    A Black Marlin, Makaira Indica, from the Early Pleistocene of the Philippines and the Zoogeography of Istiophorid B1llfishes

    BULLETIN OF MARINE SCIENCE, 33(3): 718-728,1983 A BLACK MARLIN, MAKAIRA INDICA, FROM THE EARLY PLEISTOCENE OF THE PHILIPPINES AND THE ZOOGEOGRAPHY OF ISTIOPHORID B1LLFISHES Harry L Fierstine and Bruce 1. Welton ABSTRACT A nearly complete articulated head (including pectoral and pelvic girdles and fins) was collected from an Early Pleistocene, upper bathyal, volcanic ash deposit on Tambac Island, Northwest Central Luzon, Philippines. The specimen was positively identified because of its general resemblance to other large marlins and by its rigid pectoral fin, a characteristic feature of the black marlin. This is the first fossil billfish described from Asia and the first living species of billfi sh positively identified in the fossil record. The geographic distribution of the two living species of Makaira is discussed, Except for fossil localities bordering the Mediterranean Sea, the distribution offossil post-Oligocene istiophorids roughly corresponds to the distribution of living adult forms. During June 1980, we (Fierstine and Welton, in press) collected a large fossil billfish discovered on the property of Pacific Farms, Inc., Tambac Island, near the barrio of Zaragoza, Bolinao Peninsula, Pangasinan Province, Northwest Cen­ tral Luzon, Philippines (Fig. 1). In addition, associated fossils were collected and local geological outcrops were mapped. The fieldwork continued throughout the month and all specimens were brought to the Natural History Museum of the Los Angeles County for curation, preparation, and distribution to specialists for study. The fieldwork was important because no fossil bony fish had ever been reported from the Philippines (Hashimoto, 1969), fossil billfishes have never been described from Asia (Fierstine and Applegate, 1974), a living species of billfish has never been positively identified in the fossil record (Fierstine, 1978), and no collection of marine macrofossils has ever been made under strict stratigraphic control in the Bolinao area, if not in the entire Philippines.

    Section IV – Guideline for the Texas Priority Species List

    Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

We sampled the dorsal white muscle of 47 M. nigricans and 35 K. audax collected from 2005 to 2007. No relationship was found between billfish body size and isotopic values. Significant differences in15 δ N and δ13C values were found among genders, years, or areas for K. audax. The significant differences in15 δ N and δ13C values found between areas for M. nigricans suggested differences in foraging preferences or movement patterns. Significant differences were also found in15 δ N and δ13C values between K. audax and M. nigricans, possibly placing these two billfish species at different trophic levels. These patterns appear to correspond to each species’ known foraging ecology and suggest that these two billfishes have different trophic preferences or migratory histories. Billfishes are pelagic fishes of great economic importance for both sport and com- mercial fisheries (Nakamura 1985). These highly migratory species, including striped marlin, Kajikia audax (see Appendix 1 for species authorities), and blue marlin, Makaira nigricans, are a major recreational fishing resource in the southern Gulf of California (González-Armas et al.

    BULLETIN OF MARINE SCIENCE. 88(2):231–250. 2012 http://dx.doi.org/10.5343/bms.2011.1025 SEXUAL DIFFERENCE IN THE MIGRATION PATTERN OF BLUE MARLIN, MAKAIRA NIGRICANS, RELATED TO SPAWNING AND FEEDING ACTIVITIES IN THE WESTERN AND CENTRAL NORTH PACIFIC OCEAN Tamaki Shimose, Kotaro Yokawa, Hirokazu Saito, and Katsunori Tachihara ABSTRACT The reproductive condition and stomach contents of blue marlin, Makaira nigricans Lacépède, 1802 (n = 645), were quantitatively investigated in three different regions of the North Pacific Ocean between 2003 and 2009. Males strongly dominated (females:males = 34:439) in Region III (4°N–21°N, 131°E–154°W) throughout the year, and eight females (28%) had ovaries in the maturing or spawning stage. Although the sampling months were limited to September– November in Region II (18°N–32°N, 171°W–140°W), the sex ratio was more similar (females:males = 28:26) and there was no evidence of spawning. Only females (n = 100) were observed in Region I (33°N–36°N, 135°E–140°E) from July to September, the main season when blue marlin occur off the coast of Japan, and no females had ovaries in the maturing or spawning stage. Stomach-content analysis revealed that the feeding intensity of females was higher in Region I than in the other two regions. These results suggest that blue marlin prey items may be more abundant at non- spawning areas in Region I, to which female blue marlin migrate for feeding. In contrast, lower feeding intensities and evidence of spawning in Region III suggest that blue marlin prey may be scarce in spawning areas.

    Blue Marlin in the Gulf of Mexico: the Facts

    Blue Marlin in the Gulf of Mexico: the facts The Atlantic blue marlin (Makaira nigricans), one of the largest billfish species in the world, presents a formidable challenge to recreational fishermen. Many anglers consider catching a blue marlin to be the pinnacle of angling success. The International Game Fish Association’s all-tackle record for this species is 1,402 pounds. The fish has brilliant colors, with bright cobalt blue on top, a silver-white belly and a series of colorful vertical stripes along the length of its body. Females can live more than 30 years, while males generally live no more than 18.1 A blue marlin weighing more than 350 pounds is probably female; males are smaller.2 These fish are long-lived.

A stock assessment based on JABBA was conducted in 2018 for black marlin. This assessment suggests that the point estimate for the stock in 2017 is in the green zone in the Kobe plot with F/FMSY=0.96 (0.77-1.12) and B/BMSY=1.68 (1.32-2.10). The Kobe plot (Fig. 2) from the JABBA model indicated that the stock is not subject to overfishing and is currently not overfished (Table 1; Fig. 2), however these status estimates are subject to a high degree of uncertainty.
