稻虫复合种养模式疣吻沙蚕的主要气象因子影响分析

Analysis of the Main Meteorological Factors Affecting Tylorrhynchus heterochaetus in the Rice-Field Insect Integrated Breeding and Cultivation Model

摘要: 本研究聚焦于稻虫生态复合种养模式下疣吻沙蚕的气象因子影响分析。疣吻沙蚕作为一种重要的海洋生物资源，具有显著的生态和经济价值，但其天然资源量因过度捕捞和生态环境变化而急剧减少。阳江市作为我国西南沿海重要的水产养殖基地，其稻虫生态复合种养模式发展迅速，但受台风、高温等灾害性天气影响较大。研究基于阳江市的气象数据，分析温度和湿度对疣吻沙蚕生长的影响。结果表明，阳江市7月和8月高温日数较多，11月至次年3月的相对湿度较低，适宜疣吻沙蚕的生长和蜕皮。结合温度和湿度的空间分布特征，建议在阳东区东南部和江城区南部开展养殖，并以10月至次年3~4月为最佳养殖周期，以降低高温和湿度变化对产量的影响。本研究为阳江市疣吻沙蚕的生态养殖提供了科学依据，对提升养殖效益具有重要意义。

Abstract: This study focuses on the analysis of the impact of meteorological factors on the bioturbation polychaete (Perinereis aibuhitensis) in the rice-pest ecological integrated cultivation and breeding model. As an important marine biological resource, the bioturbation polychaete holds significant ecological and economic value. However, its natural resource stock has been sharply declining due to overfishing and changes in the ecological environment. Yangjiang City, an important aquaculture base along China’s southwestern coast, has seen rapid development of the rice-pest ecological integrated cultivation and breeding model. However, it is highly susceptible to disastrous weather conditions such as typhoons and high temperatures. Based on meteorological data from Yangjiang City, this study analyzes the effects of temperature and humidity on the growth of the bioturbation polychaete. The results show that the number of high-temperature days in July and August is relatively high, while the relative humidity from November to March of the following year is relatively low, which is suitable for the growth and molting of the bioturbation polychaete. Considering the spatial distribution characteristics of temperature and humidity, it is recommended to conduct aquaculture in the southeastern part of Yangdong District and the southern part of Jiangcheng District, with the period from October to March-April of the following year being the optimal breeding cycle to minimize the impact of high temperatures and humidity fluctuations on production. This study provides a scientific basis for the ecological breeding of the bioturbation polychaete in Yangjiang City and is of great significance for improving breeding efficiency.
