This study investigated the relationships among parental body weight, egg size and number, and offspring performance at the larval, juvenile and grow-out stages of bighead catfish (Clarias macrocephalus) in Mekong domesticated (Can Tho; CT) and wild (Ca Mau; CM) strains. One-year-old broodstock from each strain were separated into two size groups, with those in the large (L) group having, on average, approximately double the body weight of those in the small (S) group.
