Two new Lipogramma basslets are described, L. barrettorum and L. schrieri, captured during submersible diving to 300 m depth off Curaçao, southern Caribbean. Superficially resembling L. robinsi in having 11-12 bars of pigment on the trunk, L. barrettorum is distinct from L. robinsi in having a stripe of blue-white pigment along the dorsal midline o...

The Nes subgroup of the Gobiosomatini (Teleostei: Gobiiformes: Gobiidae) is an ecologically diverse clade of fishes endemic to the western Atlantic and tropical eastern Pacific Oceans. It has been suggested that morphological characters in gobies tend to evolve via reduction and loss associated with miniaturization, and this, coupled with parallel...

In this essay I will relate the challenges associated with deep sea ocean exploration as well as the advantages and disadvantages of today’s ocean technologies based on experience with most of these systems. After nearly five decades using robotic vehicles (Remotely Operated Vehicles = ROVs and Autonomous Underwater Vehicles = AUVs) and manned subm...

Passive acoustics uses naturally occurring sounds produced by marine organisms to study their behavior, biology, and location. Ambient marine sounds are known to vary from place to place, and these sounds can be used to detect differences in habitats. Oyster toadfish, naked goby, mud crabs, and snapping shrimps inhabit oyster reefs, and they are kn...

A large spawning aggregation of Polymixia lowei, Beardfish, was documented via video and specimen collection in a deep-water (413 m) sinkhole off Key West, Florida on 5 June 2007. The use of the human-occupied submersible, Johnson-Sea-Link II, allowed for in situ observations, video documentation, and specimen collection. The maximum density (117 f...

Mangrove forest restoration projects commonly fail to achieve significant plant cover for two reasons: because there is a misunderstanding of mangrove forest hydrology, or, acceptance of the false assumption that simply planting mangroves is all that is required to establish a fully-functional mangrove ecosystem. Even restoration projects that meet...

The deep-water Oculina coral reef ecosystem is unique and exists solely off the east coast of central Florida. Oculina varicosa forms azooxanthellate colonies up to 2 m in diameter which coalesce into dense thickets on 20-m tall mounds that are thousands of years old. Recently restored videotapes that were made in the 1970s with the Johnson-Sea-Lin...

Passive acoustics is a rapidly emerging field of marine biology that until recently has received little attention from fisheries scientists and managers. In its simplest form, it is the act of listening to the sounds made by fishes and using that information as an aid in locating fish so that their habitat requirements and behaviors can be studied....

Deep-water Oculina coral reefs, which are similar in structure and development to deep-water Lophelia reefs, stretch 167 km (90 nm) at depths of 60–100 m along the eastern Florida shelf of the United States. These consist of numerous pinnacles and ridges, 3–35 m in height, that are capped with thickets of living and dead coral, Oculina varicosa. Ex...

Of all the classical oceanographic disciplines, we are probably least well equipped to further the understanding of biological oceanography through the data that will be provided by an Integrated Sustained Ocean Observing System (IOOS). What's more, some of the same federal agencies that would normally be approached to invest in the development of...

Individual sound production and aggregative choral behaviors in sciaenid fishes of the Indian River Lagoon system of east central Florida have been under study since 1977. Long term studies of sonifery augmented with equally long term life history research has allowed classification of their call behaviors relative to their ecology. Five sciaenid s...

A second specimen of L. flavescens, originally des...

Salt marshes of the Indian River Lagoon, Florida (USA) were once prolific producers of mosquitoes. Mosquitoes lay their eggs on the infrequently-flooded high marsh surface when the soil surface is exposed. The eggs hatch when the high marsh is flooded by the infrequent high tides or summer rains. To control mosquito production, most of the salt mar...

Based on papers from the conference held in Fort Pierce, Florida, in 1994, 24 main papers and 18 abstracts are published. After introductory papers on land acquisition as a tool for biological diversity protection, and geological and historical perspectives on the region's biodiversity, the contributions concentrate on the current status of species...

The geomorphology, transitional climate, geographic and shallow marine setting of the Florida peninsula extending 1,120 km from 24.6° to 30.8°N latitude has allowed great aquatic biological diversity to develop along its east coast. A compressed gradient in mean hydrologic and climatic environments and high habitat diversity along the coast and wit...

