Pterobothrium Infestation 3. Parasitic infestations (protozoa, worms, etc.)

Cleaveius Infestation. Parasitic infestations (protozoa, worms, etc.)

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Found in estuaries and tidal rivers. Ascends rivers beyond tidal reach (Ref. 1479).

The Gagora catfish (Arius gagora) is a species of sea catfish in the family Ariidae. It was described by Francis Buchanan-Hamilton in 1822, originally under the genus Pimelodus. It is a migratory species found in the tropical marine, brackish and freshwater of Bangladesh, Myanmar, and India. It reaches a maximum standard length of 91.4 cm (36.0 in).

The Gagora catfish is of commercial importance as a food fish, but over-fishing has led to a population decline in the past two decades. Due to the decline, the IUCN redlist currently lists the species as Near Threatened.
