It was planned to sample monthly six fixed offshore stations at depths ranging from 5 to 50 fathoms in the open Gulf. In general this was carried out fairly well, as shown by Table 1. Water samples were taken from surface, midwater, and bottom levels each time a station was occupied, and temperatures and salinities were recorded for each of these. Samples were tested for the presence of nitrates, nitrites, ortho-phosphates and total phosphates. Secchi disc extinction points were recorded. Grab samples were taken for the determination of bottom composition. Plankton samples were taken from surface, midwater and bottom levels. Copepods, brachyuran zoea and megalops, stomatopod larvae, Lucifer faxoni, Acetes a. carolinae, Penilia avirostris, Doliolum sp. and fish eggs and larvae were present in greatest abundance. Surface and benthic nekton samples were obtained. Dredge samples were made quarterly and twelve invertebrate species and three species of fishes were collected. Renilla mulleri was the most abundant species taken, and the fish catch consisted of Centropristes ocyurus, Citharichthys spilopterus and Etropus crossotus. Accounts of 50 invertebrate species (24,679 specimens) and 129 fishes (93,563 specimens) taken in trawl hauls is presented. Tem- perature and salinity data are given for all species. Relative abundance, seasonal bathymetric distributions and movements, apparent growth patterns, catch per unit of effort and various biological data are noted for the most abundant species. Station 5 (40 fathoms) produced the largest percentage of trawl catches (22.7).Renilh mulleri was the most abundant invertebrate taken in trawling. The brown shrimp, Penaeus aztecus, was second in abundance (10.92%). The five most abundant species comprising 80.57% numerically of the catch were croaker, longspine porgy, butterfish, spot, and seatrout. The species comprising

The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described.

  • An Annotated Bibliography of Diet Studies of Fish of the Southeast United States and Gray’S Reef National Marine Sanctuary
    Marine Sanctuaries Conservation Series MSD-05-2 An annotated bibliography of diet studies of fish of the southeast United States and Gray’s Reef National Marine Sanctuary U.S. Department of Commerce February 2005 National Oceanic and Atmospheric Administration National Ocean Service Office of Ocean and Coastal Resource Management Marine Sanctuaries Division About the Marine Sanctuaries Conservation Series The National Oceanic and Atmospheric Administration’s Marine Sanctuary Division (MSD) administers the National Marine Sanctuary Program. Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program. Topics of published reports vary substantially and may include descriptions of educational programs, discussions on resource management issues, and results of scientific research and monitoring projects. The series facilitates integration of natural sciences, socioeconomic and cultural sciences, education, and policy development to accomplish the diverse needs of NOAA’s resource protection mandate.

  • South Carolina Department of Natural Resources
    FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas.

    A REVIEW OF THE SPARID^ AND RELATED FAMILIES OF PERCH-LIKE FISHES FOUND IN THE WATERS OF JAPAN. By David Starr Jordan and William Francis Thompson, Of Stanford University, California. In the present paper is given a review of the species of fishes belonging to those percomorphoiis famihes alUed to the Sparoid fishes, or fishes related to the tai or porgy of the waters of Japan, which have not been hitherto discussed in these pages by the senior author and his associates. The families of Kuldiidse, Priacanthidse, Theraponidse, Banjosidae, Hsemulidae, Sparidse, Kyphosidse, and Ery- thrichthyidse are thus included. The paper is based on material collected in Japan in 1900 by Pro- fessors Jordan and Snyder and now divided between the United States National Museum and the museum of Stanford University. Most of the cuts are from drawings by Mr. Sekko Shimada. The families here named are adopted provisionally only. The dis- tinctions between Sparidse, Haemulidse, Lutianidae, and their relatives are of doubtful value, while at present no definite boundaries can be assigned to the Serranidse. L Family KUHLIID.^. Body oblong, strongly compressed; scales large, cihated. Lateral line complete, the tubes straight and occupying the half or more of the exposed surface of the scale. Mouth rather large, protractile; maxillary exposed, without supplemental bone; teeth in jaws in villi- form bands; teeth on vomer, palatines, entopterygoids, and ecto- pterygoids; tongue smooth; head partly naked; preorbital and pre- opercle denticulate; opercle with 2 spines.

