SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Perca flavescens

SPECIES NAME(s)

American yellow perch, Yellow perch

Four different assessment units are in the Lake Erie for American yellow perch: 1) Western Basin, 2) Western Central Basin, 3) Eastern Central Basin and 4) Eastern Basin (GLFC, 2012a; 2015). Stock structure is not completely understood; several spawning groups have been detected from genetic analysis, showing little evidence of correspondence with the established assessment units (Sepulveda-Villet and Stepien, 2011).


ANALYSIS

Strengths

The Yellow Perch fishery is well regulated for commercial and recreational fishers in Lake Erie. Yellow perch catches are regulated through possession limits, gillnet mesh size restrictions, quotas and fishery permits. Major commercial fish species such as walleye and yellow perch have been well managed under the quota system for the past 20 years.

Weaknesses

Currently, there is a combined quota of Recommended Allowable Harvest (RAH) for Yellow perch in all 4 management units. But, there is a need to evaluate reference points such as F and exploitation rate for all the 4 management units put together as a single stock for Lake Erie. There is a need to increase management regulations on both sides of Canada and USA for subsistence catches.

Options

There is a need to conduct regular monitoring of stocks and strengthen decision-making process for RAH species. There is a need to conduct a new survey to evaluate harvest of fish by First Nations communities to assist future stock assessments.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

1.STOCK STATUS

STOCK ASSESSMENT

Last updated on 28 December 2012

Lake Erie is divided into 4 Management Units which are managed on both sides of the Lake; Canadian side (Ontario), and on the USA side (States of Michigan, Ohio, Pennsylvania). Yellow perch are caught using gillnets, traps and angling in these 4 Management Units.

Stock assessments are undertaken by the Yellow Perch Task Group (YPTG) of the Lake Erie Committee’s (LEC) that is part of the Great Lakes Fishery Commission (GLFC). The YPTG is comprised of scientists from state, federal and provincial agencies which conduct research on Lake Erie. Scientists use data sets from 1980s to present to conduct stock assessments for the yellow perch stocks harvested on US and Canadian side of the Lake Erie. Assessments used data such as “Fishery harvest, effort, age composition, biological and stock parameters; Survey indices of young of year, juvenile and adult abundance, size at age and biological parameters; Fishing harvest and effort by grid” (YFTG 2012). After examination of catch trends using population models such as Catch-at-age (CAGEAN) analysis and ADMB catch-at-age analyses the committee suggests allowable harvest strategies for the stock across all 4 Management Units. Management agencies then set Recommended Allowable Harvest (RAHs) quotas for the Yellow perch stock in Lake Erie for the next year.

SCIENTIFIC ADVICE

Last updated on 21 February 2011

Existing RAH quotas need to incorporate improved catch estimates from subsistence fishers and there is a need to improve monitoring and estimation of take home catches of sport fishers.

Reference Points

TAC (2011) Total for Lake Erie: 12.650 million pounds
Total Catches for Lake Erie (2011): 9.620 million pounds

Reference points:
Harvest Rate (2011) – Ontario Small mesh gillnets: 134.6
Harvest Rate (2011) – Ontario Small mesh gillnets: 43.8
F (age 3+) Unit 1: 0.397
F (age 3+) Unit 2: 0.207
F (age 3+) Unit 3: 0.067
F (age 3+) Unit 4: 0.083

CURRENT STATUS

Last updated on 21 February 2011

The most recent stock assessment by the Yellow perch task group in 2012, shows that yellow perch is not overfished and overfishing is not occurring on this stock (GLFC 2012a).

Trends

Last updated on 21 Feb 2011

Yellow perch catches have been well managed for the past 30 years under the Recommended Allowable Harvest (RAH) quotas for all the 4 Management Units of Lake Erie. Catches decreased from a high of 8000 tonnes in 1980 to 3000 tonnes by the year 2000, before increasing to around 4000 tonnes in recent years.

2.MANAGEMENT QUALITY

MANAGEMENT

Last updated on 28 December 2012

The fishery is managed under the bi-national Great Lakes Fisheries Commission (GLFC) that joins USA and Canada resources research and management. The TAC is set annually by the Lake Erie Committee’s (LEC) that is part of the GLFC and is based on the RAH, allocated to each of the management areas (reasoned on the lake correspondent area).

Recovery Plans

Last updated on 28 Dec 2012

None are envisaged under the current management plan as Yellow perch stock is healthy and current fishing effort poses minimal risk to the stock. The Yellow Perch stock is managed through Recommended Allowable Harvest (RAH) quotas in Lake Erie.

US/Canada Lake Erie MU1
Canada

The Ontario Ministry of Natural Resources (OMNR) manages Ontario’s commercial fisheries under the bi-national Great Lakes Fisheries Commission (that joins USA and Canada resources research and management) and different state agencies, the Ontario Commercial Fisheries Association (OCFA), the Ontario Fisheries Resource Centre and Aboriginal fishers (ECO, 2011). TAC is redistributed in “amounts of fish for conservation, subsistence and ceremonial use” and split between commercial and sport fisheries by OMNR (ECO, 2011).

COMPLIANCE

Last updated on 21 February 2011

Compliance is relatively good for both recreational and commercial fisheries in Lake Erie.

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species

Last updated on 21 February 2011

Lake Erie hosts eight fish species at risk. Impact on Endangered, Threatened and Protected (ETP) species is not known (ECO, 2011) for most of them.

US/Canada Lake Erie MU1
Canada
Gillnets and entangling nets

Gillnet bycatch is an additional threat for the recovery of the population of Lake sturgeon (Acipenser fulvescens) (Least Concern; 2008 IUCN Red List), especially in the west basin (ECO, 2011; Li and Jiao 2011).

Other Species

Last updated on 21 February 2011

Non-target species, discards and by-catch are not reported from this fishery.

HABITAT

Last updated on 21 February 2011

Gillnets and traps used in this fishery have very low to nominal impact on benthic fishing habitats. Lost fishing gear can cause ghost fishing and such impacts have to be quantified in Lake Erie.

Marine Reserves

Last updated on 21 Feb 2011

There are no reported freshwater protected areas in Lake Erie but some areas are off limits to commercial and recreational fishers during certain periods in the year.

DATA NOTES
  1. Under the reporting system when the last update was conducted, it was difficult to split catches, F, exploitation rate and other limit reference points between Canadian and USA side for all the four Management Units. Exploitation rate values are related to ages 3+ for all four management units put together. TAC and catches values for the years 1989-2012 were taken from Lake Erie Committee – Yellow Perch Task Group annual reports.
  2. Catch data include US and Canada cathces and merge sport and commercial fisheries.
  3. Catch data is fourfold in FSv3 as currently there are four independent profiles with identical datasheet, one for each assessment unit (Western Basin, Western Central Basin, Eastern Central Basin and Eastern Basin), reflecting the current assessment and management system.
