A Test Of The Area Of Refuge Hypothesis In Indo-Pacific Marine Biogeography, Jonnell C. Sanciangco

Biological Sciences Theses & Dissertations

Many hypotheses have been proposed to explain the marine biogeographic patterns of species richness of the Indo-Pacific. One of these hypotheses suggests that available habitat area is the main predictor of species richness. This is the basis for the area of refuge hypothesis that attempts to explain the global maxima of species richness found in the Coral Triangle, the area encompassing mostly the Philippines, Indonesia, and Malaysia. This species-area effect also has habitat heterogeneity as a potential component. The purpose of this study is to test the effects of habitat availability predictors, such as shallow water area and coastline length …

Impacts Of The Spotted Spiny Lobster (Panulirus Guttatus) On The Long-Spined Sea Urchin (Diadema Antillarum) And Patch Reef Communities In The Florida Keys, Meredith D. Kintzing

Biological Sciences Theses & Dissertations

Caribbean coral reefs have undergone a phase shift from a system dominated by corals to one where algae are pervasive. This shift was precipitated by the loss of herbivores, including the mass mortality of the long spined sea urchin (Diadema antillarum), coupled with disease and the recruitment failure of hermatypic corals. Diadema populations have recovered in some areas of the Caribbean, but are still below historical levels in the Florida Keys, likely due to low larval supply coupled with predation on juveniles. Lobsters are sea urchin predators in other systems and the spotted spiny lobster (Panulirus guttatus …

Fisheries Research Report No.196 - Management Of Bioeroding Sponges In Wild Stocks Of Pinctada Maxima In Western Australia, Sabine Daume, Jane Fromont, Anthony M. Hart

Fisheries Research Reports

Final FRDC Report – Project 2005/074

The Western Australian fishery is the only remaining significant fishery for pearl oysters in the world and comprises most of the exported pearl product of Australia, currently worth around $125 million annually. The majority of pearl shells used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller ‘culture’ shell (4-5 years age class, 120mm - 160mm shell length) that are more suitable for growing pearls, leaving larger MOP oysters (6+ age class, 175mm+) on the fishing grounds.

Silver-lipped pearl oysters (Pinctada …

Fisheries Management Paper No.245 - Aquaculture Of Coral, Live Rocks And Associated Products. Aquaculture Policy, Department Of Fisheries, Western Australia

Fisheries Management Papers

Aquarium enthusiasts use corals, live rock and associated products (e.g. live sand) for display and to maintain healthy water quality conditions in their marine aquariums. There is a large and growing market for these products. While the wild harvest fisheries for aquarium products in Western Australia are sustainably managed, output is capped, so increased product is needed to meet the market demand. With a trend towards the capping of wild harvest and additional pressures, such as the introduction of Marine Parks and other marine protected areas, the aquaculture of these products is set for industry development and expansion.

Fisheries Research Report No.157 - The Western Rock Lobster Fishery 2003/2004 And 2004/2005, Simon De Lestang, E H. Barker

Fisheries Research Reports

The 2003/2004 season produced the second highest catch recorded to date (13,684 tonnes), up markedly on the previous season’s catch of 11,415 t. Nominal effort in 2003/2004 (10,180,444 pot lifts) did not vary by nearly as much as did the catch, with total pot lifts declining only slightly (<1%) on the previous season. Season 2004/2005 produced a catch of 12, 236 tonnes, down on the previous season’s catch of 13,684 t. Similar to the catch, total nominal effort in 2004/2005 (9,789,671 pot lifts) also declined fairly substantially (4%) on the previous season. Recreational catches for the above two seasons were also down on their respective previous seasons by 52 and 11% each.

