Crayfish optimization algorithm

Artificial Intelligence Review, 2023
This paper proposes a meta heuristic optimization algorithm, called Crayfish Optimization Algorithm (COA), which simulates crayfish’s summer resort behavior, competition behavior and foraging behavior. The three behaviors are divided into three different stages to balance the exploration and exploitation of algorithm. The three stages are summer resort

Effects of different fertilization patterns on the dietary composition of Procambarus clarkii in a rice-crayfish coculture system

Aquaculture Reports, 2023
As an omnivorous species, crayfish (Procambarus clarkii) have varying feeding habits in different environments. However, little is known about the diet of crayfish under different fertilization patterns in rice-crayfish cocultures.
