Thousands of dead fish wash up in a harbor in Mississippi, USA

Fish Kill Alert
Thousands of dead fish made quite a smelly mess at the Pass Christian Harbor. 
 
WLOX News received complaints from residents who were disgusted by the fish kill. Some of the dead fish may have washed away, but we found many still floating along the southwest corner of the new harbor. 
 
The vast majority of the fish are pogies or menhaden; small oily fish which are commercially harvested for a number of products. No word yet on what caused the fish kill, or if the pogies came from a broken net on a commercial boat.
 
The Mississippi Department of Marine Resources did investigate the fish kill. According to the DMR, it appears to be a low oxygen event that caused the fish to die. It seems the fish kill was limited to that area in and around the harbor since there were no other reports of dead fish elsewhere.

Masses of dead anchovy wash up on the coast of Chanaral, Chile

Masiva varazón de anchovetas en playa de Chañaral preocupa a Sernapesca Atacama
Sernapesca staff and Navy monitor a varazón anchoveta in the Las Pools, 20 kilometers south of Chañaral, where about 250 kilos resource is found dead on the shore.
 
In addition, 500 kilos more of the species remain trapped by the low tide in a sector existing natural pools in the marine area.
 
The regional director of Sernapesca Atacama, Guillermo Mery, said there already staff working in the sector.
 
“Officials were up there next to the Port and say that there are approximately 250 kilos of beached, dead resource, however there are some 500 kilos that are in a paddling pool and who is alive and who could be released with the tide that is eight, therefore, they will be monitoring the place, “he said.

Thousands of dead fish wash up ‘causing shock’ on a lake in Alberta, Canada

Fish Kill Alert
News of a major fish kill that occurred at Stoney Lake this past week came as a sad shock to residents and anglers alike.
 
Ray Makowecki, a fisheries biologist and local resident, confirmed that thousands of fish – including large numbers of yellow perch of all age classes, including perch in the 30 cm size, as well as pike and burbot – were found on the shore and on the lakebed and floating in the lake last week.
 
He said he received a call from a resident, alerting him to the fish kill, and came to the lake to confirm the news with his own eyes.
 
“Jeepers, we just couldn’t believe it. A lot of people I talk to, they feel like they lost a brother,” said Makowecki, who is also the Alberta Fish and Game Association Zone 5 Fisheries Director.
 
While fish kill has been known to happen in Alberta, this kill at the local lake hit close to home for hundreds of fishing enthusiasts, he said, adding, “It’s such a great fishery for so many people.”
 
But while the location is a popular fishing spot, he notes the fact there were dead fish in the thousands suggests that the harvesting from anglers had not significantly reduced the population of perch.
 
In late June, Stoney Lake came under a blue-green algae advisory, with plants growing and accumulating over the summer. That blue-green algae was noticeable earlier in the past week, but with cloudy days cutting off sunlight, the plants died, decaying very quickly and using up the dissolved oxygen in the water, explained Makowecki.
 
“The result was low oxygen for a few hours and that was enough to kill fish. The water looks very clear after these events with little blue-green algae present.”
 
The fish counts in some areas averaged 60 perch per metre of shore, with less pike and burbot were observed.
 
When asked how the kill affected the fish population left at Stoney, Makowecki said that the fact that there were large numbers of young small perch suggested this was a “significant kill,” since usually small-sized fish are able to survive lower oxygen better than large-sized fish.
 
Makowecki noted there are several pressures on lakes, including farming, road building, campsite and cottage development.
 
“There’s always a bit of organic – over time, it produces lots of fish. If you produce too much, then all of a sudden, bingo, something like this happens,” he said. “It’s a real pity.”
 
He notes fish habitat protection is the most important factor in managing fish resources and urges that people do whatever they can to reduce nutrient build-up in the lakes, when it comes to fertilizers, garbage, sewage, eroding soils and sediment, etc.
 
The summer kill of fish at Stoney Lake will likely come up at a meeting scheduled for Sept. 7 at Lac Bellevue Hall to discuss managing fish resources in Alberta. Makowecki urged interested people to come to the meeting, which starts at 7 p.m.
