In order to compare differences in diet between habitat types along the transect and maintain a statistically viable sample size for each species, three dominant sciaenids captured during 2006 were selected; Bairdiella chrysoura, Cynoscion regalis
, and Micropogonias undulatus (Vasslides 2007).
Fish density in the shore zone (Table 1) was dominated by Atlantic silverside (Menidia menidia, 51%), bay anchovy (Anchoa mitchilli, 32%), weakfish (Cynoscion regalis
, 4%), and bluefish (Pomatomus saltatrix, 2%).
In this river system, 3 of the dominant pelagic predators are bluefish (Pomatomus saltatrix), striped bass (Morone saxatilis), and weakfish (Cynoscion regalis
Finally, increased flow of seawater into Little Bay and the Sedge Islands has enabled large numbers of weakfish (Cynoscion regalis
), bluefish (Pomatomus saltatrix), striped bass (Morone saxatilis), and other piscivorous fish to enter the area, which has stimulated considerable recreational fishing activity, leading to additional habitat loss and alteration due to heavy boat traffic.
Weakfish (Cynoscion regalis
Bloch and Schneider: Sciaenidae) occur along the U.S.
Abstract--From 2008 through 2010, the diets of 3 sciaenid species, the weakfish (Cynoscion regalis
), southern kingfish (Menticirrhus americanus), and Atlantic croaker (Micropogonias undulatus), were examined.
This lack of key information applies to the economically and ecologically important sciaenid weakfish (Cynoscion regalis
), which is seasonally distributed in estuaries and coastal habitats along the Middle Atlantic Bight, where it feeds and spawns.
From May to October in 2006 and 2007, we measured residencies of ultrasonically tagged age-1+ Striped Bass (Morone saxatilis; n=46), age-0 and age-1+ Bluefish (Pomatomus saltatrix; n=45 and 35) and age-1+ Weakfish (Cynoscion regalis
; n=41) in a small estuarine tributary in New Jersey with 32 ultrasonic receivers to monitor movements and sensors to measure habitat resources.
Group E comprises fishes from all 3 regions: Spotted Seatrout (Cynoscion nebulosus) from Atlantic and GOM populations, as well as Weakfish (Cynoscion regalis
), Spotfin Croaker (Roncador stearnsii), and Yellowfin Croaker (Umbrina roncador).
Abundance and stomach contents of seasonally co-occurring piscivores were examined to determine overlap in resource use for Summer Flounder (Paralichthys dentatus; 206-670 mm total length [TL]), Weakfish (Cynoscion regalis
; 80-565 mm TL), Bluefish (Pomatomus saltatrix; 55-732 mm fork length [FL]), and Striped Bass (Morone saxatilis; 422-920 mm FL).
