Floating faeces for a cleaner fish production

Floating faeces for a cleaner fish production

Recent developments in European recirculating aquaculture systems suggest expanding potential for this extremely water-efficient technique. However, the technology still faces challenges due to concerns over economic efficiency and system stability—both essential in minimizing the risk of financially and environmentally expensive failures. One key factor in maintaining stable production conditi...

Cleaner fish

The authorities in Modena hope the bats can stop the onslaught of the tiger mosquito. Council workers place the bat boxes in quiet, dark, south-facing sites that bats prefer for breeding in the early months of the year. “We are trying to think of what we could do to exploit their natural predators and so we thought of bats,” says Modena’s environment councillor Simona Arletti. “Until now the me...

Cleaner Fish Drives Local Fish Diversity on Coral Reefs

Coral reefs are one of the most diverse habitats in the world, yet our understanding of the processes affecting their biodiversity is limited. At the local scale, cleaner fish are thought to have a disproportionate effect, in relation to their abundance and size, on the activity of many other fish species, but confirmation of this species' effect on local fish diversity has proved elusive. The ...

Are cleaner fish, Labroides dimidiatus, inequity averse?

Please cite this article in press as: Raihani, N dx.doi.org/10.1016/j.anbehav.2012.06.023 Inequity aversion (IA), a willingness to incur temporary costs to prevent unequal outcomes, is common in humans and thought to be beneficial in the context of cooperative relationships with nonkin, since it might allow individuals to regulate contributions to cooperative activities. Attempts to address whe...
