Data for: Waterbird abundance in aquaculture ponds: the significance of day and night and pond type

The loss of coastal wetlands represents a grave threat to waterbirds, prompting the use of artificial wetlands, such as aquaculture ponds, as a means of conservation. Aquaculture ponds are common in coastal areas and provide production value and ecological function as waterbird habitats. However, certain piscivorous birds may cause economic losses to the aquaculture industry. Different types of ponds provide habitat for various bird assemblages, and waterbirds exhibit nocturnal feeding behavior and utilize habitats distinct from those used during the day. Most waterbird surveys were conducted during the daytime, limiting our understanding of their nocturnal habitat utilization. This study conducted diurnal and nocturnal surveys on shorebirds, waterfowl, and Black-crowned Night Heron (Nycticorax nycticorax) ten times in three aquaculture ponds situated in the Cigu District of Tainan, namely fish/shrimp, hard clam, and abandoned ponds between October 2021 and November 2022. The results sh..., The aquaculture ponds in our study were classified into three types: fish/shrimp ponds, hard clam ponds, and abandoned ponds. Fish/shrimp ponds were utilized for cultivating milkfish, grouper, or white shrimp. These ponds, along with hard clam ponds, constituted the primary types of aquaculture in the study area, while abandoned ponds offered a semi-natural marsh environment. Field surveys were conducted ten times between October 2021 and November 2022, specifically in October, November, December 2021, January, February, March, May, July, September, and November 2022. Each survey round was carried out by a team of two experienced surveyors, who completed the surveys within two days. Surveyors recorded the bird species (or taxa), quantity, behavior (foraging/non-foraging), and water coverage (%) of each sampled pond. Water coverage was classified into four categories: low (0–30%), moderate (>30–60%), high (>60–90%), and full (>90%). To minimize disturbance to waterbirds, surveyo..., , # Data for: Waterbird abundance in aquaculture ponds: the significance of day and night and pond type

Our bird survey conducted diurnal and nocturnal surveys on shorebirds, waterfowl, and Black-crowned Night Heron ten times in three types of aquaculture ponds situated in the Cigu District of Tainan between October 2021 and November 2022.

The data contain year, month, aquaculture pond id, aquaculture pond area (ha), aquaculture pond type (fish/shrimp, hard clam, abandoned), time (day, night), water coverage (full, high, moderate, low), waterbird (shorebirds, waterfowl, night heron) and count.

海岸湿地的丧失对水鸟构成严重威胁，促使人们将水产养殖塘（aquaculture pond）等人工湿地作为水鸟保护的手段。水产养殖塘在沿海地区分布广泛，兼具生产价值与作为水鸟栖息地的生态功能。然而，部分食鱼鸟类会给水产养殖业造成经济损失。不同类型的养殖塘为不同鸟类群落提供栖息场所，且水鸟具有夜间觅食行为，其夜间利用的生境与日间存在差异。以往多数水鸟调查均在日间开展，这限制了我们对其夜间生境利用情况的认知。本研究于2021年10月至2022年11月间，在台南市七股区的三处水产养殖塘（分别为鱼虾塘、硬蛤养殖塘以及废弃养殖塘）内，对鸻鹬类（shorebirds）、水禽（waterfowl）以及夜鹭（Black-crowned Night Heron，学名*Nycticorax nycticorax*）开展了10次昼夜调查。本研究结果显示……（原文此处存在截断）。

本研究涉及的养殖塘分为三类：鱼虾塘、硬蛤养殖塘及废弃养殖塘。鱼虾塘用于养殖虱目鱼、石斑鱼或白虾，与硬蛤养殖塘均为研究区域内的主要水产养殖类型；废弃养殖塘则提供了半自然的沼泽生境。调查于2021年10月、11月、12月，2022年1月、2月、3月、5月、7月、9月及11月共计10个时段开展。每轮调查由2名经验丰富的调查人员组成的团队完成，且在2天内完成全部调查工作。调查人员记录了鸟类物种（或类群）、数量、行为（觅食/非觅食）以及每个采样养殖塘的水体覆盖率（%）。水体覆盖率分为四类：低覆盖（0%~30%）、中等覆盖（>30%~60%）、高覆盖（>60%~90%）以及全覆盖（>90%）。为尽量减少对水鸟的干扰，调查人员……（原文此处存在截断）。
