Essential fatty acid metabolism and requirements of the cleaner fish, ballan wrasse Labrus bergylta: Defining pathways of long-chain polyunsaturated fatty acid biosynthesis [PDF]

open access: yes, 2018
Ballan wrasse (Labrus bergylta) is an effective counter-measure against sea lice used by Atlantic salmon farmers, proving to be more effective and economical than drugs or chemical treatments alone.

Health assessment of the cleaner fish ballan wrasse Labrus bergylta from the British south-west coast [PDF]

open access: yesDiseases of Aquatic Organisms, 2019
Wild-caught ballan wrasse Labrus bergylta are translocated en masse from the British south-west coast to Scotland for use as cleaner fish to tackle Atlantic salmon Salmo salar sea lice infestations; however, very little is known about the background health status of this species.

Fish Predation in Bivalve Aquaculture: Impacts and Potential Mitigation Strategies

open access: yesReviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Fish predation poses a significant challenge to bivalve aquaculture throughout the global range of production. However, the issue remains poorly understood, preventing the advance of effective interventions. Fish predation, especially on mussels in longline culture, can be severe and, in some instances, lead to crop losses of up to 100%, which

Intraspecific variability in reproductive patterns in the temperate hermaphrodite fish, Labrus bergylta

open access: yesMarine and Freshwater Research, 2013
For many fish populations reproductive patterns remain unknown, which often results in inadequate management strategies. Timing and intraspecific variability in the main reproductive traits of ballan wrasse (Labrus bergylta) were investigated based on microscopic analysis of gonads sampled from NW Spain in 2009–2012. This species displays two main body

Policies to promote breeding for lice‐resistant salmon: Incentives designed for resilient and sustainable growth in aquaculture

open access: yesJournal of Fish Biology, Volume 106, Issue 1, Page 20-32, January 2025.
Abstract Sea lice represent a persistent and growing problem, challenging the resilience and growth of the salmon aquaculture industry. In this Norwegian case study, we studied and discuss how the absence of policy instruments directed at stimulating breeding for lice resistance (LR) might be explained.

Amoebic gill disease due to Paramoeba perurans in ballan wrasse (Labrus bergylta)

open access: yesAquaculture, 2013
AbstractBallan wrasse (Labrus bergylta) is cultured for the use as cleaner fish in Atlantic salmon farms. A low level of mortality was experienced in ballan wrasse broodstock tanks during spawning. Examined moribund and clinically healthy fish showed patchy gill lesions characteristic of amoebic gill disease (AGD).