Ontogenetic increases in mouth size and changes in dentition of percoid fishes may affect the size and species of prey selected, thus influencing the fundamental trophic niche. To examine the influence of oral anatomy on prey selectivity by pinfish, Lagodon rhomboides, and snook, Centropomus undecimalis, two co-occurring percoid fishes with contras...

The capture of recently inseminated or pregnant specimens ofCarcharias taurus, Isurus paucus, I. oxyrinchus, Alopias superciliosus andA. vulpinus has allowed new information to be obtained on the reproductive biology of these species. Oophagy and embryonic cannibalism (adelphophagy) have been documented inC. taurus, but only oophagy in other lamnoi...

During operations of the Johnson Sea-Link submersible in the Lesser Antilles in 1989 and off Belize and Mexico in 1990, we collected sea cucumbers at depths between 45-235 m. Examination revealed a high incidence of tenuis larvae and exceptionally large and deeply pigmented adult pearl fish in Holothuria lentiginosa and Eostichopus arnesoni.

Color variants and behavior of scamp, Mycteroperca phenax, and gag, M. microlepis, are described from 64 submersible dives made on reef structures at depths between 20 and 100 m off the east coast of Florida from February 1977 to September 1982. These dives yielded 146 h of observations augmented with video and 35 mm photography. Both species displ...

This report covers the results and conclusions associated with nekton monitoring in a created marsh systems that was part of the Grand Harbor development in Indian River County, FL.

Hypoxia is an environmental factor that affects a myriad of behavioral, physiological and habitat-use aspects of the life-history of fish. Snook, Centropomus undecimalis (Bloch), exhibit marked ontogenetic differences in habitat-use that we propose are based on physiological constraints and environmental conditions that change as the fish grow. To...

One of a series of coastal wetland research efforts funded by Coastal Zone Management examining various aspect of wetland management including impounded, natural, restored and created systems.

Since 1981, deep reef ichthyofaunal observations and collections have been made by the Johnson-Sea-Link submersibles in the Bahama Islands at depths between 300 and 600 m. A new grammid fish species, Lipogramma flavescens, is described from a single specimen collected at a depth of 285 m at San Salvador. In addition, large adult specimens of L. evi...

Fish migration from impounded mangrove swamps through small subcells to the adjacent open estuary were examined at two sites in Brevard and St. Lucie counties with the capture of 1,193 fish using gill, trammel and cast nets, culvert traps and classical fishing techniques. No major directional movement was detected with perimeter ditch fish captures...

The present study had four primary objectives: 1. To determine the spatial and temporal-distribution of macrofaunal organisms and record associated hydrological parameters in Jack Island State Park, in the vicinity of weir in Impoundment No. 24, St. Lucie County, and during subcell water manipulation phases in the John Smith Impoundment, Brevard Co...

Seven species of mojarras (Gerreidae) were collected from three stations in the Indian River lagoon near the Sebastian Inlet, Florida over an eighteen month period to study spatial and temporal variations in occurrence and feeding habits. Two major habitats common to this area were represented in the study; a sandy beach and a seagrass flat. Of the...

The objective of this study was to determine the effects of the three flapgate designs on fish and macrocrustacean movement between the marsh and adjacent estuary. With this determination, constructive suggestions could be made on water management techniques that should be maintained to insure optimum fish and crustacean utilization of the impounde...

Four embryos of Alopias superciliosus and one of Isurus paucus were dissected and examined along with the reproductive organs of adults captured in the Florida Current off the east-central coast of Florida between latitude 26°30′N and 28°30′N. The embryos were found to contain yolk, demonstrating prenatal nutrition through intrauterine oophagy. Var...

Maximum densities of east-central Florida populations of Oostethus brachyurus lineatus, Gobiomorus dormitor, Awaous tajasica and Gobionellus pseudofasciatus occurred during winter and spring in the lower portions of freshwater tributaries to the Indian River Lagoon. All populations declined during the wet season, reaching minimum levels during peak...

Varicus marilynae n. sp. is described from two specimens (each 18.0 mm SL) taken in coastal Florida waters in depths ranging from 61 to 91 m. The new species is characterized by a flattened coalescence of the ray tips in the first four pelvic fin rays and 18-19 lateral scale rows. The head and eye are smaller than those of V. bucca Robins and Böhlk...
