To investigate the patterns of noc- turnal cross-boundary movements of fish and quantify trophic connectivity, fish were sampled at night with gillnets set along the boundaries between dominant habitat types (coral reef/seagrass and mangrove/ seagrass) in southwestern Puerto Rico. Fish movement across adjacent boundary patches were equivalent at both coral reefs and mangroves. Prey biomass transfer was greater from seagrass to coral reefs (0.016 kg/km) and from mangroves to seagrass (0.006 kg/km) but not statistically significant, indicating a balance of flow between adjacent habitats. Pelagic species (jacks, sharks, rays) accounted for 37% of prey biomass transport at coral reef/seagrass and 46% at mangrove/seagrass while grunts and snappers accounted for 7% and 15%, respectively. This study indicated that coral reefs and mangroves serve as a feeding area for a wide range of multi-habitat fish species. Crabs were the most frequent prey item in fish leaving coral reefs while molluscs were observed slightly more frequently than crabs in fish entering coral reefs. For most prey types, biomass exported from mangroves was greater than biomass imported. The information on direction of fish movement together with analysis of prey data provided strong evidence of ecological linkages between distinct adjacent habitat types and highlighted the need for greater inclusion of a mosaic of multiple habitats when attempting to understand ecosystem function including the spatial transfer of energy across the seascape.

  • Fish Assemblage of the Mamanguape Environmental Protection Area, NE Brazil: Abundance, Composition and Microhabitat Availability Along the Mangrove-Reef Gradient
    Neotropical Ichthyology, 10(1): 109-122, 2012 Copyright © 2012 Sociedade Brasileira de Ictiologia Fish assemblage of the Mamanguape Environmental Protection Area, NE Brazil: abundance, composition and microhabitat availability along the mangrove-reef gradient Josias Henrique de Amorim Xavier1, Cesar Augusto Marcelino Mendes Cordeiro2, Gabrielle Dantas Tenório1, Aline de Farias Diniz1, Eugenio Pacelli Nunes Paulo Júnior1, Ricardo S. Rosa1 and Ierecê Lucena Rosa1 Reefs, mangroves and seagrass biotopes often occur in close association, forming a complex and highly productive ecosystem that provide significant ecologic and economic goods and services. Different anthropogenic disturbances are increasingly affecting these tropical coastal habitats leading to growing conservation concern. In this field-based study, we used a visual census technique (belt transects 50 m x 2 m) to investigate the interactions between fishes and microhabitats at the Mamanguape Mangrove-Reef system, NE Brazil. Overall, 144 belt transects were performed from October 2007 to September 2008 to assess the structure of the fish assemblage. Fish trophic groups and life stage (juveniles and adults) were recorded according to literature, the percent cover of the substrate was estimated using the point contact method. Our results revealed that fish composition gradually changed from the Estuarine to the Reef zone, and that fish assemblage was strongly related to the microhabitat availability, as suggested by the predominance of carnivores at the Estuarine zone and presence of herbivores at the Reef zone. Fish abundance and diversity were higher in the Reef zone and estuary margins, highlighting the importance of structural complexity. A pattern of nursery area utilization, with larger specimens at the Transition and Reef Zone and smaller individuals at the Estuarine zone, was recorded for Abudefduf saxatilis, Anisotremus surinamensis, Lutjanus alexandrei, and Lutjanus jocu.

A series of 35 larvae 2.4 mm NL to 21.5 mm SL from 2 to 30 days old or older (larvae of unknown age) was studied for pigmentation characteristics. Cleared and stained specimens were examined for meristic and osteological development. Cartilaginous neural and haemal arches develop first anteriorly, at the center, and posteriorly, above and below the notochord, but ossification of the vertebral column is from anterior in a posterior direction. Epipleural rib pairs develop from bone, but pleural rib pairs develop from cartilage first and then ossify. The second dorsal, anal and caudal fins develop rays first and simultaneously, followed by first dorsal fin spine development. The pectoral and pelvic fins are the last of all fins to develop rays. All bones basic to a perciform pectoral girdle develop with cartilaginous radials present between the pectoral fin ray bases. Development and structure of pre dorsal bones and dorsal and anal fin pterygiophores were studied. All bones basic to a perciform caudal complex developed and no fusion of any of these bones was observed in the adults. Radial cartilages developed ventrad in the hypural complex. The hyoid arches originated from cartilage but the branchiostegal rays formed from bone. The development and anatomy of the branchial skeleton were studied. Spines develop on the four bones of the opercular series in larvae and juveniles but are absent in the adults.

