“…After developing for decades in Asian, scientists have made certain progress in the feeding of climbing perch. There were several reports about ontogenesis, reproductive ecology and cultivation of climbing perch (Pavlov, 2021 ; Sarkar et al., 2005 ). Breeding climbing perch by spawned eggs using hormonal induction and farming fry fish in brackish water in different salinity were performed successfully (Chotipuntu & Avakul, 2010 ).…”

This study aimed to investigate nutrition in climbing perch Anabas testudineus which is an important nutritious economic freshwater fish in Asia and compare with Carassius auratus (crucian carp). Three kinds of tissues, including muscle, livers, and eggs, were isolated, respectively. Physicochemical properties including moisture, ash, protein, amino acids, fat, vitamins, and calcium contents in those tissues were determined. The results showed climbing perch muscle and liver contained less moisture, but more protein, amino acids, and vitamins than crucian carp muscle and liver. While moisture, ash, protein, and total amino acids contents of climbing perch egg were lower than those of crucian carp egg. Climbing perch egg had more fat, vitamins, and calcium than crucian carp egg. The amino acid profile was also performed, and 16 amino acids were identified and quantified in muscle, liver, and egg. Among tissues, the highest and lowest concentration of total amino acid content was found in crucian carp eggs and livers, respectively. Glutamic acid (Glu) and histidine (His) were the most and least amino acids in climbing perch and crucian carp tissues, respectively. Sixteen amino acids in climbing perch egg were less than those in crucian carp egg while it is an opposite case in muscle and liver, which amino acids of climbing perch tissues were more than those of crucian carp muscle and liver. Vitamin A of climbing perch was more than crucian carp in all three tissues, but vitamin E content in climbing perch liver was lower than that of crucian carp liver. Calcium content of muscle had no difference between two species. The abovementioned comparison of physicochemical properties of different tissues from China climbing perch and crucian carp will provide a necessary supplementary of freshwater muscle nutrition research, also was helpful for application of climbing perch.

“…Many rice paddies are located within the urban areas in Vietnam that resulted in their plastic contamination. Adult climbing perch are omnivorous and partially consume food from the water surface (Shingh and Samuel, 1981;Pavlov et al 2021). Expanded polystyrene due to positive buoyancy have high chances to be ingested.…”

The climbing perch Anabas testudineus is widespread in the inland waters of Vietnam and according to its ecology could have contact with a floating plastic waste. The fragments of expanded polystyrene (EPS) detected into the fresh waters of Vietnam in Khanh Hoa, Lam Dong, Phu Yen provinces. Our study was focused on estimation of probability of ingestion of EPS pellets (size 2.5–3.5 mm) by adult climbing perch. In the experiments three types of treatment pellets were proposed to fish: 24 feed pellets (Fp), 24 expanded polystyrene pellets (Pp), 12 feed & 12 expanded polystyrene pellets (FPp). Fish grasping time of first pellet was independent in all treatment types. The time grasping of 12th pellet was insignificant in Fp (63 s) and Pp (75 s). Climbing perch was grasping and ingesting of 24th Fp significantly (p = 0.02) earlier (143 s), than grasping of 24th Pp (817 s). Fish with FPp treatment was grasping feed along with EPS pellets, but grasping of 12th Fp was significantly (p = 0.02) earlier (49 s), then 12th Pp (193 s). By the end of tests fish ingested all feed pellets. We discovered that climbing perch grasped Pp and kept them in oral cavity, but always rejected them in 100% cases. This result evidenced that climbing perch has effective defense mechanism avoiding ingestion of expanded polystyrene pellets with size 2.5–3.5 mm, which realized by taste system and tactile reception of fish.
