Aquaculture, which is an important part of food supply, is usually carried out in cage nets made of textile materials. Fouling organisms settle on the cage nets over time, close the mesh openings, and cause unwanted weight gain. In order to prevent fouling, aquaculture nets are generally treated with antifouling paints. In this paper, warp knitted cage nets made from various raw materials were treated with three different antifouling paints. Econea was used as a biocide to prepare an eco‐friendly antifouling paint formulation, and two copper‐based commercial antifouling paints were supplied for comparison. Antifouling paint‐treated and untreated net samples were immersed in a marine ecosystem next to an aquaculture zone for 6 months. Settlement of fouling organisms on nets was observed by taking underwater photographs at periodic intervals. Following the field study, changes in the structure of the nets and antifouling performance of the paints were evaluated considering the results of underwater photographs, biomass growth, variation in mass and strength tests. Colour fastness of the antifouling paints to sea water was also measured to learn about biocide release and surface hydrophobicity. The results show that copper‐free eco‐friendly antifouling paint is just as effective against the fouling mechanism for all types of nets as copper‐based commercial antifouling paints. The novel eco‐friendly formulation has promising results, which provides an alternative for producers when considering the selection of raw materials.

环保型防污涂料配方可防止水产养殖网出现生物污垢

水产养殖是粮食供应的重要组成部分，通常在纺织材料制成的网箱中进行。随着时间的推移，污垢生物会沉积在网箱上，关闭网孔，并导致不必要的体重增加。为了防止结垢，通常用防污漆处理水产养殖网。在本文中，用三种不同的防污涂料处理了由各种原料制成的经编笼网。使用Econea作为杀菌剂来制备生态友好的防污涂料配方，并提供了两种铜基商业防污涂料进行比较。将经过防污涂料处理和未经处理的净样品浸入靠近水产养殖区的海洋生态系统中六个月。通过定期拍摄水下照片，观察到污垢生物在网上的沉降。经过现场研究，考虑到水下照片，生物量的增长，质量和强度测试的变化，评估了网状结构的变化和涂料的防污性能。还测量了防污漆对海水的色牢度，以了解杀生物剂的释放和表面疏水性。结果表明，无铜环保防污漆与铜基商用防污漆一样有效地对抗所有类型的蚊帐的结垢机理。新颖的环保配方具有令人鼓舞的结果，为生产者在选择原料时提供了替代选择。生物量的增长，质量和强度测试的变化。还测量了防污漆对海水的色牢度，以了解杀生物剂的释放和表面疏水性。结果表明，无铜环保防污漆与铜基商用防污漆一样有效地对抗所有类型的蚊帐的结垢机理。新颖的环保配方具有令人鼓舞的结果，为生产者在选择原料时提供了替代选择。生物量的增长，质量和强度测试的变化。还测量了防污漆对海水的色牢度，以了解杀生物剂的释放和表面疏水性。结果表明，无铜环保防污漆与铜基商用防污漆一样有效地对抗所有类型的蚊帐的结垢机理。新颖的环保配方具有令人鼓舞的结果，为生产者在选择原料时提供了替代选择。结果表明，无铜环保防污漆与铜基商用防污漆一样有效地抵御各种类型的蚊帐的结垢机理。新颖的环保配方具有令人鼓舞的结果，为生产者在选择原料时提供了替代选择。结果表明，无铜环保防污漆与铜基商用防污漆一样有效地对抗所有类型的蚊帐的结垢机理。新颖的环保配方具有令人鼓舞的结果，为生产者在选择原料时提供了替代选择。
