James M. Long, PhD
Unit Leader - Oklahoma Cooperative Fish and Wildlife Research Unit
In 2009, moved to Oklahoma as an Assistant Unit Leader and became Unit Leader in 2016. Jim's research focuses on management-driven questions related to the process of fisheries management, social dimensions, early-life history of fishes, and effects of invasive species on aquatic communities. Over the past decade, Jim has been particularly engaged in issues related to black bass diversity, highlighting the conservation needs of these endemic and iconic species. Jim uses Geographic Information Systems (GIS) and side-scan sonar technology to address research needs in a wide variety of aquatic ecosystems. Jim is also actively engaged in applying novel tools to better understand otolith morphology and composition to elucidate age, growth, and development in fishes. Jim teaches a graduate level course in Social Dimensions in Aquatic Ecology.
Jim grew up in the Ozarks of southwest Missouri and received a PhD from Oklahoma State University in 2000. Afterward, he went to South Carolina as a Fisheries Research Biologist investigating fish community structure in tidal freshwater wetlands. From 2002 to 2009, Jim worked with the National Park Service as the Fishery Biologist for the southeast region.

Diet composition of age-0 fishes in created habitats of the Lower Missouri River
Channelization of the Missouri River has greatly reduced the availability of shallow water habitats used by many larval and juvenile fishes and contributed to imperilment of floodplain-dependent biota. Creation of small side channels, or chutes, is being used to restore shallow water habitat and reverse negative environmental effects associated with channelization. In the summer of 2012, the U.S.

Otolith marking of juvenile shortnose gar by immersion in oxytetracycline
Oxytetracycline (OTC) has been used to mark a variety of fish species at multiple developmental stages; however, there is little information on batch-marking Lepisosteidae. Juvenile Shortnose Gar Lepisosteus platostomus (53 ± 3 mm TL) were seined from an Oklahoma State University research pond and transported to the Oklahoma Fishery Research Lab. Juvenile Shortnose Gar were exposed to a range of O

Comparative precision of age estimates from two southern reservoir populations of paddlefish [Polyodon spathula (Walbaum, 1792)]
The aim of the study was to determine whether location and sex affected the age precision estimates between two southern, reservoir populations of paddlefish [Polyodon spathula (Walbaum, 1792)]. From 589 paddlefish collected in Grand Lake and Keystone Lake, Oklahoma in 2011, ages from dentaries were estimated using three independent readers and precision was compared with coefficient of variation

Validation of daily increments periodicity in otoliths of spotted gar
Accurate age and growth information is essential in successful management of fish populations and for understanding early life history. We validated daily increment deposition, including the timing of first ring formation, for spotted gar (Lepisosteus oculatus) through 127 days post hatch. Fry were produced from hatchery-spawned specimens, and up to 10 individuals per week were sacrificed and thei

A comparison of lead lengths for mini-fyke nets to sample age-0 gar species
Mini-fyke nets are often used to sample small-bodied fishes in shallow (<1 m depth) water, especially in vegetated shoreline habitats where seines are ineffective. Recent interest in gar (Lepisosteidae) ecology and conservation led us to explore the use of mini-fyke nets to capture age-0 gar and specifically how capture is affected by lead length of the fyke net. In the summers of 2012, 2013, and

Ontogenetic development of otoliths in Alligator Gar
The Alligator Gar Atractosteus spatula is a species of conservation concern throughout its range, and better definition of otoliths during early development would aid understanding its life history and ecology. We conducted X-ray computed tomography scans, scanning electron microscopy, and light microscopy to examine the three pairs of otoliths and how they developed over time in relation to fish

Simulation modeling to explore the effects of length-based harvest regulations for Ictalurus fisheries
Management of Blue Catfish Ictalurus furcatus and Channel Catfish I. punctatus for trophy production has recently become more common. Typically, trophy management is attempted with length-based regulations that allow for the moderate harvest of small fish but restrict the harvest of larger fish. However, the specific regulations used vary considerably across populations, and no modeling efforts ha

Bait type influences on catch and bycatch in tandem hoop nets set in reservoirs
Tandem hoop nets have become the primary gear for sampling channel catfish Ictalurus punctatus, but suffer from high incidences of bycatch, particularly aquatic turtles that usually drown as a result. We sought to determine if bait type, ZOTE© soap and ground cheese logs, would influence catch of channel catfish (CPUE and mean TL) and bycatch of fishes and aquatic turtles. We sampled with tandem h

Measuring the relationship between sportfishing trip expenditures and anglers’ species preferences
We examined the relationship between fishing trip expenditures and anglers’ species preferences from a survey of Oklahoma resident anglers conducted in 2014. Understanding patterns in fishing trip expenditures is important because a significant share of state wildlife agency revenue comes from taxes on purchases of fishing equipment. Presently, there is little research that addresses the question

Early life history of three pelagic-spawning minnows Macrhybopsis spp. in the lower Missouri River
Life-history characteristics of age-0 sturgeon chub Macrhybopsis gelida, shoal chub Macrhybopsis hyostoma and sicklefin chub Macrhybopsis meeki were compared using several methods. AllMacrhybopsis species consumed mostly midge pupae, but M. meeki had the most general diet (Levins' index, B = 0·22) compared with M. hyostoma (B = 0·02) and M. gelida (B = 0·09). Morisita's diet overlap index among sp
