There was the rare, purely conservationist measure such as Newfoundland’s 1858 law regulating the mesh size in the herring fishery. But it was difficult to think of overfishing when the catches were getting bigger every year. Catches were improving not because the stocks were plentiful but because fishing was getting more efficient. Nevertheless, as long as better fishing techniques yielded bigger catches, it did not seem that the stocks were being depleted.
The indomitable force of nature was a fashionable nineteenth-century belief. The age was marked by tremendous optimism about science. The lesson gleaned from Charles Darwin, especially as interpreted by the tremendously influential British scientific philosopher Thomas Henry Huxley, was that nature was a marvelous and determined force that held the inevitable solutions to all of life’s problems. Huxley was appointed to three British fishing commissions. He played a major role in an 1862 commission, which was to examine a complaint of driftnet herring fishermen, who said that longliners were responsible for their diminishing catches. The fishermen had asked for legislation restricting longlining. But Huxley’s commission declared such complaints to be unscientific and prejudicial to more “productive modes of industry.” The commission also established the tradition in government of ignoring the observations of fishermen. It reported that “fishermen, as a class, are exceedingly unobservant of anything about fish which is not absolutely forced upon them by their daily avocations.”
At the 1883 International Fisheries Exhibition in London, which was attended by most of the great fishing nations of the world, Huxley delivered an address explaining why overfishing was an unscientific and erroneous fear: “Any tendency to over-fishing will meet with its natural check in the diminution of the supply, ... this check will always come into operation long before anything like permanent exhaustion has occurred.”
Considering the international impact of Huxley’s work in the three commissions, it is disturbing to note that he once explained his participation in these paid appointments by saying, “A man with half a dozen children always wants all the money he can lay hands on.”
For the next 100 years, Huxley’s influence would be reflected in Canadian government policy. An 1885 report by L. Z. Joncas in the Canadian Ministry of Agriculture stated:
The question here arises: Would not the Canadian fisheries soon be exhausted if they were worked on a much larger scale and would it be wise to sink a larger amount of capital in their improvement?
... As to those fishes which, like cod, mackerel, herring, etc. are the most important of our sea fishes, which form the largest quota of our fish exports and are generally called commercial fishes—with going so far as to pretend that protection would be useless to them—I say it is impossible, not merely to exhaust them, but even noticeably to lessen their number by the means now used for their capture, especially if, protecting them during their spawning season, we are contented to fish them from their feeding grounds. For the last three hundred years fishing has gone on in the Gulf of St. Lawrence and along the coast of our Maritime Provinces, and although enormous quantities of fish have been caught, there are no indications of exhaustion.
Joncas supported this assertion by referring to a British Royal Commission in which Huxley
