Between December 14, 2006, and November 18, 2010, eight reef fish sample collection events funded by FWC were completed resulting in a total of 315 legal size reef fish retained for skin-on congener-specific analysis of 209 PCB congeners (254 fish from the Oriskany Reef, and 61 fish from the nearby Pensacola Bay Fishing Bridge Reef). The 254 retained reef fish from the Oriskany Reef included: 184 red snapper, 42 vermilion snapper, 14 red porgy, 6 whitebone porgy, 4 scamp grouper, 2 gray triggerfish, and 1 red grouper. Initially the mean PCB level for fish samples from the Oriskany Reef collected within the first two years post-deployment (sample rounds 1-4) had combined mean total PCB values exceeding the Florida Department of Health (FDOH) screening value of 50 ppb and the EPA screening value of 20 ppb. By sample round 5, collected at 2.9 years, the mean PCB level measured decreased to below the FDOH value and slightly above the EPA value. By sample round 6 and 7, collected at 3.5 and 3.9 years, the mean PCB levels were below both the FDOH and EPA thresholds. Sample round 8 samples (n=39), collected at 4.5 years are currently being processed and are expected by June 2011. Sample round 9 is scheduled for April 26, 2011 (4.9 years post- deployment). The species with the highest PCB levels observed included red snapper (n=172), red porgy (n=7), and whitebone porgy (n=4). No samples of vermillion snapper (n=28) or scamp (n=1) exceeded the FDOH or EPA thresholds. Overall, these results indicate a declining trend during the last 2 years of sampling. Additionally, 10 underwater visual assessments were conducted on the Oriskany Reef by FWC divers, confirming the observed recreationally targeted species found on the Oriskany are well represented among the fish retained for PCB analysis. Visual observations by FWC divers also documented that the Oriskany Reef had settled into the sediments about 10 ft at 2.5 years post deployment and sustained minor structural change to the exterior covering of the smoke stack at 3.5 years post deployment following the tropical storm events of 2007 and 2008, respectively. Results from 199 fish tagged and released on the Oriskany reef provide preliminary reef fish site fidelity and considerations of localized fishing effort. Review of the results of other FWC funded reef fish research projects in the vicinity are discussed as they relate to the fish species sampled on the Oriskany Reef. Options for consideration of future sample collection efforts at the Oriskany Reef through the end of 2011 are provided. 3 | Page LIST OF TABLES Table Page No. 1.

With 1,357 miles of coastline, involvement by 34 different counties, and over 2,500 artificial reefs deployed to date, Florida manages one of the most diverse and most active artificial reef programs in the United States. Because artificial reef development in Florida works with, and depends upon, a network of local partners, inter-county coordina- tion and communication is critical to ensure successful implementation of statewide strate- gic objectives for artificial reef development. This Summit occurs every 3 to 5 years and provides the format for local partners to meet and exchange information. It is a critical opportunity for the Florida Fish and Wildlife Con- In Memoriam servation Commission Artificial Reef Program and Florida Sea Grant to disperse high-quality information, experience and program goals and objectives directly with all of Florida’s The 2010 Artificial Reef Summit is dedicated to the memory of Chris Koepfer, the long-time Lee County Arti- artificial reef stakeholders. ficial Reef Coordinator who passed away in 2009.

Characterization of commercial reef fish catch and bycatch off the southeast coast of the United States. Patrick J. Harris, South Carolina Department of Natural Resources, Charleston, SC 29412. Grant Number: NA03NMF4540416 July 2005. II. Abstract There is clearly a need to characterize the entire catch of commercial fishermen and compare differences in abundance and species diversity to what is caught in fishery-independent gear. As we move towards a multi-species management approach, these types of data are essential. In addition, estimates of release mortality are needed for stock assessments but currently this is not being measured for fishery-dependent data. Many reef fishes captured at depths greater than ~ 20 m often have problems submerging when released by commercial fishermen. The goal of the research project was to characterize the entire (retained and discarded) catch of reef fishes from a selected commercial fisherman including total catch composition and disposition of fishes that were released. During April- November 2004, Captain Mark Marhefka dedicated one fishing trip (5-7 day duration) each month to the collection of fishery-dependent data. Date, location and collection number were recorded for each site fished by Captain Marhefka using a PDA equipped with a GPS.

An updated checklist and characterisation of the ichthyofauna (Elasmobranchii and Actinopterygii) of the Laguna de Tamiahua, Veracruz, Mexico. Acta Ichthyol. Piscat. 48 (4): 341–362. Background. Laguna de Tamiahua is ecologically and economically important as a nursery area that favours the recruitment of species that sustain traditional fisheries. It has been studied previously, though not throughout its whole area, and considering the variety of habitats that sustain these fisheries, as well as an increase in population growth that impacts the system. The objectives of this study were to present an updated list of fish species, data on special status, new records, commercial importance, dominance, density, ecotic position, and the spatial and temporal distribution of species in the lagoon, together with a comparison of Tamiahua with 14 other Gulf of Mexico lagoons. Materials and methods. Fish were collected in August and December 1996 with a Renfro beam net and an otter trawl from different habitats throughout the lagoon. The species were identified, classified in relation to special status, new records, commercial importance, density, dominance, ecotic position, and spatial distribution patterns.
