Village-level Nearshore Fish Landings for Kolono and Kolono Timur Districts of Southeast Sulawesi

This dataset contains (1) landings data for small-scale fishers (1GT or less boats or fish fence operators) in a nearshore fishery in Southeast Sulawesi, namely 9 villages in Kolono Bay, Kabupaten Konawe Selatan) and (2) a pdf map of the study area and fishing grounds grouped into geographical sectors. The dataset was generated during a Fulbright Student Research grant funded project. It was conducted as a demonstration project of how coral fisheries data can be collected on an ecosystem-scale (eg: all the villages hugging a bay, all the villages on an island). Sulawesi is a reef and nearshore fish biodiversity hotspot. Yet the state of local catch and fish stock information is considered data-poor. The provincial government gathers weekly data for 3GT+ boats that fish 1km+ offshore but it does not record catch of operators of the 1GT or less boats or beach-based fish fences, which contributes to regional fish consumption and market and restaurant sales.

Data collection for this dataset ran from November 2019 to March 2020, a time stretch matching the annual western monsoon. Each month, catch was recorded for 72 fishing trips across the 9 villages. Villages were grouped into 6 survey areas as four of the villages had few active fishers and so were grouped into a single survey area. Catch was sampled twice a month: once in the week around the full moon and once during one of the three other weeks a month that local fishers distinguish as “dark moon” periods with different fishery productivity. Each sample period, catch was recorded for 12 fishing trips in a survey area: 4 samples for each of the three main local area gear types – net, handline and fish fence. Fish landings were recorded using local names, identified to lowest possible taxon (species and occasionally genus) as shown in the Fish of Southeast Sulawesi guide that author Melati Kaye published with others. They compiled the book using a method that combined photograph identification and verification against FishBase database (www.fishbase.org). With consideration to fishers’ privacy, fisher names are cloaked in this dataset. Their fishing grounds are grouped into geographical sectors whose coordinates are stored in the shared data table and pdf map.

本数据集包含两部分内容：(1) 小规模渔民（船只吨位或鱼栅运营商不超过1GT）在东南苏拉威西近海渔业中的捕捞数据，具体为位于Kabupaten Konawe Selatan的Kolono湾的9个村庄的数据；(2) 研究区域和渔场的PDF地图，按照地理区域划分为若干部分。该数据集是在一项由富布赖特学生研究奖学金资助的项目中生成的，该项目旨在展示如何在生态系统尺度上收集珊瑚渔业数据（例如：环绕海湾的所有村庄，岛上的所有村庄）。苏拉威西岛是珊瑚和近海鱼类生物多样性的热点地区。然而，当地捕捞量和鱼群信息的状态被认为是数据匮乏的。省级政府每周收集3GT+船只的渔业数据，但并未记录1GT或以下船只或海滩鱼栅运营商的捕捞量，而这些捕捞量对区域鱼类消费、市场及餐饮销售产生了贡献。

数据收集时间从2019年11月至2020年3月，与年度的西南季风同期。每个月，对9个村庄中的72次捕捞行程进行了捕捞记录。由于四个村庄活跃的渔民数量较少，因此它们被合并为一个调查区域。每月对捕捞量进行两次抽样：一次在满月周围的周内，另一次在当月其余三周中的某一周，当地渔民将其称为“暗月”期，此时的渔业生产力有所不同。每个抽样周期，对调查区域内的12次捕捞行程进行记录：每个主要地方性捕鱼工具类型（网、手钓和鱼栅）各采集4个样本。捕鱼上岸记录采用当地名称，并尽可能地识别到最低分类单位（物种和偶尔的属），如Melati Kaye等人所著的《东南苏拉威西鱼类指南》中所示。该书通过结合照片识别和与FishBase数据库（www.fishbase.org）的比对验证方法编撰而成。考虑到渔民隐私，本数据集中对渔民姓名进行了匿名处理。他们的渔场被划分为地理区域，其坐标存储在共享数据表中，并在PDF地图中标注。
