Fishing 4.0 - Smart Buoy On the Fishing Pond
We are happy to announce the introduction of our brand new development, the Sensors2Net Smart Buoy, which helps fishermen prepare for best catch and provides fishing pond operators adequate and realtime information on water quality. The sensors, attached to Sensors2Net Smart Buoy, measure water parameters continuously and transfer them wirelessly to the internet, from where users can download ...

Artificial Intelligence in Aquaculture
The seventh and final installment in the series “Happy Fish – How Aquaculture Operators are Growing Better Fish.” While we will only be able to scratch the surface of this topic, there is great potential in machine learning and artificial intelligence applied with aquaculture and fish farm systems. We wanted to ask leading industry experts Matt Clarke of Poseidon Ocean Systems, ...

Anti‐anxiety drugs and fish behaviour: Establishing the link between internal concentrations of oxazepam and behavioural effects
Psychoactive drugs are frequently detected in the aquatic environment. The evolutionary conservation of the molecular targets of these drugs in fish suggest that they may elicit mode‐of‐action mediated effects in fish as they do in humans, and one the key open question is at what exposure concentrations these effects might occur. In the present study, we investigated the uptake and tissue ...

The effect of sub‐lethal concentrations of water soluble fraction of crude oil on the chemosensory function of caspian roach, Rutilus caspicus (Yakovlev, 1870)
The water‐soluble fraction (WSF) of crude oil is a complex and toxic mixture of hydrocarbons. Since aquatic organisms directly encounter it, WSF plays an important role in the toxicity of crude oil in aquatic environments. To determine whether fish are attracted to or avoid WSF, Caspian roach (Rutilus caspicus) were exposed to different concentrations of WSF in a choice maze apparatus. The ...

Efficiency and sustainability implications of artisanal fisheries activities: evidence from a developing country
Fisheries activities have an integral role to play in the livelihoods and economies of the Pacific island countries. However, the 'race to fish' behaviour assisted by the nature of property rights could lead to unsustainable resource extraction practices. In this paper, primary data on Fiji's artisanal fishermen and their fishing operation is used to examine their technical efficiency. Results ...
