The epifauna comprises I those species occurring on the substrate, while the infauna included the I animals living within it (Petersen, 1913; Thorson, 1957). Closely associated with the benthos are the demersal fishes and such bottom-dwelling, motile I invertebrates such as shrimp and crabs. A large number of colonial forms, including sponges, cnidarians, bryozoans, I and as cfdf.ans, are present in the epifauna. Such taxa are difficult or virtually I impossible to either sample quantitatively or enumerate in quantitative samples. As a result, the epifauna generally receives little more than cursory attention I in most studies on benthic ecology except in studies on fouling organisms. Yet these animals are a very important component of the benthos, both economi- I cally and ecologically (Pratt, 1973). It is not coincidental that diversity I and biomass of fishes and other nektonic species are often maximal near hard, "live bottom" areas, natural and artificial reefs, wrecks, breakwaters, piers, I and platforms (Bearden and McKenzie, 1973; Colunga and Stone, 1974; Menzies, et al., 1966; Pearse and Williams, 1951; Roberts and Able, 1974). Epifaunal I species provide food, substrate, and shelter for a variety or organisms, alter I sedimentation patterns (Emery, Stephenson, and Hedgpeth, 1957), and serve as potentially valuable environmental indicators (Stephens and Davies, 1974). Foul- I ing organisms (Woods Hole Oceanographic Institution, 1952), as well as oyster drills and starfish (Gal.t soff , 1964) are all of negative economic value, while I the oyster is one of the most commercially valuable of all benthic invertebrates. I Fisheries also exist in other areas for a variety of other epifaunal invertebrates. While Thorson (1957) estimated .that the total area of the ocean colonized by epifaunal I organisms is substantially below that occupied by the infauna, the difference is much less pronounced in shallow water areas, especially in temperate or tropical I I -2- I areas. Epifaunal biomass is particularly substantial in many estuarine areas I where an abundance of hard substrates occur. Benthic studies were initiated as part of the South Carolina Estuarine I Survey Program at the Marine Resources Research Institute during the summer of 1973. Early in the study it became apparent that the epifauna was very poorly I known in the estuaries under investigation and should be included in the research. I The purpose of this report is to qualitatively describe the epifaunal invertebrate assemblages from a number of subtidal habitats in South Carolina estuaries. A I complete census of all epifaunal species present in the state or even collected during this study was obviously not feasible, considering both taxonomic problems I and the limited time and personnel available for the study. Accordingly, this I report includes only the more common species or those we otherwise felt competent to identify. The community structure of subtidal benthic communities in the I Edisto and Santee River estuaries, based on qualitative and quantitative samples, will be outlined in a forthcoming report (Calder, Boothe, and Maclin, 1977). I I I I I I I I I 1 -3- 1 IIATERIALS MiD METHODS 1 The study area encompassed the region from the mouth to the head of various estuarine systems across the South Carolina coastal zone. Collections were 1 made aboard the R/V Anita at 31 stations between Hinyah Bay and Calibogue Sound during January, April, August, and October of 1974, and at 29 stations during I the .same months in 1975 (Fig. 1, Table 1). Tows of three to five minutes were I made at each station during early flood tide using a 30 kg modified oyster dredge. TI,e dredge consisted of a rectangular steel frame measuring 80 cm across the I mouth, with a 1.5 m long bag of 2.5 em stretch mesh polypropylene. A skirt of I:" "";::::."~·l'terlacingmetal rings protected the bag from chafing. A typical catch con- sisted of from 10-20 liters of shells, mud, detritus, and benthic organisms. 1 Tows longer than five minutes usually resulted in clogged dredge bags and damaged specimens. After preliminary sorting of the catch on station, unidenti- I fied epifauna~ organisms and a representative sample of firm substrates were preserved in 10% ne.tralized formaldehyde solution and returned to the laboratory 1 for microscopic examination. I Bottom salinity samples were taken prior to each dredge tow using a 6-liter Van Dorn bottle. 'Lvese samples were analyzed in the laboratory using a 1 Beckman RS7B induction salinometer. The bottom type at each station was deter- mined from a series of three samples taken with a 0.13 m2 modified Petersen I grab. Depth was recorded using a Raytheon DE-725B recording depth fathometer. I A number of decapods such as shrimp and portunid crabs, while not epifaunal in the strictest senset were included in this report. Infaunal species taken I in dredge collections were excluded. The epifauna of pelagic Sargassum and beach drift, the intertidal zone, and nearshore and offshore areas have not I been included. I • EO I -4- '.

Wall , Christopher D. Stallings College of Marine Science, University of South Florida, 140 7th Ave, St Petersburg, FL 33705, USA ARTICLE INFO ABSTRACT Keywords: Composition of marine epibenthic communities are influenced by both physical and biotic processes. For in- West Florida Shelf stance, the larval supply and cues that influence colonization (physical), as well as the growth and mortality of Coral individuals (biotoic), may differ across location and reef type. Determining the relative influence of these pro- Warm temperate cesses is important to understanding how epibenthic communities can develop in a region. Using both a partial Fouling caging experiment that controlled grazing by urchins and in situ photographic surveys of epibenthic commu- Habitat heterogeneity Settlement nities, this study examined the relationship between urchin grazing and the composition of epibenthos on natural limestone and artificial reefs in the eastern Gulf of Mexico (eGOM). In the experiment, tiles that were open to urchin grazing had lower percent cover of algae (−12%) and higher cover of crustose coralline algae (CCA) (13%) than those that excluded urchins. Patterns in tile cover were likely the result of CCA either resisting grazing mortality or recolonizing exposed areas after algae were removed. Variation in colonization was ob- served between inshore and offshore reef groups. Urchin density was positively correlated with the structural complexity of the habitats, which was higher on artificial reefs than natural ones, a factor that potentially had important effects on several observed patterns.

