As ecosystem engineers, crab behaviors not only reflect the physiological state and welfare of individuals but also act as regulators influencing the function and stability of aquaculture systems. However, research on the behavioral responses of cultured crabs to environmental factors remains incomplete, and studies on how their behaviors affect the environment are even more limited. To enhance productivity, welfare, and envir...

Crab fisheries play a crucial role in global fishery economics, but they heavily rely on wild catches. With the decline and exploratory limits of wild populations, expanding the scale and production of aquaculture becomes vital for the sustainability of crab fisheries. The development of crab aquaculture encounters significant dietary challenges, stemming from suboptimal formulated feeds and inefficient feeding management. Lev...

Vitamin D (VD) is a steroid hormone, of which vitamin D 3 (VD 3 ) is the main form in fish. Fish obtain VD 3 majorly from diets, and VD 3 has been widely used in aquatic feed as feed additive. As one of the essential nutrients, VD 3 plays an indispensable role in the growth and health of fish. Due to the particularity of the fish living environment, the metabolic and physiological functions of VD 3 in fish have some difference...
