Acuity, the fineness with which sensory systems perceive and parse information, limits the
information that organisms can extract from stimuli. Here, we focus on visual acuity (the …

Stocking cleaner fish to control sea lice infestations in Atlantic salmon farms is widespread
and is viewed as a salmon welfare-friendly alternative to current delousing control …

It has become increasingly clear that a larger brain can confer cognitive benefits. Yet not all
of the numerous aspects of cognition seem to be affected by brain size. Recent evidence …

Tanks offer significant flexibility for aquaculture production. When in an optimally operated
water reuse configuration, they enable farming of most, if not all species of fish, in …

Eye size affects many aspects of visual function, but eyes are costly to grow and maintain.
The allometry of eyes can provide insight into this trade-off, but this has mainly been …

Turbidity plays an important role in aquatic predator–prey interactions. Increases in turbidity
are expected to reduce prey capture rates, especially for visually oriented predators …

Many fishes, both freshwater or marine, have colour vision that may outperform humans. As
a result, to understand the behavioural tasks that vision enables; including mate choice …

Frogs and toads (Amphibia: Anura) display diverse ecologies and behaviours, which are
often correlated with visual capacity in other vertebrates. Additionally, anurans exhibit a …

Human activities have resulted in higher levels of turbidity in aquatic systems due to
increased sediment runoff from agriculture, urbanization, and mining activities into nearby …

Visual acuity is one of three basic parameters that characterize a visual system. However,
few comparative studies of signals, camouflage and ecology in general have considered …
