Tunabio: biological traits of tropical tuna and bycatch species caught by purse seine fisheries in the Western Indian and Eastern Central Atlantic Oceans

along with the development of the tropical tuna purse seine fishery from the 1960s in the atlantic ocean and from the 1980s in the indian ocean, many projects and studies have been conducted to improve knowledge about the biology, migrations, and dynamics of the stocks of target and non-target (i.e., bycatch) species taken in these fisheries. since the 2000s, the european union (eu) has been supporting member states in the collection of biological data on species caught by their purse seine and pole and line fisheries, thus making it possible to have long-time series of data. these data are essential to monitor the status of the fisheries and fuel the assessment models used by the tuna regional fisheries management organisations (trfmos) for the sustainable management and conservation of the fish stocks under their mandate.we combined historical (1974-1999) and current (2003-nowadays) data sets on the biology of tropical tunas and bycatch fish caught by large-scale purse seiners in the eastern atlantic ocean (eao) and western indian ocean (wio). the resulting tunabio database contains all available morphometric and biological data collected on more than 80,000 fish individuals.

随着大西洋洋面上自20世纪60年代和印度洋上自1980年代以来热带金枪鱼围网渔业的不断发展，诸多项目与研究得以开展，旨在提升对目标物种及非目标物种（即误捕）的生物学、迁徙规律及种群动态的了解。自2000年起，欧盟（EU）一直支持成员国收集其围网和钓线渔业捕获物种的生物数据，从而实现了长时间序列数据的积累。这些数据对于监测渔业状况及驱动金枪鱼区域渔业管理组织（TRFMOs）所使用的评估模型，以实现其管理权限下鱼群资源的可持续管理和保护至关重要。我们结合了历史（1974-1999）和当前（2003至今）数据集，这些数据集记录了在东大西洋洋（EAO）和西印度洋（WIO）大型围网渔船捕获的热带金枪鱼和误捕鱼类的生物学信息。由此构建的Tunabio数据库囊括了超过80,000条鱼类的所有可用形态学和生物学数据。
