Breeding and cultivation of native Chironomid (Chironomus albidus) midges of the Guilan Province were carried out to produce larvae in rearing system and to be also used for feeding fish larvae and fingerlings. In this study, 4 metal trays (65×65×10 cm) and 6 plastic basins with the capacity of 35 L were designed and built. Trays and basins were installed vertically and then equipped with aeration and water supply systems. In small part of the rearing site, a 2-liter fiberglass tanks was used for collection of egg clutches. After collection and introduction of egg clutches into the trays and plastic basins, the amount of harvested Chironomid larvae were calculated during a consecutive rearing period. A total of 0.978 kg/m² larvae of Chironomid will be produced and harvested daily under rearing conditions. Results obtained from this study revealed that 382 g/m²chironomid larvae were harvested on the 15^th day of rearing as a percentage of the first reared group and then a total of 2 kg/m² larvae were obtained periodically from all the population of a group on the 16^th day of rearing.
