Table 1 was constructed using information from descriptions of the history of the commercial fishery of Lake Erie. Upon reviewing Table 1 three trends become apparent. Firstly, the market constantly grew, spurred by greater demand during the war of 1812, the American Civil War, and the Second World War. The expansion of the railway system, improvements in communications and transportation, and innovations in fish processing all contributed to the ability to meet increased market demand. Secondly, those who were fishing constantly introduced new and more efficient technology for capturing fish. Thirdly, the market demand and increasing fishing technology continue to change the fish populations and species composition of Lake Erie.

1. Fishing effort
2. Environmental modification
3. Exotic species
As the demand for fish grew, larger boats were employed to set and service the nets. These boats required a safe harbour from the frequent Lake Erie storms. The Lynn River, where it empties into Lake Erie at Port Dover, provided the best protection of any natural harbour in Norfolk County. Consequently, the majority of the fishing activity has been undertaken from this harbour. Aside from the relatively small hoop and seine fishery in the Inner Bay, Port Dover is the only active commercial fishing port in Norfolk County today.
From the late 1800's to the late 1920's the fishery was dominated by Blue Pike (See Appendix 1 for scientific names) and Lake Herring (Figures 2-4). Following the Lake Herring population crash in the late 1920's, fishing effort was then concentrated on Blue Pike and Lake Whitefish until both species experienced a population crash during the 1950's (Figure 5). Blue Pike, now presumed extinct in Lake Erie, (Hatch et al. 1990) accounted for over two-thirds of the total catch in 1950 (Figure 6). Fishing effort was then directed towards Yellow Perch and Rainbow Smelt (Figure 7). By 1980 the fishery was dominated by the harvest of Rainbow Smelt (Figure 8). Between 1980 and 1990 the Rainbow Smelt harvest declined by about 1,700,000 kgs. This decrease is reflected in the percentage increase in Yellow Perch, Walleye, White Bass and White Perch in the total harvest of Norfolk County fish (Figure 9).
The Norfolk County commercial fishery has changed substantially over the decades. The fishery was considerably more diverse in the early years. In 1901 eight species of fish accounted for at least 1% of the total harvest respectively (Figure 3). By 1980 the fishery relied on only two species, Yellow Perch and an exotic species, Rainbow Smelt (Figure 8). Another invader, White Perch, has shown substantial population growth in the last ten years. Both the Yellow Perch and Smelt are now experiencing stress.

"These (time periods) were arbitrarily selected so that changes within periods could possibly be attributed to similar stimuli or stressors, making interpretation easier. This approach was partly successful, although the interpretations are admittedly sketchy." (Whillans, 1979)
The results of his research on fish community transformation in the Inner Bay are presented in Table 2.
|Period||Transformation||Cause of Transformation|
|1868-1877||-increase of Muskellunge
-decline of Northern Pike
|An escalation of pound netting at the mouth of the Inner Bay captured proportionally more Northern Pike than Muskellunge. The Pike were more widley distributed than the Muskellunge, that tended to concentrate along the soutern shore of the bay.|
|1880-1889||-decline of Northern Pike and Yellow and/or Blue Walleye||Both Northen Pike and Walleye were exploited by the seine fishery and suffered some stress, especially walleye which was a preferred food fish. The mouth of Big Creek was diverted through a dredged channel for lumbering and the rockey spawning beds were likely silted-up due to deforestation. Aquatic vegetation was choking up the waterway.|
|1892-1910||-increase of Carp and White Bass
-decline of Walleye, Smallmouth Bass, Largemouth Bass, Northern Pike, Yellow Perch, Whitefish, Sturgeon, Herring and Blue Walleye.
|The decreased abundance of Inner Bay fish especially the offshore migrant; Whitefish, Sturgeon, Herring and Blue Pike, appeared to be associated with peaking gill net activity. The decline of Walleye and Yellow Perch was attributed to the construction of a dam near the mouth of Big Creek which barred access to spawing localities. A shift in commercial seining effort to the south shore of the bay may have depleted stocks of Lange and Smallmouth Bass which spawned primarily along that shore. White Bass and Carp may have proliferated in responses to the declines of the other species.|
|1924-1937||-increase of Sea Lamprey
-decline of Strugeon, Muskellunge and Walleye.
