A Tale of Two Timescales: Using Otolith Microchemistry to Improve Our Understanding of Alligator Gar Movement in the Lower Trinity River, Texas

Fisheries Outstanding Technical Paper
SEAFWA Journal Volume 6, March 2019

Telemetry-based study of alligator gar (Atractosteus spatula) movement in the lower Trinity River, Texas, indicated that fish primarily re- mained within discrete home ranges less than 60 river kilometers (rkm), supporting the potential for local-scale management. However, the temporal scale of inference was limited (22 months), which may inadequately represent fish movements and home range size at the lifetime (i.e., ≥50 years) scale. Therefore, we used otolith microchemistry to examine the long-term movements of alligator gar (n = 59; total length range 1152 to 2420 mm, age range 4 to 60...


A Review of Marine Recreational Hook Regulations in the United States: Accessibility, Incorporation of Science, and Recommendations

SEAFWA Journal Volume 3, March 2016

The effects of fish-hook type on hooking location and post-release mortality of recreationally and commercially targeted fish species have been well studied. We examined how fisheries management agencies along the coastal United States had incorporated fish-hook data into fisheries regulations and how visible and accessible those regulations were to anglers. We reviewed state recreational hook regulations on natural resource agency websites of 23 states. To assess the accessibility of hook regulations to anglers, we conducted an online survey that was distributed by email to participants...


Comparison of Growth, Abundance, and Emigration of Two Morone Hybrids in a High Flow-through Oklahoma Reservoir

SEAFWA Journal Volume 1, March 2014

Hybrid striped bass (Morone saxatilis x Morone chrysops) are commonly introduced in southeastern U.S. reservoirs to create a sport fishery and as a means of utilizing abundant shad (Dorosoma spp.) populations. The Oklahoma Department of Wildlife Conservation (ODWC) has historically stocked the common-cross hybrid (M. saxatilis female x M. chrysops male; hereafter, common HSB) rather than the reciprocal-cross hybrid (M. saxatilis male x M. chrysops female; hereafter, reciprocal HSB). Due to concerns over downstream emigration of stocked fish from reservoirs, common HSB have mostly been...
