We collected and electrophoretically analyzed a total of 558 fish from eight locations along the Pacific Coast of Russia. We successfully screened 44 enzyme-coding loci: 14 loci were polymorphic at the 0.95 level in at least one collection, an additional eight were polymorphic at the 0.99 level but not at the 0.95 level, and the remaining 22 were either monomorphic or exhibited only very rare variation in these collections. Contingency χ2 tests using the 23 most variable loci revealed significant heterogeneity among all eight collections (p = 0.028) but little or no significant heterogeneity among collections within areas (northeastern Kamchatka peninsula, p = 0.180; southwestern Kamchatka, p = 0.533; and mainland adjacent to the northwestern Sea of Okhotsk, p = 0.071). Multidimensional scaling and minimum spanning tree analyses using genetic distances among collections indicated that geographic proximity of spawning sites was not associated with genetic similarity. The eight odd-year pink salmon (Oncorhynchus gorbuscha) collections from Russia were compared with 16 collections from North America (southeastern Alaska, British Columbia, and Washington) using data for 33 loci. The Russian populations differed from the North American populations in their patterns of allelic variation at many loci. The amount of genetic differentiation among populations from different rivers in Russia was comparable to that seen within similar-sized areas in North America.

Recent Developments

The simple-Petersen estimator is a well-known mark-recapture method to estimate animal abundance. Two key assumptions are equal catchability in both samples and complete mixing of tagged and untagged animals. If these are violated, severe bias can occur. The stratified-Petersen estimator can be used to account for some of the heterogeneity in catchability or mixing. In this paper, we first review recent developments in the stratified-Petersen experiment for fisheries audiences and demonstrate some of the practical problems that can occur that have not been discussed in the theoretical literature. Second, we present a case study to estimate the gross escapement of Fraser River pink salmon (Oncorhynchus gorbuscha) in 1991. The motivation for this study is a discrepancy of over 5 million fish between the estimates as derived by the Pacific Salmon Commission (PSC) (7.5 million fish based on a hydroacoustic method) and the Department of Fisheries and Oceans (DFO), Canada (13.0 million fish based on a mark-recapture method). One hypothesis put forward was that the discrepancy may be due to the use of a pooled-Petersen estimator when there is differential migration over time. The stratified-Petersen model suggests that little of this discrepancy can be explained by differential migration.

Degree Of Differentiation

Meristic and morphometric measurements were taken from 33 male and 44 female mature pink salmon, Oncorhynchus gorbuscha, collected in three Lake Superior tributaries in Marquette County, Michigan. Significant sexual differences were found for eight characteristics in males and two in females. The male fish had a greater degree of differentiation in the head and hump regions; females had larger and longer anal fins. The Lake Superior fish were found to have shorter bodies, larger and longer fins, and more exaggerated development in the male head and hump than has been reported for the Pacific populations.

Saltwater-acclimated, coded-wire tagged, and adipose fin clipped pink salmon (Oncorhynchus gorbuscha) fry were exposed for 10 days to seawater (control) or 25-54 μg·L-1 (low dose) or 178-349 μg·L-1 (high dose) of the water-soluble fraction (WSF) of North Slope crude oil. The WSF was composed primarily of monoaromatics and was acutely lethal to the fry: 96-h LC50 ranged from 1 to 2.8 mg·L-1. After exposure the fry (30 000 per treatment) were released into the Pacific Ocean to complete their life cycle. The experiment was replicated in 1990, 1991, and 1992. There was no consistent significant dose-dependent effect of the 10-day exposure to the crude oil WSF on growth of the pink salmon prior to their release. Adult pink salmon from this experiment were captured in fisheries and also recovered from their natal Quinsam River, British Columbia. Pink salmon from each treatment group were recovered in similar numbers. Exposure of populations of fry to the WSF of crude oil and release to the Pacfic Ocean did not result in a detectable effect on their survival to maturity. Fry from all treatment groups incurred typically high mortality following release, and there were no discernible effects on survival that were attributable to exposure to the WSF of crude oil.

Model Fish

The homing migration of pink salmon (Oncorhynchus gorbuscha) from the open ocean towards their natal rivers was studied by a mathematical model using data from tagging experiments. In this model fish migration was considered to be the resultant of fish orientation and random movement. The mean migration speed and dispersion coefficient (an index of random movement) evaluated from regression analysis were 19.6 km∙d−1 and 739 km2∙d−1 for the North American group and 47.1 km∙d−1 and 863 km2∙d−1 for the East Kamchatkan group, respectively. The results indicated that pink salmon migration has more oriented movement than had been suggested by a previous computer simulation by other workers. The results also indicated that there is a distinct difference in the migratory behavior of North American and East Kamchatkan pink salmon.

The origin and subsequent elaboration of the mesonephric tubules from condensation of cells derived from the intermediate cell mass is described from the earliest appearance of condensations to the differentiated stage in the year-old fingerling. It is noted that both the pronephric and mesonephric kidneys are present together for a considerable period of the early life of the pink salmon, though it is unlikely that both function simultaneously.
