Feeding ecology of larval and juvenile American shad (Alosa sapidissima) in a small pond Feeding ecology of larval and juvenile American shad (Alosa sapidissima) in a small pond
Release ponds are used as part of a multifacet effort to restore American shad (Alosa sapidissima) in the upper Susquehanna River basin. Little information exists, however, on the feeding ecology of young shad in small ponds. Consequently, we examined feeding ecology and prey selection of 299 larval and 299 juvenile American shad in a small pond during spring and summer. Larval shad...

Pellets versus feces: their relative importance describing the food habits of double-crested cormorants Pellets versus feces: their relative importance describing the food habits of double-crested cormorants
We compared the amount of taxonomically identifiable (diagnostic) fish remains in double-crested cormorant (Phalacrocorax auritus) feces to that exiting the birds via regurgitated pellets. Feces and pellets were collected concurrently during June 1994 from cormorant colonies on Little Galloo Island, eastern Lake Ontario. About 90% of the diagnostic fish remains were found in pellets and...

Estimating losses to predation of recently released American shad larvae in the Juniata River, Pennsylvania Estimating losses to predation of recently released American shad larvae in the Juniata River, Pennsylvania
Predation on recently released larval American shad Alosa sapidissima was quantified in the Juniata River, Pennsylvania, on 10 occasions during 1991 and 1992. Of the four sites examined (the stocking site and 100, 200, and 350 m downstream) predation on shad larvae was highest at the stocking site; 44% of the total estimated losses occurred within this 30-m zone. Percentage predation...

Effects of prey density and short term food deprivation on the growth and survival of American shad larvae Effects of prey density and short term food deprivation on the growth and survival of American shad larvae
Growth and survival of 16-and 18-day-old American larvae (Alosa sapidissima) increased with prey density (0, 500, and 1000 Artemia l−1), though differences were not always significant. Significant differences were not observed in growth parameters and survival for larvae fed 500 v. 1000 Artemia 1−1 in laboratory experiments. Food deprivation for as little as 2 days had significant...

Lake trout rehabilitation in Lake Huron Lake trout rehabilitation in Lake Huron
Efforts to restore lake trout (Salvelinus namaycush) in Lake Huron after their collapse in the 1940s were underway in the early 1970s with completion of the first round oflampricide applications in tributary streams and the stocking of several genotypes. We assess results of rehabilitation and establish a historical basis for comparison by quantifying the catch of spawning lake trout...

Coastal ecosystem decision‐support GIS: Functions and methodology Coastal ecosystem decision‐support GIS: Functions and methodology
To solve coastal resource and environmental issues and handle complex spatial data and information effectively and efficiently, a coastal ecosystem decision‐support geographic information system (GIS) is being developed at the Southern Science Center of the U.S. National Biological Service. With three subsystems, natural resource management, environmental impact assessment, and data and
