Comments: Known Ambacan River at Makinhas and Butigan, Leyte in 1993 (Ref. 7223), Kalinawan River (Ref. 81829), Laguna de Bay (Ref. 80824), Lake Buluan (Ref. 13492), Lake Taal (Ref. 13446), Lake Naujan (Ref. 13446, 81829), Paoay Lake (Ref. 80830), Lake Lanao (Ref. 81887, 95183), and Lake Mainit, Mindanao (Ref. 4867). Also recorded from Paitan Lake, Pantabangan Dam, and Tabuating River (Nueva Ecija) (Ref. 109918). Completely dominated natural populations in lakes and rivers and the indigenous Clarias macrocephalus which can hardly be found in the markets today. Occurs in swamps, ponds, ditches, rice paddies, and pools left in low spots after rivers have flooded (Ref. 2854). Also Ref. 1739, 6096, 7050, 12550, 36654, 43638.

Asia: Java, Indonesia. Clarias aff. batrachus from Indochina and Clarias aff. batrachus from Sundaland have been misidentified as Clarias batrachus from Java. Introduced elsewhere. Several countries report adverse ecological impact after introduction.

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 60 - 76; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 47 - 58. Body compressed posteriorly. Upper jaw a little projecting. Spine of pectoral fins rough on its outer edge and serrated on its inner edge (Ref. 4792). Occipital process more or less triangular, its length about 2 time in its width (Ref. 27732); distance between dorsal and occipital process 4-5.5 times in distance from tip of snout to end of occipital process (Ref. 43281). Genital papilla in males is elongated and pointed (Ref. 52012).

Facultative air-breathing (Ref. 126274); Adults inhabit lowland streams (Ref. 57235), swamps, ponds, ditches, rice paddies, and pools left in low spots after rivers have been in flood (Ref. 2854, 57235). Usually confined to stagnant, muddy water (Ref. 1479). Found in medium to large-sized rivers, flooded fields and stagnant water bodies including sluggish flowing canals (Ref. 12975). Undertake lateral migrations from the Mekong mainstream, or other permanent water bodies, to flooded areas during the flood season and returns to the permanent water bodies at the onset of the dry season (Ref. 37770). Can live out of water for quite sometime and move short distances over land (Ref. 4833). Can walk and leave the water to migrate to other water bodies using its auxiliary breathing organs. The Lao use this fish as lap pa or ponne pa. Feed on insect larvae, earthworms, shells, shrimps, small fish, aquatic plants and debris (Ref. 6459). An important food fish (Ref. 4833) that is marketed live, fresh and frozen (Ref. 9987). Recently rare, being replaced by introduced African walking catfish (Ref. 57235).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

The pair manifests the 'spawning embrace' which is widely observed in other catfish species (Ref. 33313). The pair gently nudge each other in the genital region and flick their dorsal fins; male wraps his body around the female, then the female releases a stream of adhesive eggs into the nest (Ref. 44091). In southeast Asia, spawning period is during the rainy season, when rivers rise and fish are able to excavate nests in submerged mud banks and dikes of flooded rice fields (Ref. 40977).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00500 - 0.01662), b=2.93 (2.78 - 3.08), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.50 se; based on food items.

устойчивость к внешним воздействиям (Ref. 120179): высокий, минимальное время удвоения популяции до 15 месяцев (K=0.7 (in aquarium); tm=1; Fec=2,300-13,400).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
