Lake Garda Stocking: Seven Million Coregone Lavarello Fry Released

The Province recently carried out a stocking activity in Lake Garda, releasing approximately seven million fry of coregone lavarello, obtained through artificial fertilization and incubation of eggs at the Peschiera fish hatchery. This productive activity was conducted in collaboration with the Province of Brescia, which supplied the larvae produced by itself into its designated section of the lake.

Production and Release Procedure

The first phase of this production process involves capturing coregone breeders by professional fishermen authorized by the Province for this purpose: followed by their in situ spawning, then fertilization, and subsequent incubation of the eggs at the Peschiera hatchery in specialized bottles in which water circulates continuously.

The hatchling emergence occurs after approximately a month, depending on the water temperature. A few days later, the larvae are released into the lake, ideally in the areas where spawning took place.

Fishery Management and Targeted Species

The fishery management of Lake Garda includes, besides the annual stocking with fish material purchased from outdoor hatcheries, primarily the release of fry produced in local hatcheries from breeders captured locally by professional fishermen.

This activity has been successfully practiced for years, with particular focus on valuable species such as lavarello, lucioperca (zander), and in the past also carpione (European chub) and occasionally perch.
