Spencer Gulf fisheries, Marine Scalefish Fishery Catch and Effort Logbook Data (includes Miscellaneous Fisheries)

The Marine Scale Fishery has traditionally been one in which fishing effort shifts temporarily and spatially between species, depending on their relative abundance and value. SARDI research projects have concentrated on providing information on key biological parameters of several of the major species, including King George whiting, Snapper, Garfish, and Southern calamary.

The Marine Scale system monitors catch and effort fluctuations in South Australia's Marine Scalefish fishery and provides a basis for assessment of fish stocks. Quantity of fish (by species) and effort (by gear) expended in taking the catch is recorded by monthly returns submitted by the commercial fisher.

传统上，海洋规模化渔业（Marine Scale Fishery）的捕捞努力量（fishing effort）会依据不同物种的相对丰度与经济价值，在物种间进行临时且空间分布上的转移。SARDI的研究项目长期聚焦于为若干主要渔业物种的关键生物学参数提供基础数据支撑，涵盖乔治王沙鮻（King George whiting）、真鲷（Snapper）、颌针鱼（Garfish）以及南方枪乌贼（Southern calamary）等物种。

海洋规模化渔业监测系统（Marine Scale system）可对南澳大利亚州海洋规模化渔业的捕捞量与捕捞努力量波动进行监测，并为鱼类种群（fish stocks）评估提供依据。商业渔民需通过提交月度申报单，记录各物种的渔获量以及按渔具类型统计的捕捞努力量。
