CONTRIBUTING TO HIGH FISH WELFARE STANDARDS

Land-based Atlantic salmon farm

CHALLENGE

Contributing to high fish welfare standards

Land based farming requires high fish welfare standards, to maximize both productivity and product quality.

This implies all aspects related to production including fish handling at every production stage, from the hatchery, to grow-out and to processing. The challenge is to provide the highest fish welfare standards to a, by definition, high stressful process for the fish. This is only possible by taking care of every small detail.

SOLUTION: Aquaculture
COUNTRY: Japan
CUSTOMER: Proximar

Proximar is a land based farming of atlantic salmon at the foot of mount fuji, combining norwegian aquaculture expertise with modern and proven technology. euskan provides a complete fish handling system to meet highest fish welfare standard required by the project; materialized in two handling systems; one for smolt and post-smolt and second system for grow-out.

SOLUTION

The fish handling includes two differentiated systems targeting two different size ranges

Land based farming requires high fish welfare standards, to maximize both productivity and product quality.

The fish handling includes two differentiated systems targeting two different size ranges; smolt/post-smolt and grow-out. Both systems are placed strategically to enable fish transfer among different tanks by pipe hose quick coupling and are integrated by two tanks and two power unit: In terms of fish welfare, both systems integrate constant flow at suction side for reducing the need of crowding and positioning the fish at the center of the pipe which enables smother transition along pipe matrix and avoids physical contact with pipe wall and fittings.

Graders and counters enable proper sorting and in the case of the grow-out station, a high-capacity grader is configured allowing the harvesting process at grow-out size. Simple and customized interface allows total control of the fish transfer operation.
