Harp seals and Cod Questions and Answers SNIP Answers to questions posed by those who've done no research and would like to pretend Canada is 'scapegoating' the seal http://www.dfo-mpo.gc.ca/media/backg...hq-ac01b_e.htm __________________________________________________ ________ Impact of Seal Predation on Cod The 2001 Report of the Eminent Panel on Seal Management concluded that seals consume large amounts of fish throughout Atlantic Canada, but there is much less evidence that this predation is having a major impact on the recovery of most commercial fish stocks. The findings of the report were not conclusive and many uncertainties were acknowledged in providing realistic predictions. The Panel acknowledged that gaining an understanding of the real impact of seals on the recovery of cod is extremely complex and requires an in-depth understanding of the marine ecosystem as well as additional research. Findings highlighted in the report include: The consumption of cod, and some other commercial species, by seals in Divisions 2J3KL and 4RS3Pn is so large that a reduction in seal predation could reasonably be expected to have a substantial effect on the size of these stocks. However, the extent of this reduction would have to be large in order for an impact to be observed. There is not a simple, straight-line relationship between seal predation and the state of fish populations. The interaction between seals, groundfish and other species is complex and variable. For instance, seals eat cod, but seals also eat other fish that prey on cod. Moreover, other factors such as environmental changes and fishing levels must be considered in trying to determine why cod stocks have not yet recovered. The harp seal population has grown to the highest level recorded. Coupled with the fact that the annual TAC has rarely been taken in full, the panel expects a gradual increase in seal numbers if the current management approach is maintained. The current scientific knowledge is insufficient to determine the impact of a seal cull on cod fisheries in the short, medium or long term. Science and resource managers question the value of a cull in a fishery driven by economic market conditions. More importantly, there is no way of knowing how other predators and prey might respond to a decrease in the seal population. Current estimates of cod consumption by seals vary greatly from less than one per cent to more than 20 per cent of diet, depending on the type of seal researched, the time of year and location of the studies. The panel concluded that more comprehensive research needs to be done to more accurately estimate the amount of cod that seals are consuming. __________________________________________________ ________ I see no scapegoating.

He argued that the seal population was exploding - with an estimated 5.2 million harp seals in the North Atlantic at present – and commercial fish stocks were vanishing. ' http://www.indolink.com/displayArtic...d=041304105510 So, let me get this straight. When looking for Canadian Goverment opinions, one should look to 'indolink' an indian news site (Even considering they don't provide a quote) as opposed to say . . . the Canadian Government. Face it pearl, the Canadian Government has been falsely accused of 'scapegoating' seals as the cause of the decline in fish stocks. As far as John Efford goes. Even in the 'indolink' news story, he didn't accuse the seal of being the cause for the decline in cod populations. He simply noted that: 1. The seal population has reached a record high (since recording began). 2. The commercial fish stock is vanishing. Both of which are true. It's not up to you to put words into his (or anyone elses) mouth, like you do so often. |

'We could benefit from some new thinking on seals, and
a holistic reassessment of the roles played by seals in marine environments must precede any experiments or new initiatives that involve deliberately reducing their numbers. Seal research has been an earlier focus of this committee(3), and is currently at the forefront again, with the Minister’s recent announcement of $6 million for a study on the experimental use of “seal exclusion zones” in an effort to aid the recovery of depleted cod stocks. Seal research is fine, but any such proposed “experiments” must not be conducted without the use of the appropriate scientific “controls.” And I strongly suggest that this type of experimental seal research not be undertaken before completing a holistic reassessment of the roles played by seals in the larger marine ecosystem. Seals have long lived in marine environments and their overall contribution to these systems cannot have been negative (or else they would have been eliminated millions of years ago(4)). Therefore, although it is counterintuitive to many, the removal of more seals at this point may not be without added risk to the health of today’s declining fish stocks. Positive contributions to ocean health that can be seen to be made by seals include the production of zooplankton (via the excretion of vast numbers of live worm eggs(5)), and the scavenging consumption of dead or dying fish that might otherwise undergo bacterial decay on bottom, with a resulting dangerous depletion of oxygen from the water. In an oxygen stressed, low zooplankton aquatic situation, air-breathing/zooplankton-excreting marine mammals such as seals may therefore perform a unique system-stabilizing role by consuming dead or dying fish, while not removing oxygen from the water or succumbing to hypoxia themselves. These observations are intended to suggest some directions in which the holistic effect of seals (and other marine mammals) on ocean health might usefully be investigated. They also serve as a warning of the nature of the adverse impacts on the marine environment that may result from the removal of seals (less zooplankton, less oxygen). Seals are an integral part of life in a healthy ocean, and their actions today appear only to be part of what naturally occurs when such a living system tries to recover from damage inflicted on it. As fish eaters, the seals will actively work towards the stabilization of an ocean environment that supports fish…but the same cannot be said for the bacteria that will break down dead fish in the absence of larger animal consumers such as seals. The recent decision to allow fishermen to shoot “nuisance seals,” as well as the planned implementation of “seal exclusion zones” in Atlantic Canada should be carefully reconsidered in this light. ..' http://www.fisherycrisis.com/DFO/commons.htm |

The majority of groundfish stocks off the province’s coasts have not recovered to pre-moratorium levels, and it is speculated that the federal government will this year once again close some cod fisheries which were reopened in the late 1990's. "There is no doubt that seal predation on groundfish is impeding the recovery of those stocks," added Minister Reid. ..' http://www.gov.nf.ca/releases/2003/fishaq/0203n03.htm but not when the IFAW does it . . .
