Grey seals eat into another fish population in the Gulf of St. Lawrence
Grey seals are eating into another fish species in the southern Gulf of St. Lawrence, driving a serious decline in the abundance of yellowtail flounder, according to a new report from Fisheries and Oceans Canada (DFO). Federal scientists assessed the flatfish species in the southern gulf over the past 25 years up to 2020 and projected the population to 2030. The results are stark. The number of yellowtail flounder six-years and older is believed to have declined by 95 per cent since the mid-1980s. There is a 100 per cent probability the population will remain in the critical zone where serious harm occurs whatever the level of commercial fishing, the report says. >click to read< 08:39
How Newfoundland’s wild fisheries have gone from plentiful to pitiful – How did we get here?
The headline in the daily paper at the end of January 2019 had said it all: Cod recovery still far off: DFO. In the case of cod, the same factors that had contributed to a hopeful comeback — thriving capelin and warming waters — had since swung in unfavourable directions. Fewer capelin prey and changing environmental conditions did not bode well for cod. Now, in 2021, the prognosis for the cod population, capelin and the environmental 
conditions remains no better. How did we get here? DFO science shows several factors are predominantly to blame for declining cod and capelin populations, including: natural causes, especially lack of capelin prey in the case of cod; high predation, particularly from fish (more so than seals), in the case of capelin; and warming ocean waters, among other environmental factors. >click to read< 08:26
