Juvenile cleaner fish can socially learn the consequences of cheating [PDF]
Nature Communications, 2020 Cleaner fish can cheat clients for higher rewards but this comes with a risk of punishment. Here, Truskanov et al. show that juvenile cleaner fish can learn by observing adults to behave more cooperatively themselves but also to prefer clients that are ...

Rapid self-recognition ability in the cleaner fish [PDF]
Scientific ReportsWhether animals are self-aware has important implications for our approaches to both animal cognition and animal welfare. A landmark moment in animal cognition research was when great apes passed the mark-test and demonstrated mirror self-recognition ...

Brain morphology predicts social intelligence in wild cleaner fish [PDF]
Nature Communications, 2020 The causes and consequences of social intelligence are challenging to establish. A study on wild cleaner fish reports that large forebrains enable individuals to score higher in a social competence test, suggesting forebrain size is important for complex

The potential for cleaner fish‐driven evolution in the salmon louse Lepeophtheirus salmonis: Genetic or environmental control of pigmentation? [PDF]
Ecology and Evolution, 2021 The parasitic salmon louse represents one of the biggest challenges to environmentally sustainable salmonid aquaculture across the globe. This species also displays a high evolutionary potential, as demonstrated by its rapid development of resistance to ...

Do cleaning organisms reduce the stress response of client reef fish? [PDF]
Frontiers in Zoology, 2007 Background Marine cleaning interactions in which cleaner fish or shrimps remove parasites from visiting 'client' reef fish are a textbook example of mutualism. However, there is yet no conclusive evidence that cleaning organisms significantly improve the

From learning to reversal learning: How non-cleaner fish tackle the biological market task [PDF]
Animal CognitionThe biological market task – also known as the ephemeral reward task – models the mutualistic cleaning interactions between bluestreak cleaner wrasses and their client fish on coral reefs.

Cleaner fish escape salmon farms and hybridize with local wrasse populations [PDF]
Royal Society Open Science, 2018 The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered.

Cleaner fish with mirror self-recognition capacity precisely realize their body size based on their mental image [PDF]
Scientific ReportsAnimals exhibiting mirror self-recognition (MSR) are considered self-aware; however, studies on their level of self-awareness remain inconclusive.

Cleaner shrimp remove parasite eggs on fish cages [PDF]
Aquaculture Environment Interactions, 2018 Benthic stages of cultured fishes’ ectoparasites are a major contributor to persistent reinfections in aquaculture. These stages are resistant to chemical therapies and are costly to manage in terms of time and labour.
