The invention discloses a
system and a method for detecting
attack behaviors and
ingestion behaviors of crabs, and belongs to the technical field of
animal behavior detection. A plurality of experimental crabs are placed in an experimental box, a semi-
natural environment is provided, and under the
group level, on the basis that
carapace of the experimental crabs is coated with marks with different colors, the
carapace of the experimental crabs is marked with marks with different colors; crab behavior videos are shot in real time through a high-definition camera shooting
observation system arranged above the experiment box, and the activity or movement of each crab in a group is recognized and tracked in real time by using a computer
animal behavior tracking and analysis unit and adopting a dynamic subtraction method and a color marking auxiliary technology. The behavior
phenotype data, the movement track and the
heat map of each crab are automatically identified and analyzed, and the behavior change of the experimental crab group is tracked, analyzed and observed in a semi-
natural environment. According to the method, researchers can be helped to quantify
attack behaviors and
ingestion behaviors of crabs in a group better, so that the experimental result is good in stability, high in
repeatability, low in labor cost and convenient and rapid to operate.
