SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Morone americana

SPECIES NAME(s)

White perch

This fishery entered full assessment by the Marine Stewardship Council system in June 2013. Click here to link to the MSC fishery page and to learn more about the MSC fishery certification unit.


ANALYSIS

Strengths

White perch is one of the most abundant invasive species in Lake Erie. Currently “young-of-year” is above the long-term average (Ohio, Ontario).

Weaknesses

White perch is one of the most abundant invasive species in Lake Erie. Currently “young-of-year” is above the long-term average (Ohio, Ontario).
Weaknesses: The stock is not jointly assessed – occasional surveys occur in different parts of Lake Erie – or managed; a TAC is not assigned to the species. Landings data is available only until 2005.
Options: Additional management measures should be in force to reduce Lake sturgeon bycatch by gillnets; a bycatch policy for Ontario’s commercial fisheries is being prepared. A joint assessment and management should be conducted.

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

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). However, a stock assessment is not performed for White perch.

CURRENT STATUS

According to a biological survey in the western basin of Lake Erie (Ohio and Ontario), currently young-of-year is above the long-term average (1,020 fish), at around 1,170 fish (number/hectare). Besides, White perch is considered to be one of the most abundant invasive species by Kocovsky et al. (2011) and also by ODW (2012), in result of a survey conducted in Ohio’s portion of Lake Erie.

Trends

Landings reached 6,940 tonnes in 1991, decreased to around 0,300 tonnes in the late 1990s and increased until 2005, at 2,350 tonnes (Baldwin et al., 2009).

2.MANAGEMENT QUALITY

MANAGEMENT

White perch is a “non-quota species” (Bent & Bier, 2007). Harvest limits and regulations (catch daily limit, fishing temporal seasons, gear type licenses) are established at the state level for the main species in Lake Erie, however no management measures are known to be in place.

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species

Lake Erie hosts eight fish species at risk. The 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 & Jiao, 2011). The impact on the remaining Protected, Endangered and Threatened (PET) species is not known (ECO, 2011).