    South Carolina Department of Natural Resources

    FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas.

    LARVAL DEVELOPMENT OF THE SPIDER CRAB, LIBINIA EMARGINATA (MAJIDAE)l D. MICHAEL JOHNS2 AND WILLIAM H. LANG3 ABSTRACT Larval development ofthe spider crab, Libinia emarginata, consists oftwo zoeal stages and megalopa. Laboratory-reared larvae (South Carolina and Rhode Island) are described and compared with planktonic larvae from Narragansett Bay, R.I. No significant variations in morphology were found between laboratory-cultured larvae and "wild" larvae from plankton catches; first stage zoea from South Carolina were smaller than Rhode Island specimens. Using Artemia diets, the best percentage survival in culture was found to be 20°C for Rhode Island larvae and 25°C for South Carolina larvae. Zoeal stages show little difference from larvae ofL. dubia; however, the megalopae ofthe two species can be differentiated by the number of protuberances on the cardiac region of the carapace. Larval stages have previously been described for a ters and development times. Characteristics number of species from the family Majidae (San­ which distinguish L. emarginata larvae from the difer and Van Engel 1971, 1972).

    4.1.3 Coastal Migratory Pelagics Description and Distribution (from CMP Am 15) The coastal migratory pelagics management unit includes cero (Scomberomous regalis), cobia (Rachycentron canadum), king mackerel (Scomberomous cavalla), Spanish mackerel (Scomberomorus maculatus) and little tunny (Euthynnus alleterattus). The mackerels and tuna in this management unit are often referred to as ―scombrids.‖ The family Scombridae includes tunas, mackerels and bonitos. They are among the most important commercial and sport fishes. The habitat of adults in the coastal pelagic management unit is the coastal waters out to the edge of the continental shelf in the Atlantic Ocean. Within the area, the occurrence of coastal migratory pelagic species is governed by temperature and salinity. All species are seldom found in water temperatures less than 20°C. Salinity preference varies, but these species generally prefer high salinity. The scombrids prefer high salinities, but less than 36 ppt. Salinity preference of little tunny and cobia is not well defined. The larval habitat of all species in the coastal pelagic management unit is the water column. Within the spawning area, eggs and larvae are concentrated in the surface waters. (from PH draft Mackerel Am. 18) King Mackerel King mackerel is a marine pelagic species that is found throughout the Gulf of Mexico and Caribbean Sea and along the western Atlantic from the Gulf of Maine to Brazil and from the shore to 200 meter depths. Adults are known to spawn in areas of low turbidity, with salinity and temperatures of approximately 30 ppt and 27°C, respectively. There are major spawning areas off Louisiana and Texas in the Gulf (McEachran and Finucane 1979); and off the Carolinas, Cape Canaveral, and Miami in the western Atlantic (Wollam 1970; Schekter 1971; Mayo 1973).

    Invest. Mar., Valparaíso, 34(2): 23-35, 2006 Biogeography of Chilean sea anemones 23 Biodiversity of Chilean sea anemones (Cnidaria: Anthozoa): distribution patterns and zoogeographic implications, including new records for the fjord region* Verena Häussermann Fundación Huinay, Departamento de Biología Marina, Universidad Austral de Chile Casilla 567, Valdivia, Chile ABSTRACT. The present paper provides a complete zoogeographical analysis of the sea anemones (Actiniaria and Corallimorpharia) of continental Chile. The species described in the primary literature are listed, including depth and distribution records. Records and the taxonomic status of many eastern South Pacific species are doubtful and need revision and confirmation. Since 1994, we have collected more than 1200 specimens belonging to at least 41 species of Actiniaria and Corallimorpharia. We sampled more than 170 sites along the Chilean coast between Arica (18°30’S, 70°19’W) and the Straits of Magellan (53°36’S, 70°56’W) from the intertidal to 40 m depth. The results of three recent expeditions to the Guaitecas Islands (44°S) and the Central Patagonian Zone (48°-52°S) are included in this study. In the fjord Comau, an ROV was used to detect the bathymetrical distribution of sea anemones down to 255 m. A distribution map of the studied shallow water sea anemones is given. The northern part of the fjord region is inhabited by the most species (27). The results show the continuation of species characteristic for the exposed coast south of 42°S and the joining of typical fjord species at this latitude. This differs from the classical concept of an abrupt change in the faunal composition south of 42°S.

Lecce-Monteroni 73100 Lecce RESEARCH ARTICLE ITALY Abstract 1 - Lagoons are ecotones between freshwater, marine and terrestrial biotopes, characterized by internal ecosystem heterogeneity, due to patchy spatial and temporal distribution of biotic and abiotic components, and inter-ecosystem heterogeneity, due to the various terrestrial-freshwater and freshwater-marine interfaces. 2 - Here, we carried out an analysis of environmental heterogeneity and benthic macro-invertebrate guilds in a sample of 26 Italian lagoons based on literature produced over a 25 year period.. 3 - In all, 944 taxonomic units, belonging to 13 phyla, 106 orders and 343 families, were recorded. Most species had a very restricted geographic distribution range. 75% of the macroinvertebrate taxa were observed in less than three of the twenty-six lagoons considered. 4 - Similarity among macroinvertebrate guilds in lagoon ecosystems was remarkably low, ranging from 10.5%±7.5% to 34.2%±14.4% depending on the level of taxonomic resolution. 5 - Taxonomic heterogeneity was due to both differences in species richness and to differences in species composition: width of seaward outlet, lagoon surface area and water salinity were the most important factors affecting species richness, together accounting for up to 75% of observed inter-lagoon heterogeneity, while distance between lagoons was the most significant factor affecting similarity of species composition.
