Dick Grachek responds to “Cod stocks on south coast of Newfoundland ‘OK but not great’

cod-fish-852From the above linked article posted on Fishery Nation.com: “The spawning stock is now between the ages for four and seven years, which [lead researcher Rick] Rideout called a ‘pretty restricted’ age.” Click here to read the article “Basically, fish are not surviving to those older ages, they’re coming into the stock … but they’re not surviving to older age, and again, that’s a big concern.” Then abandon MSY management! A majority of younger fish comprising the spawning stock is a function of Maximum Sustainable Yield management (MSY). This MSY management balances the numbers of larger spawning fish taken out of a stock against the numbers of individuals of smaller younger fish entering the stock or “recruitment”—guess what, this yields a highly unstable stock of smaller younger fish.

Cod stocks on south coast of Newfoundland ‘OK but not great’, says researcher

cod-fishA new study into the state of cod stocks off the south coast of Newfoundland and Labrador shows a decline and high mortality rates. Lead researcher, Rick Rideout, says while stocks aren’t in terrible shape, there is reason for concern. “3PS cod is currently what we would call in the cautious zone … it’s certainly below the target of where fisheries management would like the stock to be,” said Rideout. “We’re okay, but we’re not great.” “Our estimates of mortality are really high right now, as high as we’ve seen in monitoring this stock,” Read the rest here 10:24

WEEKEND FOCUS: Warming waters and the Gulf of Maine’s fate

gulf of maine warmHeadlines around that great body of water, cradled inside of Cape Sable Island to the north and Cape Cod in the south, screamed alarm this fall about a pending ecosystem collapse brought on by climate change. Most of those headlines linked back to a study by Andrew Pershing, chief scientific officer at the Gulf of Maine Research Institute, published in October in the journal Science. In it, Pershing attributes the non-recovery of cod stocks to the Gulf of Maine having warmed faster between 2004 and 2014 than 99 per cent of all other saltwater bodies on Earth.

Scientists say Newfoundland’s cod stocks are coming back. Can we get it right this time?

Sometimes, it seems as if cod is all anyone talks about, inside the Cupids Legacy Centre and on the streets of St. John’s, where cab drivers and tattooed twentysomethings still talk about family fishing rights. So when scientists announce the cod is coming back, it’s big news. It rubs salt into old wounds throughout Atlantic Canada. And it raises questions: Can we get it right this time? If the moratorium is lifted, can we find a way to manage the fishery sustainably? Read the rest here 17:34

Oh Canada! One department says cod is endangered while another recommends more be caught

msFish harvesters and DFO representatives met in Clarenville on Tuesday for a groundfish advisory committee meeting; a chance for fisheries scientists to give their findings and hear from fish harvesters about the state of the resource. The scientists told the 25 to 30 assembled fish harvesters that the Atlantic cod population in 3Ps, an area that includes Placentia Bay, is growing and they’ll recommend the department raise the total allowable catch (TAC) by 15 per cent. Their recommendations come shortly after a report by the Committee on the Status of Endangered Wildlife in Canada (COESWIC) recommending Atlantic cod be placed on a list of endangered species.

Two variations so far – “Canada’s cod, and many other depleted fish, unlikely to recover” and “Study offers bleak outlook for fish recovery”

By Margaret Munro, Postmedia News – Canada’s once bountiful cod stocks are not likely to bounce back, according to an international study on the dangers of overfishing. “Here we are more than 20 years after the cod was effectively depleted, and according to our analysis, the recovery of the cod stocks is highly improbable,” says fisheries scientist Jeffrey Hutchings at Dalhousie University, co-author of the study published in the journal Science on Thursday….at the end of the article: “Ecosystems change,” says Hutchings, noting how seals, herring and mackerel now fill some of the gaps left by Canada’s cod collapse. (which part does he not understand?) contined

Aly Thomson, The Canadian Press HALIFAX – The recovery of overexploited fish populations such as cod has been slower than expected and many depleted stocks may never be able to bounce back, a new study says. continued

It would be great if our Canadian friends would leave comments about this. BH

How about some common sense Dr. Hutchings? New data from DFO suggests seals eat twice as many cod.

INGONISH — No one is sure yet whether grey seals are continuing to threaten recovery of the cod stocks in the southern Gulf of St. Lawrence, but the seals are there and the fish are not. And new data strongly suggests seals aren’t helping the cod. Seals, eating the softer belly meat and leaving the heads, could be consuming much more cod than figures indicate. Previous data suggested a male grey seal’s diet was up to 24 per cent adult cod. Hamill’s new data suggests adult cod could be up to 60 per cent of the male grey seal’s winter diet. That’s more than double the number that was available to the Senate committee when it recommended a cull. continued
