Effects of starvation and refeeding on 35 S sulfate uptake by the branchial cartilage of the grass carp fingerling were examined in vitro Starvation reduced 35 S sulfate uptake by the branchial cartilage After being starved for 15 days

the level of 35 S sulfate uptake by the branchial cartilage was significantly lower than the fed controls Refeeding increased 35 S sulfate uptake by branchial cartilage of the starved grass carp fingerling similar to the levels of the constantly fed controls These results indicated that nutritional states affect the growth activity of branchial cartillage of the grass carp fingerling