  • American Sole (Family Achiridae) Diversity in North Carolina
    American Sole (Family Achiridae) Diversity in North Carolina Along North Carolina’s shore there are three families of flatfish comprising five or six species having eyes on the right side of their body facing upward when lying in or atop the substrate (NCFishes.com; Tracy et al. 2020; Table 1; Figure 1). The families and species can be confusing to tell apart. The key characteristics provided in Table 1 should enable one to differentiate between the three families and this document will aid you in the identification of three species in the Family Achiridae (American Soles) in North Carolina. Generally, soles are small, flat, right-facing fishes (i.e., the left side of the body is on the substrate) with small, minute eyes and of little commercial or recreational value (Rohde et al. 2009). Table 1. The three families of right-facing flatfish found along and off the coast of North Carolina. Common Key Characteristics No. Family Name (adapted from Kells and Carpenter (2014); Munroe (2002a; 2002b)) Species • Preopercular margin not free, concealed by skin or represented only by a naked superficial groove. • Dorsal fin extending forward well in advance of eyes, the anterior rays concealed within a fleshy dermal envelope and difficult to see. Achiridae Soles • Lateral line essentially straight, without high arch over pectoral fin; often indistinct, but most readily seen on the eyed side, usually crossed at right angles by accessory branches (achirine lines) extending toward dorsal and anal fins; • Urinary papilla on eyed side. 2 or 3 • Preopercular margin free, not covered with skin and scales.

  • Age-Based Life History of the Mariana Islands' Deep-Water Snapper
    Age-Based Life History of the Mariana Islands’ Deep-Water Snapper, Pristipomoides filamentosus BY Francisco C. Villagomez A Thesis submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN BIOLOGY SUPERVISORY COMMITTEE Dr. Frank A. Camacho, Chair Dr. Kathleen A. Moots, Member Dr. Allen H. Andrews, Member UNIVERSITY OF GUAM NOVEMBER 2019 Abstract The deep-water snapper Pristipomoides filamentosus is a commercially important bottomfish in the Mariana Islands and is a significant component of annual bottomfish catches from the Marianas. However, life-history parameters that inform management of this species are poorly resolved and unvalidated for populations of P. filamentosus in the Mariana Islands. I investigated the life-history of P. filamentosus from the Mariana Islands, commonly known as opakapaka and buninas, and applied bomb-radiocarbon (14C) dating to validate traditional age estimates for this species. I determined the sex of male and female opakapaka histologically and used logistic regression analysis to investigate differences in length- and age-at-maturity between the sexes. The age of individual fish were estimated from counts of annuli from transverse sections of sagittal otoliths. I used a series of 14C-validated otoliths to corroborate visual estimates of age from otoliths collected from the Mariana Islands. The von Bertalanffy growth function was used to investigate the functional relationship of age and length between male and female opakapaka and to explore regional differences from the northern and southern Mariana Islands. I also investigated the utility of otolith mass and otolith thickness for predicting ages using regression analyses. Length and age at maturity for males and females were estimated at 29.3 cm FL at 2.8 years and 41.2 cm FL at 5.0 years, respectively.

DOWNEY BS, Texas A&M University–Corpus Christi, 2013 Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE in MARINE BIOLOGY Texas A&M University-Corpus Christi Corpus Christi, Texas December 2016 © Charles Hart Downey III All Rights Reserved December 2016 REPRODUCTION AND DIET OF RED SNAPPER LUTJANUS CAMPECHANUS ON NATURAL AND ARTIFICIAL REEFS IN THE NORTHWESTERN GULF OF MEXICO A Thesis by CHARLES H. DOWNEY This thesis meets the standards for scope and quality of Texas A&M University-Corpus Christi and is hereby approved. Gregory W. Stunz, PhD Matthew J. Ajemian, PhD Chair Committee Member Derek Hogan, PhD Committee Member December 2016 ABSTRACT Energy exploration in the Gulf of Mexico (Gulf) has resulted in the addition of numerous oil and gas production platforms adding structurally complex habitat to an area otherwise comprised of primarily barren mud/sand bottom. The impact of these artificial structures on fish populations is generally unknown, and there is ongoing debate regarding their performance in comparison to natural reefs. Thus, the purpose of this study was to characterize trends in Red Snapper reproduction and diet in the northwestern Gulf at oil and gas platforms relative to natural reefs. Red Snapper were collected from standing and reefed platforms and natural hard-bottom. Fecundity parameters (sex, total weight, gonad weight, total length) were measured, and these data showed Red Snapper fecundity and spawning behavior were similar among natural, standing, and reefed habitats.
