James M. Long, PhD
Unit Leader - Oklahoma Cooperative Fish and Wildlife Research Unit
Dr. Long 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, Dr. Long worked with the National Park Service as the Fishery Biologist for the southeast region. In 2009, Dr. Long moved back to Oklahoma as an Assistant Unit Leader and become Unit Leader in 2016. Dr. Long'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, Dr. Long has been particularly engaged in issues related to black bass diversity, highlighting the conservation needs of these endemic and iconic species. Dr. Long uses Geographic Information Systems (GIS) and side-scan sonar technology to address research needs in a wide variety of aquatic ecosystems. Dr. Long is also actively engaged in applying novel tools to better understand otolith morphology and composition to elucidate age, growth, and development in fishes. Dr. Long teaches a graduate level course in Social Dimensions in Aquatic Ecology.

Age-0 Shovelnose Sturgeon prey consumption in the Lower Missouri River
A lack of nutritious food during the first year of life is a hypothesized factor that may limit survival of endangered pallid sturgeonScaphirhynchus albus in the lower Missouri River (LMOR). Unfortunately, information for age-0 pallid sturgeon diets remains limited, but diet analyses for age-0 Scaphirhynchus spp. (sturgeon hereafter) have occurred. Little information, however, exists on age-0 sturAuthorsN.J.C. Gosch, M.L. Miller, T. R. Gemeinhardt, Trevor A. Starks, A. P. Civiello, James M. Long, J. L. BonneauEffects of a growth check on daily age estimates of age-0 alligator gar
Accurate age and growth information is essential for a complete knowledge of life history, growth rates, age at sexual maturity, and average life span in fishes. Alligator gar are becoming increasingly managed throughout their range and because this species spawns in backwater flooded areas, their offspring are prone to stranding in areas with limited prey, potentially affecting their growth. BecaAuthorsRichard A. Snow, James M. LongIdentification of Neosho Smallmouth Bass (Micropterus dolomieu velox) stocks for possible introduction into Grand Lake, Oklahoma
Stocking black basses (Micropterus spp.) is a common practice used to increase angling opportunities in impoundments; however, when non-native black basses are introduced they often invade riverine habitats where they threaten the persistence of other fishes, including native black basses. Neosho Smallmouth Bass (M. dolomieu velox) is endemic to portions of the Ozark Highlands and Boston MountainsAuthorsAndrew T. Taylor, James M. Long, Michael R. Schwemm, Michael D. Tringali, Shannon K. BrewerAssessing the potential for rainbow trout reproduction in tributaries of the Mountain Fork River below Broken Bow Dam, southeastern Oklahoma
Stocked trout (Salmonidae) in reservoir tailwater systems in the Southern United States have been shown to use tributary streams for spawning and rearing. The lower Mountain Fork of the Little River below Broken Bow Dam is one of two year-round tailwater trout fisheries in Oklahoma, and the only one with evidence of reproduction by stocked rainbow trout (Oncorhynchus mykiss). Whether stocked troutAuthorsJames M. Long, Trevor A. Starks, Tyler Farling, Robert BastaracheBiology and ecology of Neosho Smallmouth Bass and the genetically distinct Ouachita lineage
We reviewed the published and gray literature associated with Neosho Smallmouth Bass and the genetically-distinct Ouachita lineage. Substantial inter-stream variation appears to occur among these populations, particularly related to age. The Neosho subspecies is more abundant, grows faster, and lives longer than the genetically-distinct Ouachita lineage. Recruitment is highly variable among streamAuthorsShannon K. Brewer, James M. LongClimate, water use, and land surface transformation in an irrigation intensive watershed - streamflow responses from 1950 through 2010
Climatic variability and land surface change have a wide range of effects on streamflow and are often difficult to separate. We analyzed long-term records of climate, land use and land cover, and re-constructed the water budget based on precipitation, groundwater levels, and water use from 1950 through 2010 in the Cimarron–Skeleton watershed and a portion of the Cimarron–Eagle Chief watershed in OAuthorsJoseph Dale, Chris B. Zou, William J. Andrews, James M. Long, Ye Liang, Lei QiaoGrowth and contribution of stocked channel catfish, Ictalurus punctatus (Rafinesque, 1818): the importance of measuring post-stocking performance
In this study it was sought to quantify post-stocking growth, survival, and contribution of advanced size (178 mm total length [TL]) channel catfish Ictalurus punctatus fingerlings, something rarely done. Channel catfish populations were evaluated before (May 2010) and after (May to August 2011 and 2012) stocking.

Shoal bass are native only to the Apalachicola-Chattahoochee-Flint river system of Georgia, Alabama, and Florida, and are vulnerable to extinction as a result of population fragmentation and introduction of non-native species. We assessed the genetic integrity of isolated populations of shoal bass in the upper Chattahoochee River basin (above Lake Lanier, Big Creek, and below Morgan Falls Dam) andAuthorsElizabeth E Dakin, Brady A. Porter, Byron J. Freeman, James M. LongCommunity structure of age-0 fishes in paired mainstem and created shallow-water habitats in the Lower Missouri River
Anthropogenic alterations to aquatic ecosystems have greatly reduced and homogenized riverine habitat, especially those used by larval and juvenile fishes. Creation of shallow-water habitats is used as a restoration technique in response to altered conditions in several studies globally, but only recently in the USA. In the summer of 2012, the U.S. Army Corps of Engineers sampled larval and juveniAuthorsTrevor A. Starks, James M. Long, Andrew R.

We used an experimental manipulation to determine the impact of stocking 178 mm channel catfish Ictalurus punctatus in six impoundments. The study design consisted of equal numbers (two) of control, ceased-stock, and stocked treatments that were sampled one year before and two years after stocking.
