“…2). Earlier, we showed that the movement of climbing perch in the aquatic environment usually occurs in a group (Pavlov et al, 2020). Consequently, this species could maintain group behavior both in the water and on land.…”

“…An expansion in the number of moves of climbing perch to the surface of the water for swallowing atmospheric air with a decrease in the water level has indicated an increase in respiration intensity: air exchange in the supragillary region of the labyrinth organ (Kasumyan et al, 2021). The frequency of climbing perch jumps could indicate increased migration activity (the initial type of terrestrial migration) (Pavlov et al, 2019(Pavlov et al, , 2020. With a sufficient (>2 cm) water level, jumping towards the ladder helps climb to land into the passageway of the "dry maze".…”

Abstract— The study presents the behavior and movement characteristics of climbing perch Anabas testudineus in the “dry maze” installation. Two types of behavior were identified in climbing perch when the water level in the starting tank decreases to the critical value: waiting (often in a compact group at the bottom of the starting tank) or exit to ashore (land) and moving (migration). Movements usually take place in a group of two to four individuals. The fish chose a tank with the water randomly and remained there until the end of the experiment. If individuals become to an empty tank, they, as a rule, leave it and continue to search for water. Thus, the search for a new waterbody is determining the terrestrial migration of climbing perch.
