Research could help improve the welfare of farmed lumpfish, a species used to control sea lice in salmon

Date
10 June 2020
Abstract

Healthy and/or moribund farmed and wild ballan wrasse Labrus bergylta (>0.5 to 900 g) were sampled from hatcheries (n = 2) and Atlantic salmon Salmo salar cage sites (n = 8) in Scotland between February 2016 and October 2018. Less than half of the sampled individuals (n = 43; 32.3%) had been...

Abstract

In this mini review, we systematized current knowledge about the number of Caligus elongatus on farmed Atlantic salmon in relation to the use of lumpfish as cleaner fish. The review was prompted by reports of an unusually large number of sea lice (C. elongatus) infestation of farmed salmon in...

Abstract

Coral aquaculture is expanding to supply the marine ornamental trade and active coral reef restoration. A common pest of Acropora corals is the Acropora-eating flatworm Prosthiostomum acroporae, which can cause colonial mortality at high infestation densities on Acropora spp. We investigated the...

Abstract

Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million cleaner fish per year. While small-scale experiments demonstrate the efficacy ...

Abstract

There is increased commercial interest in the production of lumpfish (Cyclopterus lumpus) as a biological control against sea lice infections in Atlantic salmon farming. To ensure a sustainable supply of lumpfish, reliable captive reproduction is required however, optimal husbandry and conditions...

Abstract

The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the economic importance, few genetic resources for downstream applications, such as...

Abstract

Interest and use of the lumpfish Cyclopterus lumpus L., 1758, as a cleaner fish in salmon aquaculture has grown significantly over the past 10 years. This has resulted in an explosion of new hatcheries to supply juveniles to the salmon industry. Until recently, these hatcheries have utilized a...

Abstract

Lumpfish (Cyclopterus lumpus) are widely applied as biological delousers in open net-pen farming of Atlantic salmon. As a species new to farming it is necessary to obtain a comprehensive understanding of the capacity of lumpfish to utilize plant derived feed ingredients. A feeding trial lasting for ...

Abstract

To investigate possible differences survival and welfare of lumpfish fed either feed blocks or commercially available pelleted feed in commercial cages, eight 90 m polar circle cages containing approximately 50,000 Atlantic salmon with a mean weight of 2 kg were stocked with 3800 lumpfish with a...
