Received this from Bill Bakke, director of the Native Fish Society.
While I understand those who oppose Mr. Bakke and NFS on other anadromous fishery matters this proposal is short sighted and should be of concern.
Current Angling Regulations
North Coast (Necanicum River to Neskowin Creek) Catch and release, flies and lures only. Adopted in 1997.
South Coast (Salmon River south to California line) 2 fish/day, 8-inch minimum, flies and artificial lures only. Regulations were identical to the North Coast until changed in 2001.
Proposed Change: Coastwide, 2 fish/day, 8-inch minimum, flies and artificial lures only. This regulation will be in effect for four years if adopted by the ODFW Commission.
Statement in Opposition:
It is thought that cutthroat (CT) populations above barriers and resident populations in some larger streams are generally healthy. The current thinking is that these resident populations do not contribute to sea-run (anadromous) populations. The upper Nehalem River is an example of a local river that appears to have a healthy resident population although it likely contains anadromous components also. Healthy resident populations should be able to withstand a 2 fish bag limit if it is decided that it is critical to take two 8-inch trout home to eat in order to have had a successful angling experience. I say this assuming that the light angling pressure currently observed on the south coast holds true for the north coast. Apparently, the 2 fish limit is not very attractive to the typical trout angler.
The sea-run cutthroat population, when healthy, can provide a “Blue Ribbon” angling experience for 12-16 inch fish caught near the surface on light tackle using flies or lures. This population is extremely vulnerable to poor ocean conditions caused by El Nino weather patterns that predominated along the Oregon coast from the late 1970s to the late 1990s. Sea-run CT populations crashed but it was not until 1997 that ODFW responded with protective regulations. In all fairness to ODFW, it should be pointed out that this is a difficult fish to inventory and obtain good populations estimates. Ocean conditions have greatly improved over the last 3 or 4 years and it is thought that these populations have improved to some extent.
At my request, ODFW has provided me with a White Paper entitled “Biology, status and Management of Coastal Cutthroat Trout on the North Oregon Coast” that represents their justification for the proposed regulation liberalization. ODFW has a long term (1965-2003) resting pool counts of summer steelhead and spring chinook adults in three Tillamook County rivers. Adult sea-run CT were also noted during these surveys. Recent counts indicate a substantial recovery from the very low counts of the El Nino years. They also have a 6 year data set of smolt trap counts from three North Coast rivers but it does not show any obvious trend toward improving smolt numbers. The report does not discuss whether or not populations are close to carrying capacity or if any perceived improvement is due to improved ocean conditions or restrictive angling regulations.
ODFW has always given considerable emphasis to protecting salmon and steelhead smolts from angling impacts by imposing restrictive minimum size restrictions. This is as it should be. Their report contains considerable discussion of how the proposed 8-inch size limit will continue to provide protection for these smolts but there is no mention at all of protection for sea-run CT presmolts. Most coastal sea-run CT smolts enter the ocean as three or four year old fish greater than 8-inches in length. Under the proposed angling regulations change these CT presmolts will be exposed to a year or two of angling take before their initial ocean emigration. CT smolts only spend two to four months at sea before returning to the river estuaries and accordingly have relatively high (up to 40%) smolt to adult survival rate. Excellent survival rates for salmon and steelhead would be in the 3-6% range. The CT presmolts are too valuable to be targeted as 8-10-inch fish in a consumptive sport fishery.
Many adult sea-run females on their first spawning migration are not mature enough to spawn. These fish are thus exposed to a take fishery as presmolts and two years as adults before getting a chance to spawn. Adult fish have a high (up to 40%) rate of repeat spawning. In comparison a rate of 10% would be considered very high for steelhead. The larger, older repeat spawner females produce nearly twice as many eggs as younger fish. Except at times of extremely high population levels, it appears that the adult fish may be too vulnerable to provide a consumptive fishery.
It seems that the south coast liberalization of CT regulations in 2001 after only three years of protective rules is premature. It seems unlikely that sound biological information would indicate a substantial recovery of 4 or 5 year old adult fish after three years. It would appear that either there was little support that populations were ever depressed or there were some political or social pressures applied.
The opening sentence of the conclusion from ODFW’s aforementioned White Paper does not provide a lot of confidence that the proposed regulation change is based on strong science, indicating a healthy present day sea-run CT population. It reads: “Indicators of abundance and population size of coastal cutthroat trout on the north coast suggest that the population is likely rebounding from historic lows observed over the previous 20 years.” Underlines are added for emphasis.
I also have a concern that ODFW will not be able to react in a timely manner if populations again crash. Given the 4 year regulation cycle, limited population level information, inherent bureaucratic inertia, and a short institutional memory; I feel the fish are better protected with restrictive regulations in place.
I strongly feel that coastal cutthroat, and in particular, sea-run cutthroat should be managed to provide a “Blue Ribbon” fishery on healthy adult populations. A consumptive fishery on 8-10 inch presmolts is not a compatible alternative.
