On the Biology of Florida East Coast Atlantic Sailfisht' Íe (Istiophorus Platypterus)1
SJf..... z e e w e t e k r " - Ka,; ,y, -, V öi'*DzBZöm 8429 =*==,_ r^ä r.-,-. On the Biology of Florida East Coast Atlantic SailfishT' íe (Istiophorus platypterus)1 JOHN W. JOLLEY, JR .2 149299 ABSTRACT The sailfish, Istiophorus platypterus, is one of the most important species in southeast Florida’s marine sport fishery. Recently, the concern of Palm Beach anglers about apparent declines in numbers of sailfish caught annually prompted the Florida Department of Natural Resources Marine Research Laboratory to investigate the biological status of Florida’s east coast sailfish populations. Fresh specimens from local sport catches were examined monthly during May 1970 through September 1971. Monthly plankton and “ night-light” collections of larval and juvenile stages were also obtained. Attempts are being made to estimate sailfish age using concentric rings in dorsal fin spines. If successful, growth rates will be determined for each sex and age of initial maturity described. Females were found to be consistently larger than males and more numerous during winter. A significant difference in length-weight relationship was also noted between sexes. Fecundity estimates varied from 0.8 to 1.6 million “ ripe” ova, indicating that previous estimates (2.5 to 4.7 million ova) were probably high. Larval istiophorids collected from April through October coincided with the prominence of “ ripe” females in the sport catch. Microscopic examination of ovarian tissue and inspection of “ ripe” ovaries suggest multiple spawning. Florida’s marine sport fishery has been valued as a in 1948 at the request of the Florida Board of Con $200 million business (de Sylva, 1969). -

Frequently Asked Questions
atlaFrequentlyntic white Asked mQuestionsarlin 2007 Status Review WHAT ARE ATLANTIC WHITE MARLIN? White marlin are billfish of the Family Istiophoridae, which includes striped, blue, and black marlin; several species of spearfish; and sailfish. White marlin inhabit the tropical and temperate waters of the Atlantic Ocean and adjacent seas. They generally eat other fish (e.g., jacks, mackerels, mahi-mahi), but will feed on squid and other prey items. White marlin grow quickly and can reach an age of at least 18 years, based on tag recapture data (SCRS, 2004). Adult white marlin can grow to over 9 feet (2.8 meters) and can weigh up to 184 lb (82 kg). WHY ARE ATLANTIC WHITE MARLIN IMPORTANT? Atlantic white marlin are apex predators that feed at the top of the food chain. Recreational fishers seek Atlantic blue marlin, white marlin, and sailfish as highly-prized species in the United States, Venezuela, Bahamas, Brazil, and many countries in the Caribbean Sea and west coast of Africa. White marlin, along with other billfish and tunas, are managed internationally by member nations of the International Commission for the Conservation of Atlantic Tunas (ICCAT). In the United States, Atlantic blue marlin, white marlin, and Atlantic sailfish can be landed only by recreational fishermen fishing from either private vessels or charterboats. WHAT IS A STATUS REVIEW? A status review is the process of evaluating the best available scientific and commercial information on the biological status of a species and the threats it is facing to support a decision whether or not to list a species under the ESA or to change its listing. -

The most suitable methods for processing and inter- preting these calcified structures for age estimation have not been clearly defined. Methodological differences between unvalidated ageing studies are of particular concern for highly migratory species because multiple researchers in dif- ferent regions of the world may conduct age estimates on the same species or stock. This review provides a critical overview of the methods used in previous fin spine ageing studies on billfishes and provides recommendations towards the development of a standardized protocol for estimating the age of striped marlin, Kajikia audax and white marlin, Ka- jikia albida. Three on-going fin spine ageing studies from Australia, Hawaii, and Florida are used to illustrate some of the considerations and difficulties encountered when developing an ageing protocol for highly migratory fish species. -

A Contribution to the Life History and Biology of the Sailfish, <I
A CONTRIBUTION TO THE LIFE HISTORY AND BIOLOGY OF THE SAILFISH, ISTIOPHORUS AMERICANUS CUV. AND VAL., IN FLORIDA WATERS' GILBERT L. VOSS The Marine Laboratory, University of Miami ABSTRACT Thirteen specimens of post-larval and juvenile stages of the Western Atlantic sailfish, Istiophorus american us, are described, ranging in standard length from 3.9 mm to 208.0 mm, and ten specimens are illustrated, all from the Florida Current. These are compared with previously published descriptions and illustrations of young Istiophoridae. The developmental changes from post-larval to adult are described and the general biology is discussed. Florida populations of sailfish spawn during the early summer near shore and no migrations are observable in Florida waters. The food and methods of feeding are described and the results of tagging operations are given. INTRODUCTION The present study is part of the results obtained from a continuing study of the life histories and biology of Florida fishes, especially the food and game fish, supported by the National Geographic Society and the Florida State Board of Conservation, and carried out by the Marine Laboratory of the University of Miami. In 1948 the Marine Laboratory, at the request of the Florida State Board of Conservation, initiated a study of the biology. of the sailfish in Florida waters in an attempt to solve certain conservation problems relating to this important gamefish. This study was set in progress by the present writer who carried it through for a period of one and a half years. From that period to date the program has been carried out by Melvin Light, Winfield Brady, and H. -
