养殖三疣梭子蟹可实现反季节供应，实现高附加值，使梭子蟹产业快速发展。养殖业。然而，人们对梭子蟹室内育苗知之甚少，这就造成了种子供应与农民需求之间的差距。优化背景颜色是最大限度地提高幼虫性能的关键。三疣虫本研究旨在探讨梭子蟹幼蟹的颜色偏好，以及鱼缸颜色对从蚤状幼体到大眼幼体的存活、发育及耗氧率的影响。评价的罐颜色为红色、黄色、黑色、蓝色、绿色和白色。用自指颜色偏好仪研究了24 h内幼虫的颜色偏好。在存活和发育实验中，将新孵化的蚤状幼体I以100个个体L-1的初始密度饲养在1.4 L塑料培养罐中，用卤虫无节幼体喂养，直到它们全部变态为幼蟹。结果表明，各虫态幼虫对白色背景的偏好率均大于60%（P<0.01），其次为红色、蓝色和黄色。幼虫不喜欢绿色和黑色背景。在存活和发育试验中，红、黄缸中的幼虫表现最好（43.89 ± 2.22%和42.30 ± 4.16%），而白色缸中的幼虫最终存活率最低（19.78 ± 3.28%）（P<0.01）。幼虫在红色（19.7 ± 1.1 d−1）和黄色（20.5 ± 1.2 d−1）池中的发育同步性较好，而在黑色（22.1 ± 1.8 d−1）、蓝色（22.6 ± 1.3 d−1）、绿色（24.1 ± 1.7 d−1）和白色（24.1 ± 1.7 d−1）池中的发育同步性较差。在白色缸中培养的幼虫倾向于在缸底游泳，体色苍白。各期幼虫的耗氧率以蓝色池最高（P< .05），红色和白色池最低（P< .05）。结果表明，红、黄是幼虫适宜的底色。而白色背景可能成为应激源，应避免。
The cultured swimming crabPortunus trituberculatuscould be supplied out of season and achieve high-added value, leading to rapid development ofP. trituberculatusculture industry. However, little knowledge is known in indoor seeding of swimming crab, creating a gap between seed supplies and farmer's demand. Optimizing background colour is essential for maximizing the larval performance ofP. trituberculatus. The purpose of this study is to evaluate the colour preference of swimming crab larvae, and the effect of tank colour on survival, development and oxygen consumption rate from zoea I to megalopa. Tank colours evaluated were red, yellow, black, blue, green and white. A self-referent colour preference device was used to study colour preference of the larvae in 24 h. In the survival and development experiment newly hatched zoea I larvae were stocked into 1.4 L plastic culture tanks at an initial density of 100 individual L−1, fed with Artemia nauplii till they all metamorphosized to juvenile crab. Data indicated that >60% larvae of every stage had a significant preference to white background (P< .01), followed by red, blue and yellow. The larvae disliked green and black background. Surprisingly, in the survival and development experiment, the best larval performance was found in red and yellow tank (43.89 ± 2.22% and 42.30 ± 4.16%), while the larvae in white tank had the lowest final survival rate (19.78 ± 3.28%) (P< .01). The larvae also showed better synchronization in development in red (19.7 ± 1.1 d−1) and yellow (20.5 ± 1.2 d−1) tank than in black (22.1 ± 1.8 d−1), blue (22.6 ± 1.3 d−1), green (24.1 ± 1.7 d−1) and white tank (24.1 ± 1.7 d−1). The larvae cultured in white tank tended to swim on the bottom of the tank and had pale body colour. The larvae of all stages in blue tank had the highest oxygen consumption rate (P< .05), while those cultured in red and white had the lowest oxygen consumption rate (P< .05). The results indicated that the red and yellow are suitable background colour for larvalP. trituberculatus, while white background may become a stressor and should be avoided.