Puerulus settlement coast wide during 2003/2004 was below average, especially towards the southern and northern extremes of the fishery (Port Gregory and Jurien Bay south). This was also the case during the following season (2004/2005), although the poor settlement was more evenly spread across the entire fishery. Catch predictions from these …

Fisheries Research Report No. 174 - Spatial Scales Of Exploitation Among Populatons Of Demersal Scalefish : Implications For Management. Part 2: Stock Structure And Biology Of Two Indicator Species, West Australian Dhufish (Glaucosoma Hebraicum) And Pink Snapper (Pagrus Auratus) In The West Coast Bioregion, Department Of Fisheries, Western Australia

Fisheries Research Reports

Final FRDC Report - Project 2003/052

EDITORS: R. Lenanton, J. StJohn, I. Keay, C. Wakefield, G. Jackson, B. Wise and D. Gaughan

West Australian dhufish is endemic to shelf waters of south-western Western Australia (WA). In contrast, snapper (known as “pink snapper” in WA) has a continuous distribution around the southern coastline of mainland Australia and in New Zealand. Dhufish and snapper are the two most important exploited demersal scalefish species in the West Coast Bioregion (WCB) of WA, which extends from Kalbarri (27°S) to Augusta (35°S). This study examined regional variation in the biology of the two species, their …

Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann

All Theses And Dissertations

Populations of the gastropod Nucella lapillus are polymorphic for shell color, with light-colored shells predominating on warmer, wave-protected shores and dark-colored shells limited primarily to cooler, wave-exposed shores. During thermal stress, darker shells attain higher body temperatures than lighter shells. These results suggest that heat stress may determine field distribution patterns. However, there is currently little evidence of physiological consequences of thermal stress in these organisms. Following the guiding hypothesis that heat stress leads to cellular energy depletion, we explored whether the central energy regulator AMP-activated Protein Kinase (AMPK) is activated by heat stress. We compared this response in both …

The Functions And Values Of Fringing Salt Marshes In Northern New England, Usa, Pamela A. Morgan, David M. Burdick, Frederick T. Short

Environmental Studies Faculty Publications

Although large salt marshes of the northeastern United States have been studied extensively, very little is known about the smaller, fringing marshes in this area, despite the fact that they are a common habitat type. We compared the functions and values of five fringing salt marshes (FM) to those of five meadow marshes (MM) along the southern Maine/New Hampshire coast. Specifically we compared their primary production, soil organic matter content, plant diversity, sediment trapping ability and wave dampening properties. Also explored were the relationships between these functions and several physical characteristics at each site, including soil salinity, percent surface slope, …

Fisheries Research Report No. 183 - Development Of A Long-Term Program To Monitor Coastal Communities Within The Swan Region, Lynda M. Bellchambers

Fisheries Research Reports

Marine benthic communities along the metropolitan coast of Western Australia are varied and unique. The southward flowing Leeuwin Current brings warm water and tropical recruits whilst the cooler counter current, the Capes Current, brings the temperate recruits. The result is a mosaic of tropical species intermingled with the dominant temperate species. These areas sustain varied fish and invertebrate communities making this coast a highly desirable location for recreational and commercial use. Management strategies are in place that attempt to maintain the sustainability of this area including various fishery restrictions and the implementation of areas zoned as sanctuary zones (no-take). However, …

On The Movement Of Beluga Whales In Cook Inlet, Alaska: Simulations Of Tidal And Environmental Impacts Using A Hydrodynamic Inundation Model, Tal Ezer, Roderick Hobbs, Lie-Yauw Oey

CCPO Publications

The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and were placed on the list in October 2008, just before this article went to press). In order to study environmental and hydrodynamic impacts on the belugas' movements and survival in the unique habitat of the inlet, a three-dimensional ocean circulation and inundation model is combined with satellite-tracked beluga whale data. Model-wale data comparisons from two whale paths during a five-day period (september 17-21, 2000) covering 10 tidal cycles suggest …

Fisheries Research Report No. 181 - Developing Long-Term Indicators For The Sub-Tidal Embayment Communities Of Cockburn Sound, Danielle Johnston, C. Wakefield, A Sampey, J Fromont, D C. Harris

Fisheries Research Reports

Swan Catchment Council Project – 01-0506 T 2006 – 2008 program

The geomorphology of Cockburn Sound is unique to the lower west coast of Australia due to the relative paucity of sheltered nearshore marine embayments along this coastline. Numerous studies on many of the commercially and/or recreationally important species that inhabit Cockburn Sound have demonstrated that for many of them this marine embayment constitutes an integral part of their life history. Since the commencement of industrial and urban development in the mid 1950s, in the waters and along the shores of Cockburn Sound, the marine fauna utilising this area have …

Fisheries Research Report No. 171 - Evaluation Of Exclusion Grids To Reduce The Bycatch Of Dolphins, Turtles, Sharks And Rays In The Pilbara Trawl Fishery, Peter Stephenson, S. Wells, J. A. King

DBIF funded Project.