|Lake Sturgeon suffered from intense commercial fishing pressure. The Muskellunge population declined severely while not under any fishing pressure and Walleye population fell when fishing effort remained relatively steady. In the later 1920's, a causeway, which cuts across Big Creek marsh and provides reseidents of Long Point with quick access to the mainland, was constructed. The only opening in the causeway is a small bridge which allows the passage of Big Creek. Both Walleye and Muskellunge relied, at least partially, on the marsh of spawing and juvenile habitat. The causeway may have disrupted the spawning of the adults and the survival of juveniles. The marsh plant growth may have been altered due to the input of high phosphorus agriculture fertilizers in the surrounding watershed.|
|1943-1955||-increase of Whitefish and Herring followed by collapse
-decline of Smallmouth Bass followed by increase
-collapse of Walleye and Blue Pike
-decline of Rock Bass, Crappies, Smelt, Alewife, Rainbow Trout and Goldfish
|Whitefish and Herring stocks recovered breifly, then collapsed, due primarily to commercial exploitation. Walleye and Blue Pike also succumbed to intense fishing pressure. Smallmouth Bass intitially declined but subsequently recovered, following enforcement of a longer closed season during the spawning period.|
|1958-1969||-increase of Yellow Perch, White Sucker, Rock Bass and Crappies
-decline of White Bass and Smallouth Bass, Bullheads, Catfish, Bowfin, Pumpkinseed
-initial increase of Carp followed by decline
|The increasing nutrient enrichment of the bay may have contributed to the greater relative abundance of Carp, Perch, Suckers, Rock Bass and Crappies. The decline of Smallouth Bass may be attributed to an increase in sport fishing pressure. The development of a larket for live fish may have been contributed to the decline of the liv market spcies; Bullheads, Catfish, Bowfin, Pumpkinseed and Carp.|
|1970-1979||-decline of Smallmouth Bass
-increase of Largemouth Bass, Yellow Perch, White Sucker, Rock Bass,Cra ppies, Alewife, Bullheads, Catfish, Bowfin, Pumpkinseed, Gizzard Shad, Freshwater Drum and Northern Pike.
|Smallmouth Bass suffered from continues sports fishing pressure and perhaps an increase in water temperature. Warmer water, nutrient enrichment and increase of aquatic vegetation was most likel responsible for the increase in the large number of warm water species.|
Of particular interest to this report are the results of the Nanticoke Fish Study's research on fish migration and movement. Over eight thousand fish were tagged and released at trapnet locations in Nanticoke from 1981 to 1983. Close to 4000 Yellow Perch were tagged and released at other locations in Long Point Bay in 1981 and 1982. About 7.5% of these fish were later recaptured in OMNR trap nets, commercial gill nets and by sports fishermen. The study revealed interesting information on fish movement in the Long Point Bay area.
During the spawning period Rock Bass populations along the northeast shore of Lake Erie, migrated 35-40 km to spawning grounds in the shallow and protected waters of Inner Bay, and then returned to their original grounds (Figure 12).
In summary, it is evident that Long Point and Inner Bay are of enormous importance to the fishery of Lake Erie, and indeed to the fisheries of the Great Lakes. The bay and its marshes provide suitable spawning and nursery habitat for local fish populations, as well as fish communities in Lake Erie's eastern and central basins. (MacGregor and Witzel, 1987) It is very difficult to predict the future of the Lake Erie fishery. It is likely we never will completely understand the interactions that drive the present fishery. Recognizing the aforementioned management limitations, and the inherent inability to control productivity, perhaps the time has arrived to pursue seriously a management approach to the fisheries of Lake Erie that is more closely linked to ecosystem principles and sustainable use. The management approach should be more finely tuned to the needs and desires of the approximately 13 million people living in the surrounding watershed.
