Life History And Courtship Behavior Of Black Perch, Embiotoca Jacksoni (Teleostomi: Embiotocidae), From Southern California, Bridgette Froeschke, Larry Allen, Daniel Pondella

Daniel Pondella

The black perch, Embiotoca jacksoni Agassiz, 1853, is a common reef fish associated with nearshore marine habitats of California, with the majority of the population occurring within the Southern California Bight. Black perch were collected throughout southern California from Santa Barbara to Carlsbad, including Santa Catalina Island, to determine their physical characteristics, growth, sex ratio, periodicity of reproduction, and length of gestation. Courtship observations were conducted using scuba along the King Harbor Breakwater in Redondo Beach, California, from January 2004 to December 2005 to verify periodicity of courting and associated reproductive behaviors. Specimens captured ranged from 75 to 220 mm …

Effect Of Wave Action On Movement In The Owl Limpet, Lottia Gigantea, In Santa Cruz, California, William G. Wright, James W. Nybakken

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The critical role of wave energy in the ecology of nearshore organisms is widely accepted, based primarily on biotic correlations over large scales of time and space. Much less is known about how large waves impact the behavioral ecology of individual organisms. Theoretical considerations and measurements of tenacity predict that intertidal gastropods should minimize the chances of dislodgement during periods of high waves by remaining stationary. We tested this prediction by observing a population of the owl limpet, Lottia gigantea G. B. Sowerby I, 1834, in a range of sea conditions. We found the proportion of the population moving during …

Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia

Fisheries management papers

In recent times, the Department of Fisheries has received representations from both sectors about the ongoing interaction of the fisheries and their respective management settings. As a result, a decision was made to comprehensively review the fisheries, taking into account matters of fishery sustainability and gear interactions, together with industry economics and market considerations. The review has also addressed research requirements to ensure an appropriate scientific basis for decision-making into the future.

Behavioral Enhancement Of Onshore Transport By Postlarval Caribbean Spiny Lobster (Panulirus Argus), Jason Seth Goldstein

Biological Sciences Theses & Dissertations

The onshore transport of meroplanktonic marine larvae or postlarvae is often complex, involving both active (i.e., behavior, swimming) and passive (i.e., oceanographic elements) transport mechanisms. Behaviors that modify passive transport have presumably evolved to situate larvae in settlement habitats where survival is enhanced. Active transport mechanisms have not been described for the puerulus postlarvae of any species of spiny lobster, despite their extraordinary mobility and known preference for specific settlement habitats. In the Florida Keys, for example, Caribbean spiny lobster (Panulirus argus) pueruli travel from oceanic waters into coastal areas where they settle within bushy, red macroalgae. I …

Phytoplankton Productivity In The Tidal Regions Of Four Chesapeake Bay (U.S.A.) Tributaries, Kneeland K. Nesius, Harold G. Marshall, Todd A. Egerton

Virginia Journal of Science

Monthly and annual phytoplankton productivity rates of four Virginia tidal rivers were determined based on a 12-year monitoring study that included sampling stations from tidal freshwater, oligohaline, and mesohaline regions in these rivers. The mean monthly rates and range at these locations were 5.52 (Dec.) to 175.12 (Aug.) mg C m^-3 h^-1 for tidal freshwater, 12.21 (Jan.) to 149.90 (May) mg C m^-3 h^-1 in oligohaline regions, and 16.20 (Jan.) to 151.33 (May) mg C m^-3 h^-1 for the mesohaline. The estimated mean annual 12 year productivity for the different Virginia river sites in …

Glow Sticks As Effective Bait For Capturing Aquatic Amphibians In Funnel Traps, Kristine L. Grayson, Andrew W. Roe

Biology Faculty Publications

Funnel traps of various designs have been used to capture adults and larvae of aquatic amphibians (e.g., Buech and Egeland 2002; Richter 1995). Most studies use unbaited funnel traps to capture amphibians while others have used shrimp or salmon eggs (Adams et al. 1997). Light traps and light sticks are commonly used in studies of fish, particularly larvae (Doherty 1987; Marchetti et al. 2004), but have not been widely used to capture amphibians. Glow sticks have been mentioned briefly in the literature as a means to increase capture rates of aquatic amphibians (Smith and Rettig 1996), but no studies have …

Bottom-Up And Climatic Forcing On The Nesting And Foraging Ecology Of Leatherback Turtles (Dermochelys Coriacea), Vincent Sellitto Saba

Dissertations, Theses, and Masters Projects

There currently exists a major dichotomy in the nesting population trends of leatherback turtles (Dermochelys coriacea) worldwide. Eastern Pacific populations have been declining precipitously while populations in the Atlantic and western Indian Oceans have been either stable or increasing. The populations in the western Pacific have also declined with some near extirpation. Factors attributed to the Pacific population decline are incidental fishery mortality and egg harvesting. Fishery mortality occurs throughout all basins, and with the exception of the western Pacific population, egg harvesting has not been a major factor at the major nesting complexes for almost two decades. Populations in …

Fisheries Independent Assessment Of A Returning Fishery: Abundance Of Juvenile White Seabass (Atractoscion Nobilis) In The Shallow Nearshore Waters Of The Southern California Bight, 1995–2005, Larry G. Allen, Daniel J. Pondella Ii, Michael A. Shane

Daniel Pondella

Nearshore, coastal and embayment areas off southern California were sampled to determine the spatial and temporal patterns abundance and size distributions of young white seabass in the shallow (5–14 m) waters from Santa Barbara south to Imperial Beach off San Diego. A total of 19 stations, 13 in nearshore coastal waters and 6 in embayments, dispersed along the Southern California Bight were surveyed in each sampling month using 45.7 m variable mesh, monofilament gill nets. In the 11-year period of sampling (April 1995–June 2005), a total of 8075 juvenile white seabass was captured in 42 sampling months. The mean catch-per-unit-effort …
