System for producing larvae for fishing and for feeding trout in hatcheries

摘要

The invention relates to the system of producing larvae from larvae: the fly is born, it lays the eggs from which the larvae are born which in turn produce a cocoon, giving rise to new flies and so on in succession, the fly being fed on sugar and water. The cocoons are placed in trays which will be placed in the rooms denoted No. 1 in the drawing (fly room). Seven days later, the flies are born and these will be fed on water and sugar (granulated sugar). The flies will begin to lay 10 to 14 days after birth. At this time, trays containing meat and fish are placed in rooms Nos 1, where the flies will lay eggs for 24 hours. The trays with the meat and the fish which already contain the eggs are then transferred to rooms No. 6 (trough rooms), being placed in cement troughs where the larvae, after birth, develop, continuing to be fed on meat (liver and heart) and fish, for 7 days. At the end of this period, the larvae are ready for sale. The invention consists in the production of larvae for fishing and for feeding trout in hatcheries. IMAGE
