Lateral Muscle Development of the Pacific Bluefin Tuna, Thunnus Thynnus Orientalis, from Juvenile to Young Adult Stage Under Culture Condition
SUISANZOSHOKU 49(1), 23-28 (2001) Lateral Muscle Development of the Pacific Bluefin Tuna, Thunnus thynnus orientalis, from Juvenile to Young Adult Stage under Culture Condition Nobuhiro HATTom*1, Shigeru MIYASHITA*1, Yoshifumi SAWADA*2, Keitaro KATO*1, Toshiro NASU*1, Tokihiko OicADA*2, Osamu MURATA*1, and Hidemi KUMAI*1 (Accepted December 5, 2000) Abstract: The volume of lateral muscle, cross-sectional area of red and white fibers, and the number of fibers were examined for artificially hatched Bluefin tuna, Thunnus thynnus orientalis, from juvenile to young adult stage within the size range of 19.5-163.0 mm body length (BL). The red and white muscle volumes increased exponentially with BL. At a size larger than 80.0 mm BL, both the volume increases were significantly accelerated. The proportion of red muscle volume in the total lateral muscle volume slightly increased with BL. The cross-sectional area and the total num - ber of red and white fibers at the point of maximum body height increased in the BL range exam -ined. The small red fibers(<a100μm2 in size)of a cross-sectional area gradually disappeared with the growth of BL. In contrast, there existed the white small fibers(200-300μm2 in size)at all body sizes. Increases of both fiber numbers were approximately accelerated at sizes larger than 85 mm BL. The size of 80-85 mm BL, at which the phase change of muscle development occurred, corre -sponded to the transitional stage from juvenile to young adult. Key words: Thunnus thynnus orientalis; ontogenetic development; lateral muscle The seedstock production of the Pacific bluefin fish reach the body length (BL) of 80 to 160 tuna has developed remarkably in recent years mm. -

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. -

Bermuda's Marine Reserve
POTENTIAL IMPACTS OF BERMUDA’s MARINE RESERVE ON SPORTFISHING TOURISM The Need to Explore Other Options ECONOMIC RETURNS CAN FLOW TO COASTAL NATIONS that Implement Billfish Conservation Measures Sportfishing eco-tourism is a strong economic driver for communities. Visting anglers are driven by the likelihood of catching a lot of billfish. Anticipated quality of a billfishing trip greatly influences anglers’ destination choices. Anglers most often select fishing destination where commercial fishing is restrained. Responsible management of billfish can maximize catch rates and economic returns to communities.

Clean &Unclean Meats
Clean & Unclean Meats God expects all who desire to have a relationship with Him to live holy lives (Exodus 19:6; 1 Peter 1:15). The Bible says following God’s instructions regarding the meat we eat is one aspect of living a holy life (Leviticus 11:44-47). Modern research indicates that there are health benets to eating only the meat of animals approved by God and avoiding those He labels as unclean. Here is a summation of the clean (acceptable to eat) and unclean (not acceptable to eat) animals found in Leviticus 11 and Deuteronomy 14.
