Abstract
Triploidy was induced in channel catfish (Ictalurus punctatus) by cold‐shocking fertilized eggs at 5 C for 1.0 hour starting 5 minutes after fertilization. Chromosome counts from lymphocytes and kidney tissues showed 100% triploidy in the cold‐shocked group and 100% diploidy in the controls. Hatching success of eggs cold‐shocked 1.0 hour was 79% compared to 89% in the controls. Cold shocks longer than 1.0 hour caused 100% mortality.This publication has 3 references indexed in Scilit:
