This study analysed the influence of temperature, salinity and sediment texture on the distribution of pink shrimp juveniles (Farfantepenaeus brasiliensis) over a 20-year period. The shrimps were sampled monthly in Fortaleza Bay, north coast of São Paulo, Brazil, in November 1988–October 1989 (period 1) and then 20 years later in November 2008–October 2009 (period 2). In period 1 we captured 80 juveniles whereas in period 2 we captured 226. The abundance and distribution of F. brasiliensis seemed to be modulated by temperature and sediment texture, along with the fishing activity. The management strategies established between the samplings might have been responsible for the higher abundance of juveniles seen during period 2. The strategies included the limitation of fishing effort, regulation of fishing equipment and the establishment of environmental protection areas and temporary fishing ban.

这项研究分析了温度，盐度和沉积物质地对粉红色虾少年（Farfantepenaeus brasiliensis）在20年内的分布的影响。1988年11月至1989年10月（期间1）在巴西圣保罗北部海岸的福塔莱萨湾（Fortaleza Bay）每月取样一次，然后20年后于2008年11月至2009年10月（期间2）对虾进行采样。在第1阶段，我们捕获了80个少年，而在第2阶段，我们捕获了226个。F. brasiliensis的丰富度和分布似乎受温度和沉积物质地以及捕鱼活动的影响。两次采样之间建立的管理策略可能是造成第二阶段期间幼鱼数量增加的原因。该策略包括限制捕捞努力，管制捕捞设备，建立环境保护区和临时禁止捕捞。
