|Species mix/Fishing Opportunities-A fish
community can be described by its species mix, those qualities(stability,
balance, sustainability, and diversity) which enable it to persist and by
measures of fishing opportunities(human needs) it offers. Generally, public
attention (and it follows the agencies attention) is focused on harvest.
|Habitat- fish numbers and species
composition are strongly influenced by habitat features---for example most of
Huron is deep and cold except for some embayments---features that are beyond
|Management- opportunity for management
of fish populations and habitat is limited. Habitats can be rehabilitated to
some degree nearshore and in tributaries but not offshore. Beyond the near
shore managers can exert an influence through fishing regulations, stocking and sea lamprey control. However,
management actions are inexact. Stocking for example can produce short term
gains that are difficult to sustain long-term.
have had little influence on the rate of introduction of exotics. Probably
the greatest impacts(alteration of the food webs) by exotics are just
beginning to be understood.
|2000 and 2010 Fish Community Objective Reviews-
because FCOs for an entire lake cannot be taken to a high degree of
exactness, fishery management
opportunities are limited, and management initiatives aimed at achieving objectives will have a large
experimental component, 2000 and 2010 are priority years for review.
