Macro‐Hybrid and Micro‐Hybrid of Fish

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT This study reviews the progress in fish breeding, focusing on distant hybridization and gynogenesis, and introduces the theory of macro‐hybrid and micro‐hybrid. The macro‐hybrid refers to the allo‐progeny derived from distant hybridization, including the allo‐progenies.

Cytogenetic Analyses of Pseudopimelodus mangurus (Teleostei: Siluriformes: Pseudopimelodidae)

CYTOLOGIA, 2004
The cytogenetic analyses showed that Pseudopimelodus mangurus has a diploid number of 2n=54 chromosomes (6M, 26SM, 12ST and 10A), single Ag-NORs on the short arm of a middle-sized ST pair, identified as pair 19, and a very small amount of C-band positive segments in two chromosome pairs. The Ag-NORs are C-band positive.
