Genome wide analysis reveals genetic divergence between Goldsinny wrasse populations

BMC Genetics, 2020
Background Marine fish populations are often characterized by high levels of gene flow and correspondingly low genetic divergence. This presents a challenge to define management units.

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, EarlyView.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Cleaner gobies can solve a biological market task when the correct cue is larger

Frontiers in Ecology and Evolution
Animal cognition is deeply influenced by interactions with the environment. A notable example of sophisticated cognition in the animal kingdom is described by the mutualistic relationship between cleaner fish and clients, where decision-making processes ...

Cleaner fish cause predators to reduce aggression toward bystanders at cleaning stations [PDF]

, 2017
Mutualisms, in which both participants gain a net benefit, are ubiquitous in all ecosystems, and the importance of understanding their broader ecological context has been demonstrated many times.

Growth and age differences between two male alternative reproductive tactics in the plainfin midshipman

Journal of Fish Biology, EarlyView.
Abstract The plainfin midshipman (Porichthys notatus Girard, 1854) is a toadfish with two distinct reproductive male tactics: ‘guarder males’ and ‘sneaker males’. These two tactics are anatomically, physiologically and behaviourally distinct from one another at sexual maturity, but it remained unclear whether these two male types remain fixed or ...

The glassy sweepers' way: seeking a versatile wrasse to be cleaned

Neotropical Ichthyology
Diurnal reef fishes compose the bulk of clients that seek cleaner fishes' services, but some nocturnal species that shelter at daytime also seek the cleaners.

Trematodes of the Great Barrier Reef, Australia: emerging patterns of diversity and richness in coral reef fishes [PDF]

, 2014
The Great Barrier Reef holds the richest array of marine life found anywhere in Australia, including a diverse and fascinating parasite fauna. Members of one group, the trematodes, occur as sexually mature adult worms in almost all Great Barrier Reef ...

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, EarlyView.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.
