H/T @ Sam McClatchie | Rewired ex-NOAA Fisheries Oceanographer. Creator of Fishing Maps. Now based in Huia, near Auckland, New Zealand.
“The vertical structure of the upper ocean has a big effect on the productivity and distribution of plankton near the surface of the ocean. The vertical structure also affects the concentration of feed, and that affects the behaviour of Bluefin. Vertical structure of the water is controlled by the interaction of heating by the sun, wind-driven mixing, and the density of the water. In offshore areas, or in areas away from river outflows, density is determined mainly by water temperature. The sun warms the surface of the ocean, and the wind blowing over the ocean distributes the heat by mixing the water.
As the sun warms the surface water it becomes less dense and forms a cap sitting on top of the cold deeper water. The temperature changes rapidly at the boundary between the warm less dense surface water and the denser, cooler water below. This boundary is called the thermocline. If you have ever swum in a lake in the summer and found it warm as bathwater in the surface, but freezing cold when you dropped your feet down, you have experienced the effect of a thermocline.
When there is a warm cap on the ocean, the water is said to be stratified (or layered). If the wind has been calm, and the weather sunny, the warm surface layer will be stable, and strongly stratified conditions may develop. In these conditions, Bluefin dive frequently to relatively shallow depths (less than 100 metres). They dive rapidly, feed below the thermocline and return to the surface waters frequently, spending as much as 65% of their time in the upper 10 metres…
Concentrations of feed often occur just below the thermocline. These layers can be seen on an echosounder. Bluefin dive down through the thermocline to feed on these layers. When the water is strongly stratified, the Bluefin dive more frequently to feed. They also dive faster, and stay less time in the deep cold water than they do when the water is well mixed.
Bluefin use this foraging strategy during both day and night. These fish maintain a body temperature warmer than the water, so they remain highly efficient swimmers in cold water..."

After circulating through #AI #DataCenter cooling systems, water may be discharged back into surface waters at higher temperatures. Warmer discharge water can:
*reduce dissolved oxygen levels
*stress fish and aquatic organisms
*promote algal blooms
*cause long-term changes to aquatic ecosystems

'When I first became involved in advocating for eastern #tarakihi in 2019, #Fisheries New Zealand’s own #science estimated the eastern stock had fallen to around 16% of its unfished #biomass—well below the 20% soft limit and nowhere near the #Harvest Strategy Standard target of 40%.
'Six years later, we’re paying substantially more at the checkout, yet the eastern stock remains well under a rebuilding-plan target.
'Recent projections suggest it is still hovering around the lower management thresholds, with recovery far from assured under current catch settings.
'That should concern every New Zealander.
We’ve somehow normalised the idea that a fish can become increasingly expensive while remaining chronically depleted. Consumers are paying more, commercial operators continue #fishing, and we’re repeatedly told the #fishery is being managed “#sustainably”.'If this is what #sustainability looks like, perhaps we need to rethink what the word means.
'A truly #sustainable fishery shouldn’t require decades of rebuilding while the stock remains well below the level our own management system says it should achieve. It shouldn’t leave us debating whether 10–20% of the original spawning biomass is acceptable, and it most certainly shouldn’t have us celebrating modest improvements while remaining nowhere near the target.'
.....
'Perhaps the real question isn’t why the price has risen, it’s whether we’ve convinced ourselves that #depletion has become an acceptable definition of sustainability.

The fishing ban in the Bay of Biscay will return in 2026 to protect dolphins.
Winter closures in recent years have gained positive results, although the measure will affect around 300 vessels.
