BARBIERI AND JAMES A. COLVOCORESSES PREPARATION DATE: JUNE 2003 - PREFACE SOUTHEAST FLORIDA REEF FISH ABUNDANCE AND BIOLOGY This is an interim report on the first five years of an ongoing study of the biology, life history, and population dynamics of important reef fish in southeast Florida. This first phase of the grant included studies that focused on yellowtail snapper (Ocyurus chrysurus), gray snapper (Lutjanus griseus), mutton snapper (L. analis) and lane snapper (L. synagris), all of which support important recreational (as well as commercial) reef fisheries in Florida. Studies on other species will be initiated in the future as additional species important to recreational reef fisheries in Florida are identified. Results presented in this report include manuscripts that have already been published as well as unpublished reports that address various project components (i.e., age and growth, reproduction, feeding habits, etc.). This report is organized in three main Sections: Section I includes the preliminary results of the study on age, growth, and reproduction of the four targeted snappers species listed above. Section II includes two separate studies on the feeding ecology of these same snapper species. Section III presents the results of the artificial reef monitoring program conducted in cooperation with Palm Beach County’s Department of Environmental Resources Management. This work was supported in part under funding from the Department of the Interior, U.S. Fish and Wildlife Service, Federal Aid for Sport Fish Restoration Grant Number F-73. - 1 - - TABLE OF CONTENTS SECTION I – LIFE HISTORY........................................................................................... 4 Age, Growth, and Reproduction of Snappers in Southeast Florida............................ 4 Introduction............................................................................................................. 4 Methods................................................................................................................... 5 Study Area .................................................................................................. 5 Collection Methods................................................................................... 10 Laboratory Processing .............................................................................. 15 Otolith Removal and Storage.................................................................... 17 Otolith Sectioning and Mounting.............................................................. 17 Age Assignment........................................................................................ 19 Age Validation.......................................................................................... 21 Aging Precision......................................................................................... 21 Length and Weight Relationships............................................................. 21 Growth Estimates...................................................................................... 22 Mortality Estimates................................................................................... 22 Results................................................................................................................... 23 Numbers and Sizes of Fish Sampled ........................................................ 23 Age Determination.................................................................................... 28 Growth ...................................................................................................... 28 Maturity and Spawning............................................................................. 50 Literature Cited ..................................................................................................... 50 SECTION II – FEEDING ECOLOGY............................................................................. 62 Feeding Ecology of Four Species of Snappers ........................................................ 62 Introduction........................................................................................................... 62 Objectives ............................................................................................................. 63 Methods................................................................................................................. 63 Chevron traps............................................................................................ 63 Hook-and-line gears.................................................................................. 64 -

This fish community consists of demersal tropical and subtropical species which generally occupy true coral reefs as well as “live-bottom” habitats and are caught by common fishing methods on continental shelf waters. Although the 1983 South Atlantic Fishery Management Council’s snapper-grouper fishery management plan includes a total of 8 families, snappers (family Lutjanidae) and groupers (family Serranidae) are the most important in terms of number of species, desirability as food and sport fishes as well as in magnitude of catches.

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.

Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices”, “Good Alternatives” or “Avoid.” The detailed evaluation methodology is available upon request.

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous.

    Lane Snapper (Lutjanus Synagris)

    Tab B, No. 8(b) 2/18/2020 Lane Snapper (Lutjanus synagris) Description: Lane snapper is a member of the snapper family (Lutjanidae). It is typically almond-shaped, colored pink- red around the edges with a silvery body color, and has a number of pink and yellow lines running along the body from head to tail. It often has a distinctive spot on its upper side and can be easily confused with mutton snapper. The Gulf of Mexico stock is distinct from the Atlantic. Lane snapper occurs in a variety of habitats such a reefs and inshore sandy bottom vegetated habitats. Lane snapper are experiencing overfishing (2019) but its stock status is Photo credit: Dylan Hubbard unknown (SEDAR 49 2016). Gulf Stock Characteristics: (SEDAR 49 2016) Natural mortality rate (M): 0.33/year (max. age of 19 years) Reproductive maturity: 50% of females are mature at ~9 inches (24.0 cm) fork length (FL); ~age 1-2 Maximum age: 19 years Maximum weight: 13 lbs (5.9 kg) whole weight Maximum length: 18 inches (44.9 cm) FL Discard mortality: 5-15% (fleet dependent) Life History and Distribution: (SEDAR 49 2016) Lane snapper is distributed from the North Atlantic off North Carolina through the Gulf of Mexico and Caribbean to Southern Brazil. It generally feeds at night and preys upon a variety of species such as smaller fish, shrimp, and crabs. Peak spawning occurs along shelf habitats from June through August. Larvae settle around 21-66 days on near-shore shell ridge habitats as well as muddy habitats. Adults often occur in high- relief offshore habitats in water depths up to 430 feet (~132 meters) and in areas with high salinity (>30 psu) with variable water temperatures (16-29 ̊C).
