OLDFIELD1,2, ABHINAV KAKUTURU1, WILLIAM I. LUTTERSCHMIDT2, O. TOM LORENZ3, ADAM E. COHEN4, AND DEAN A. HENDRICKSON4 ABSTRACT The Rio Grande Cichlid, Herichthys cyanoguttatus, is native to the drainages of the Gulf Coast of northern Mexico and southern Texas and has been introduced at several sites in the US. Previous observations have suggested that non-native populations in Louisiana that are currently recognized as H. cyanoguttatus resemble another species, the Lowland Cichlid, H. carpintis. Traditional morphological and genetic techniques have been insufficient to differentiate these species, but H. carpintis has been reported to differ fromH. cyanoguttatus in color pattern, so we turned to novel electronic photo archives to determine the identity of the species introduced in Louisiana. First, we used the public databases Nonindigenous Aquatic Species Database and Fishes of Texas to infer the historical distributions of these species in the US. -
B. Quantitative Characters Morphometric & Meristics Laboratory
Lab. No. 2 B. Quantitative Characters Morphometric & Meristics laboratory Taxonomic Characters The first step in successfully working with fishes is correct identification. Similar species require in depth examination to discern the few differentiating characteristics. Many times these examinations require accurate measurements and counts of fin ray elements. Objectives: The purpose of this lab is to introduce students to these characters. Quantitative Characters Quantitative characters are usually expressed as numbers, these include a measurable and countable characters. Morphometrics are measurable characters or length-based measures of specific body parts, such as total length of the body or diameter of the eye. These characters are usually measured in the millimeter scale. Meristics are counts of things which occur more than once, but a variable number of times between species (and sometimes within species). These include counts of fin elements, i.e.: the number of dorsal fin spines and rays. NOTICE Spines are hard, pinlike projections, while rays are soft and brush-like Occasionally, fins will be a mix of both spines and rays; however, spines are ALWAYS the most forward structures (closest to the head) on the fin. The table below helps you to differentiate between a spine and a ray Spines Rays Hard and pointed Segmented Unsegmented Sometimes branched Unbranched Bilateral with left and right halves Solid Because they are already dimensionless, meristic measurements can be compared directly. 8 Lab. No. 2 Laboratory exercise In this exercise we will be making various measurements and counts on several species of fish. Record the appropriate information in the attached table. Procedure—Morphology • Each group is equipped with: • Dissecting microscope • Needle probe • Dissecting tray • Scissors • Petri dish • Scalpel • Calipers • Slides and coverslips • Forceps (fine tip and blunt tip) • Latex gloves (optional) Each team should get a fish. -

Understanding the genetic basis of phenotypic variation in body form could lead to breeding strategies aimed at adapting body shape to captive environments. In the present study, QTLs associated with morphometric and meristic traits in rainbow trout were identified using a genetic linkage map created from a cross of two clonal lines divergent for morphology and life history (wild steelhead trout and domesticated rainbow trout). Genome regions associated with differences in morphological (body depth, mouth orientation, caudal peduncle shape, anal and dorsal fin length) and meristic (number of skeletal elements of median and paired fins and of caudal fin) characters were identified. The identification of genomic locations influencing body morphology, even if only at a gross level, could be of pivotal importance to direct breeding strategies in commercial hatcheries towards the production of more desirable body types. -
Peoria Riverfront Development, Illinois (Ecosystem Restoration)

BOX 2004 ROCK ISLAND, ILLINOIS 61204-2004 REPLY TO ATTENTION OF http://www.mvr.usace.army.mil CEMVR-PM-M PEORIA RIVERFRONT DEVELOPMENT, ILLINOIS (ECOSYSTEM RESTORATION) FEASIBILITY STUDY WITH INTEGRATED ENVIRONMENTAL ASSESSMENT MAIN REPORT MARCH 2003 Executive Summary he Peoria Riverfront Development (Ecosystem Restoration) Project area includes Lower Peoria Lake. The area lies within Peoria and Tazewell Counties, Illinois, and includes TIllinois River Miles 162-167. The project is related to the Peoria Riverfront Development Project, a public and private cooperative effort that also includes revitalization of the City’s downtown area. Development includes a visitor’s center, city park, residential redevelopment, community center, riverboat landing, sports complex, entertainment centers, and retail development. The region has begun to reclaim its abandoned industrial riverfront, with the understanding that a healthy, attractive, and sustainable environment must be present. The Illinois River is a symbol of the region’s economic, social, and cultural history, as well as its future. Therefore, ecosystem restoration in Peoria Lake is a vital component to an overall effort and vision to develop the Peoria Riverfront in an ecologically, economically, and socially sustainable manner. This Ecosystem Restoration Feasibility Study was conducted by the U.S. Army Corps of Engineers and the Illinois Department of Natural Resources (Non-Federal Sponsor) to investigate the Federal and State interest in ecosystem restoration within Peoria Lake. In support of this resource vision, several regulatory efforts on the part of the cities and counties to address the sedimentation issue affecting the Illinois River have been adopted. -

SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips. -

Here we investigate other morphometric and meristic characters that can also be used to differentiate these two species. Principal component and/or discriminant functions revealed that meristic characters were highly correlated with pectoral fin ray count, number of lateral line scales, as well as number of anal fin rays. The results indicate that T. chatareus can be distin- guished from T. -

GREEN SUNFISH (Lepomis Cyanellus)
GREEN SUNFISH Oneida Lake Status: (Lepomis cyanellus) Not Common • Oneida Lake population small but on the rise • Out competes bluegills in Oneida Lake • Hybridization makes identification difficult Green sunfish may grow to 9 inches in Oneida Lake, and weigh up to a ½ pound. Green sunfish are not as deep bodied as other commonly known sunfish, and typically have a more Green sunfish in the wild: drab color scheme. They have a blue-green back that fades to http://www.bobberstop.com/images/gr yellow or white at the belly, and have a black earflap with a een_sunfish.jpg yellow edge (see drawing). Green sunfish have a top jaw that extends back to the middle of the eye, and a mouth that is larger than its close relatives. Unfortunately, green sunfish may hybridize with pumpkinseed and bluegill sunfish (see photo to left), making identification difficult. Sunfish identification becomes difficult when hybridization occurs: http://www.southernpondsandwildlife.c om/upload/articletitles/000052.50.jpg Small green sunfish before release back to the water: http://www.tnfish.org/PhotoGalleryFish_TWRA/FishPhotoGallery_ TWRA/pages/GreenSunfishMeltonHillNegus_jpg.htm Green sunfish do not favor any bottom type in Oneida Lake, but generally live near brush, vegetation, and rocks. Unlike most sunfish, greens tolerate areas with high turbidity and Line drawing of a green sunfish low dissolved oxygen. In Oneida, green sunfish eat small fish, aquatic insects, and other invertebrates, and their large mouths allow them to eat larger prey than other sunfish can. Prepared by: Green sunfish are found in Oneida Lake and throughout New York State. While it is possible that they are native to Alexander Sonneborn Oneida, green sunfish are an invasive exotic in many places Cornell Biological Field Station and often out-compete the native bluegill.
