Abstract
In recent years, fishery has developed rapidly. For the vital interests of the majority of fishermen, this paper makes full use of Internet of Things and air–water amphibious UAV technology to provide an integrated system that can meet the requirements of fishery water quality monitoring and prediction evaluation. To monitor target water quality in real time, the water quality monitoring of the system is mainly completed by a six-rotor floating UAV that carries water quality sensors. The GPRS module is then used to realize remote data transmission. The prediction of water quality transmission data is mainly realized by the algorithm of time series comprehensive analysis. The evaluation rules are determined according to the water quality evaluation standards to evaluate the predicted water quality data. Finally, the feasibility of the system is proved through experiments. The results show that the system can effectively evaluate fishery water quality under different weather conditions. The prediction accuracy of the pH, dissolved oxygen content, and ammonia nitrogen content of fishery water quality can reach 99%, 98%, and 99% on sunny days, and reach 92%, 98%, and 91% on rainy days.

Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. According to the official website of the US Bureau of Labor Statistics and the China. Fishery Ship Safety Analysis Report (1994–2015) statistics, since 2012, the global fishery worker mortality rate has been hovering around 0.08%, which is nearly 59 times that of industrial, mining, and commercial enterprises. The complex soil environment around the waters is one of the main reasons for the tragedy. As the phenomenon of water pollution becomes increasingly serious, various countries give increasingly more attention to fishery safety, and the requirements for water quality are greater than ever. The demand for water quality monitoring devices is increasing.
