing a fisherman to walk several hundred meters out to sea during low tide while the water remains below knee level: this provides a vast area for crabbing. Special crab rakes are employed to capture these crabs around seagrass patches. [8] It is advised to handle the crabs gently to prevent damage and adhere to strict limits enforced by the PIRSA: a personal daily bag limit of 20 (combined with sand crabs), a daily boat limit of 60 (for groups of 3 or more), and a minimum legal size of 11 cm. Females with external eggs must be released immediately. [9]
In recent years, a greater emphasis has been put on sustainable practices to preserve this ecosystem, encouraging a relaxed approach that minimizes harm to the crabs and their habitat. [10]
