Penaid Prawn Larval Density - Species Level Counts (Two Genera Only), Gulf of Carpentaria 1975-1978

Gulf of Carpentaria prawn larval densities, recorded from stepped oblique bottom to surface plankton tows, using a 140-142 micron net. This dataset includes counts of Penaeid prawn larvae from the genus Penaeus and Metapenaeus only. Larvae of these genus were identified to species-level where possible, and are grouped by the seven stages of larval development (Protozoea 1-3, Mysis 1-3, Postlavae). Correction factors for depth and swept area are included, to allow calculation of estimates of prawn larval densities in standardised units (numbers per square metre, and numbers per cubic metre). These data are the result of nine cruises that took place between 1975 and 1978 on chartered boats and the "Kalinda". Prawn larval biomass and densities were measured in several transects across the Gulf of Carpentaria, as well as total plankton biomass.

本数据集为卡奔塔利亚湾（Gulf of Carpentaria）虾类幼体密度数据集，采用孔径140-142微米的浮游生物网，通过阶梯式斜向底至表层浮游生物拖网完成采样记录。数据集仅统计对虾科（Penaeidae）下滨对虾属（Penaeus）与新对虾属（Metapenaeus）的虾类幼体计数数据。该两属幼体在条件允许的情况下将鉴定至物种水平，并按幼体发育的7个阶段分组：蚤状幼体期1-3期（Protozoea 1-3）、糠虾幼体期1-3期（Mysis 1-3）以及仔虾期（Postlavae）。数据集包含水深与扫海面积校正因子，可用于以标准化单位（每平方米个体数、每立方米个体数）计算虾类幼体密度的估算值。本数据集源自1975年至1978年间开展的9次科考航次，采样船只包括租赁船舶与‘卡琳达号（Kalinda）’。研究人员在卡奔塔利亚湾内的多条断面中测定了虾类幼体生物量与密度，同时也同步测定了总浮游生物生物量。
