STOCKING SCHEDULES - ABBREVIATIONS & TERMS

WARM / COOLWATER


Adult
Typically these fish are in excess of one year of age. These are often feral or wild fish that have been transferred from one location or broodwater to a public fishing location. Fish culture personnel typically do not rear warmwater and coolwater fish to adult size.

Advanced fry
Fry typically absorb their yolk sack in 3-5 days and require live food soon thereafter to grow and flourish. Advanced fry are retained in hatcheries and fed a diet of live brine shrimp for approximately 21 days prior to release. These 21 day old fish are expected to have a survival advantage over 3-5 day old fry.

Conf

Dnst

Elver
Juvenile lifestage of stream or river resident young American eel (catadromous). This lifestage is the first post leptocephalus larval lifestage and is characterized by darker coloring and more voracious feeding behavior.*

Fingerling
Depending upon the species, these fish are 3 or more months in age. To attain this size fish culturists stock fry into fertilized culture ponds or indoor culture tanks and then harvest ponds and distribute them to public fishing waters when they attain requisite size.

Fk
fork

Fry
Typically between 3 and 5 days old. These fish are distributed to public fishing waters at a time soon after hatching while the yolk sac is being absorbed.

Glass Eel (GEEL)
Juvenile lifestage of early ocean returning American eel (catadromous). The leptocephalus larvae are characterized as planktivorous drifting in ocean currents as they enter the lower portion of tidal tributaries.*

Sec., Section, Section No., Section Limits
section number - an internal code used to designate specific reaches of stream sections, defined with upstream and downstream limits. The upper-most stream section is designated number 1.

section limits - specific reaches of stream sections or limits, defined by upstream and downstream limits.

Small fingerling
Small fingerling typically refer to esocids (musky and tiger musky) 3 month or less in age and represent fish "thinned" from production systems to accommodate growth to larger size of esocids that remain. Small finglerlings are typically not produced to meet a specific request. They result from diet and survival experimentation at production levels. Once experimental details are worked out, there availability is diminished. Nonetheless all small fingerling produced are released inot public fishign waters to contribute to esocid fishing opportunities.

Sr

T or Twp

Unt

Up

Upst
upstream

Yearling
Typically these fish represent fingerling fish that have over wintered in a hatchery pond or tank. Typically, fish are over wintered to add size/weight to enhance post-stocking survival. Yearlings are distributed to public fishing waters in spring.