  • Potential of Pigeon Creek As a Nursery Habitat for Juvenile Reef Fish
    ORIGINAL ARTICLE Potential of Pigeon Creek, San Salvador, Bahamas, As Nursery Habitat for Juvenile Reef Fish Ian C. Conboy1 Northeast Fisheries Science Center, Woods Hole, MA James M. Haynes The College at Brockport, State University of New York, Brockport, NY ABSTRACT This project assessed the significance of Pigeon Creek, San Salvador, Bahamas as a nursery habitat for coral reef fishes. Pigeon Creek’s perimeter is lined with mangrove and limestone bedrock. The bottom is sand or sea grass and ranges in depth from exposed at low tide to a 3-m deep, tide-scoured channel. In June 2006 and January 2007, fish were counted and their maturity was recorded while sampling 112 of 309 possible 50-m transects along the perimeter of the Pigeon Creek. Excluding silversides (Atherinidae, 52% of fish counted), six families each comprised more than 1% of the total abundance (Scaridae/parrotfishes, 35.3%; Lutjanidae/snappers, 23.9%; Haemulidae/grunts, 21.0%; Gerreidae/mojarras, 8.5%; Pomacentridae/damselfishes, 6.1%; Labridae/wrasses, 2.4%). There were few differences in effort-adjusted counts among habitats (mangrove, bedrock, mixed), sections (north, middle, southwest) and seasons (summer 2006 and winter 2007). Red mangrove (Rhizophora mangle), covering 68% of the perimeter was where 62% of the fish were counted. Snappers, grunts and parrot fishes are important food fishes and significant families in terms of reef ecology around San Salvador. Mangrove was the most important habitat for snappers and grunts; bedrock was most important for parrot fishes. The southwest section was important for snappers, grunts and parrot fishes, the north section for grunts and parrot fishes, and the middle section for snappers.

NEMETH, and RICHARD S. APPELDOORN Department of Marine Sciences, University of Puerto Rico, Mayagüez, Puerto Rico 00681 ABSTRACT Coral reef fishes use a variety of habitats throughout daily, ontogenetic, and spawning migrations, therefore requiring a suite of habitats to complete their life cycle. The use of multiple habitats by grunts (Haemulidae) and snappers (Lutjanidae) was investigated at Mona Island, a remote island off western Puerto Rico. The objective of this study was to determine if the distribution of three different life stages was random in relation to benthic habitat types. Coral reef fish were sampled throughout all habitat types randomly over a period of six months. For seven species of grunts and snappers median fork length was significantly different by habitat type identifying critical habitats for juveniles distinct from adult habitats. Within a life stage significant differences were observed in fish density by habitat type. Early juvenile grunts and snappers were more abundant in habitats of depths less than 5 m, mainly in rocky shores and seagrass areas with patches of coral or other hard structures. Larger juveniles were significantly more abundant in depths less than 5m in coral dominated habitats. Adults were abundant throughout the habitats of all depth ranges, except for two species Haemulon chrysargyreum and Lutjanus mahogoni, which were limited to shallower habitats.

Phylogenetic analyses were Fish performed on 97 grunt species based on sequence data collected from seven loci. Divergence time estimation Functional traits indicates that Haemulidae originated during the mid Eocene (54.7–42.3 Ma) but that the major lineages were Morphospace formed during the mid-Oligocene 30–25 Ma. We propose a new classification that reflects the phylogenetic Macroevolution history of grunts. Overall the pattern of morphological and functional diversification in grunts appears to be Zooplanktivore strongly linked with feeding ecology. Feeding traits and the first principal component of body shape strongly separate species that feed in benthic and pelagic habitats. The benthic-to-pelagic axis has been the major axis of ecomorphological diversification in this important group of tropical shoreline fishes, with about 13 transitions between feeding habitats that have had major consequences for head and body morphology.
