Mixed Strain

A mixed-strain catla is not a formal breed, but a farm or hatchery stock of Catla catla made from more than one source population or breeding line. Catla, also called catla carp or Indian major carp, is a large South Asian freshwater fish with a deep body, broad head, and surface-feeding habit. Mixed strains may be used to widen broodstock genetics, improve seed availability, or combine fish from government, private, and local hatcheries, though their performance is only as reliable as the selection behind them.

In aquaculture, mixed-strain catla are managed like other catla: warm ponds, good dissolved oxygen, plankton-based feeding supplemented with formulated or farm-made feeds, and polyculture with rohu and mrigal where appropriate. Hatcheries should track broodfish origin to avoid accidental inbreeding or repeated use of closely related parents. Farmers buying fingerlings need uniform size, active swimming, and disease-free stock more than a color label, and should quarantine or acclimate fish before stocking.
