Aligning Fishing Gear Selectivity With Harvest Slot Limits for Ballan Wrasse Labrus bergylta

Aquaculture, Fish and Fisheries
Selectivity is an important parameter used to identify the portion of a stock caught by a fishing gear. In principle, fisheries management aligns the length at which 50% of individuals are selected for (L50) with minimum landing sizes.

Genomic Landscape of Divergence in Ballan Wrasse (Labrus bergylta). [PDF]

Mol Ecol
ABSTRACT The architecture underpinning genomic divergence is still a largely uncharted territory and likely case‐dependent. Here, we investigated genome‐wide variation in Ballan wrasse, a northeastern Atlantic fish species that displays two sympatric colour morphs, spotty and plain, that have been suggested to represent subspecies. We

Intestinal Function of the Stomachless Fish, Ballan Wrasse (Labrus bergylta) [PDF]

Frontiers in Marine Science, 2019
Little is known about the digestion of nutrients in stomachless (agastric) fishes with short intestines, such as wrasse. This study describes the digestion, absorption and evacuation rates in ballan wrasse (Labrus bergylta) fed either dry or pre-soaked ...

Allometric growth and development of organs in ballan wrasse (Labrus bergylta Ascanius, 1767) larvae in relation to different live prey diets and growth rates [PDF]

Biology Open, 2016
Small fish larvae grow allometrically, but little is known about how this growth pattern may be affected by different growth rates and early diet quality. The present study investigates how different growth rates, caused by start-feeding with copepods or

Loss of stomach, loss of appetite? Sequencing of the ballan wrasse (Labrus bergylta) genome and intestinal transcriptomic profiling illuminate the evolution of loss of stomach function in fish [PDF]

BMC Genomics, 2018
Background The ballan wrasse (Labrus bergylta) belongs to a large teleost family containing more than 600 species showing several unique evolutionary traits such as lack of stomach and hermaphroditism.

Insights into the early gonad development of the protogynous ballan wrasse (Labrus bergylta)

Aquaculture Reports, 2023
The reproductive biology of ballan wrasse, a popular cleaner fish species now bred in captivity, is not well understood particularly the early stages of development and their accompanying endocrine changes. The protogynous nature of this species has been

Phylogeography of Labrus bergylta (Pisces: Labridae) in the north-eastern Atlantic

Frontiers in Marine Science, 2015
The ballan wrasse, Labrus bergylta (Labridae), is a protogynous hermaphrodite fish common in the north-eastern Atlantic from Norway to Morocco. It is a commercially important resource for local fisheries and is currently being used as cleaner fish to ...

Does sedation with AQUI-S® mitigate transport stress and post transport mortality in ballan wrasse (Labrus bergyltae)? [PDF]

Frontiers in Veterinary Science
Ballan wrasse (Labrus bergylta) are commonly used as cleaner fish in salmon farms as a biological treatment to mitigate sea lice infestation. Improved welfare for cleaner fish both during production of these fish and when in sea-cages with salmon is ...

Assessing the impact of spear fishing by using competitions records and underwater visual censuses [PDF]

Scientia Marina, 2016
Recreational fishers are increasingly competing for space and resources with commercial fishers worldwide, but have been poorly studied. In particular, the impacts of spearfishing competitions on the temperate fish assemblages have seldom been analysed ...
