An easy method is presented to breed tench (Tinca tinca L.) and to cultivate tench larvae for about 25 days in fish tanks in the hatchery. Post hatching development is recorded using scanning electron microscopy. Tench hatch in a rather embryonic stage without any external signs of mouth, gills, and pectoral fins. Some data on the growth during the first summer in ponds in monoculture and in biculture with carp (Cyprinus carpio L.) are proposed which show that tench of one batch do not grow exceptionally apart and that they have a remarkable growth rate when cultivated under appropriate conditions.

Key words: breeding, embryo, larva, fish tank, pond, growth rate
