<I>Pristipomoides</I> A NEW SPECIES OF PRISTIPOMOIDES (PISCES: LUTJANIDAE) FROM THE TROPICAL WESTERN ATLANTIC1 WILLIAM D. ANDERSON, JR.::! U. S. Bureau of Commercial Fisheries Biological Laboratory, Brunswick, Georgia ABSTRACT A new species of lutjanid fish of the genus Pristipomoides is described from 28 specimens collected off Panama, Colombia, and Surinam in 137 to 183 m and one from the fish market at Bridgetown, Barbados. Brief descriptions, and discussions of synonymies and distributions of the other two western Atlantic species of the genus (Pristipomoides aquilonaris and P. macrophthalmus) are given; a key to the three species is presented. INTRODUCTION Twenty-eight specimens of a new species of Pristipomoides were collected in the western Atlantic off Panama, Colombia, and Surinam during cruises of the U. S. Bureau of Commercial Fisheries exploratory fishing vessel OREGON.An additional specimen was obtained from the fish market at Bridgetown, Barbados. Many specimens of the other two western Atlantic species of Pristipomoides, P. aquilonaris (Goode & Bean, 1896), and P. macroph- thalmus (MUller & Troschel, 1848), have been collected aboard the R/V SILVERBAY (formerly chartered by the U. S. Bureau of Commercial Fisheries) and the R/V OREGON.From this material we can derive new concepts of the biology and zoogeography of these two species. Other species of Pristipomoides have been recorded from the central Pacific to the Indian Ocean. Altogether there are approximately 10 nominal species of Pristipomoides.

Berry (TABL), Jack W. Gehringer (BLBG), Carter R. Gilbert (UF), John E. Randall (UPR), and Loren P. Woods (CNHM) read the manuscript and made valuable comments. METHODS Counts and measurements were made according to the methods outlined by Hubbs & Lagler (1958), except body depth was measured from the origin of the first dorsal spine vertically to the ventral surface of the body. 816 Bulletin of Marine Science [16 (4) On specimens in which the two pectoral fins and two pelvic fins were of unequal length, the longer fin was measured. Pectoral-fin rays and lateral-line scales were counted on the left side of specimens, where possible. All gillraker counts were made from the right side of the new species and in P. macrophthalmus, and from the right side, where possible, in P. aquilonaris. Both well-developed rakers and rudiments on the antero- lateral surface of the anterior gill arch were included in the gillraker counts. In some specimens of Pristipomoides aquilonaris and P. macroph- thalmus, "intercalated" gillrakers and rudiments may be present between, lateral to, or medial to those in the anterolateral series. These "inter- calated" elements were not counted. Counts shown in parentheses were encountered infrequently.

Snapper and grouper are important fishery resources with great commercial value for exporters to major international markets. The fisheries also support the livelihoods and food security of many local, small-scale fishing communities worldwide. It is therefore all the more critical that management of these fisheries improves, thus ensuring this important resource will remain available to provide both food and income. Landings of snapper and grouper have been steadily increasing: in the 1950s, total landings were about 50,000 tonnes, but they had grown to more than 612,000 tonnes by 2013.

    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.

  • 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 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.

  • Bluestriped Grunt (Haemulon Sciurus) in Bermuda: Age, Growth, and Reproduction Studies
    Bluestriped Grunt (Haemulon sciurus) in Bermuda: Age, Growth, and Reproduction Studies JOANNA M. PITT1, TAMMY M. TROTT1 , and BRIAN E. LUCKHURST1, 2 1Marine Resources Division, P.O. Box CR52, Crawl CRBX, Bermuda 2Current address: 2-4 Via della Chiesa, 05020 Acqualoreto, Umbria, Italy ABSTRACT Samples of Bluestriped Grunt (Haemulon sciurus) from Bermuda, primarily obtained between 2001 and 2008 while investigating a potential spawning aggregation, were analysed for age, growth and reproductive characteristics. Individuals were aged from 2 to 23 years and ranged in size from 18.2 to 35.1 cm fork length (FL). Size-at-age was highly variable, with size ranges spanning up to 6 cm for a given year class, and this was reflected in otolith weights. Therefore, otolith weight is not a good proxy for age in this species. The 3+ year class was the first class of mature individuals that was abundant in the samples collected from the aggregation site, and 4- and 5-year old fish were more abundant than 3-year old fish. This suggests that the average age of first reproduction for Bluestriped Grunt in Bermuda is 3 to 4 years. Average size of 3+ fish was 25.4 cm, and maximum size was 28.4 cm. Average and maximum sizes of 4+ fish were 26.3 cm and 30.4 cm respectively. Based on these data, a minimum legal size for retention of captured Bluestriped Grunts in Bermuda may be set at 28 cm / 11” FL. The maximum weight recorded from these samples was 821 g, and the length-weight relationship derived from these data is W = 0.0126 × L3.1315, where W = whole weight (g) and L = fork length (cm).