Considerable research on the documention of the bycatch of cetaceans, seals, turtles, and sea lions during trawl fishing operations has been undertaken worldwide. These include the Argentinean squid and hake trawl fisheries (Crespo et al., 1997; Fertl & Leatherwood, 1997), the Dutch pelagic trawl fishery (Couperus, 1997), the NE Atlantic pelagic trawl fishery (Tregenza & Collet, 1998) and the New Zealand squid fishery (Fishing News International, 2005).

In the Pilbara Fish Trawl Fishery, operating off the coast of Western Australia protected species including dolphins, turtles, sawfish, sea snakes as well as numerous sharks and ray species have …

Fisheries Research Report No. 175 - An Assessment Of The Finfish Catch By Recreational Fishers, Tour Operators, Commercial Lobster Fishers And Commercial Wetline Fishers From The Houtman Abrolhos Islands During 2006, Neil R. Sumner

Fisheries Research Reports

The catch of finfish from the Houtman Abrolhos Islands was estimated for recreational boats, tour operators, commercial rock lobster fishers and occupants of their camps on the islands. Separate methods were used for each of the different sectors due to the variation in fishing activities. Recreational boats and commercial rock lobster fishers were surveyed to determine catches, whereas the catches by tour operator and commercial wet-line fishers were determined from their compulsory catch and effort returns submitted to the Department of Fisheries.

The reported commercial wetline catch for pink snapper, sweetlip emperor and Western Australian dhufish greatly exceeded the combined …

Fisheries Research Report No. 176 - Regrowth Of Pilchard (Sardinops Sagax) Stocks Off Southern Wa Following The Mass Mortality Event Of 1998/99, Daniel J. Gaughan, M Craine, Peter Stephenson, Timothy I. Leary, Paul Lewis

Fisheries Research Reports

Final FRDC Report – Project 2000/135

This project produced time series of estimates of spawning biomass for pilchards in four purse seine management zones in Western Australia, three on the south coast and one on the west coast. The pilchard stocks in Western Australia have recovered strongly since the 1998/99 mass mortality.

This project has shown that the fishery independent and fishery dependent methods applied to Western Australia’s pilchard fisheries cannot provide precise estimates of the size of the pilchard spawning biomass in each management region. Although the trends indicated by the age-structured simulation model are reliable and provide good …

Rapid Evolution In Introduced Species, ‘Invasive Traits’ And Recipient Communities: Challenges For Predicting Invasive Potential, Kenneth D. Whitney, Christopher A. Gabler

School of Earth, Environmental, & Marine Sciences Faculty Publications

The damaging effects of invasive organisms have triggered the development of Invasive Species Predictive Schemes (ISPS). These schemes evaluate biological and historical characteristics of species and prioritize those that should be the focus of exclusion, quarantine, and/or control. However, it is not clear how commonly these schemes take microevolutionary considerations into account. We review the recent literature and find that rapid evolutionary changes are common during invasions. These evolutionary changes include rapid adaptation of invaders to new environments, effects of hybridization, and evolution in recipient communities. Strikingly, we document 38 species in which the specific traits commonly associated with invasive …

Fisheries Research Report No. 170 - Biomass And Commercial Catch Estimates For Abalone Stocks In Areas Proposed As Sanctuary Zones For The Capes Marine Park, A. Hesp, Neil R. Loneragan, Norman G. Hall, H T. Kobryn, A.M. Hart, Frank Fabris, Jeremy Prince

Fisheries Research Reports

This study was undertaken to estimate the biomasses, biologically sustainable catches and current average annual commercial catches of three fished species of abalone, Haliotis roei (Roei), Haliotis laevigata (Greenlip) and Haliotis conicopora (Brownlip) in the proposed sanctuaries of the Capes Marine Park, south-western Australia. The current annual, catch estimates represent the catches that would be foregone by commercial fishers if the sanctuaries are implemented and will be used to evaluate the potential compensation to fishers (not part of this study). The biomass and catch estimates for each species in the proposed sanctuaries were estimated from a combination of scientific survey …

Fisheries Research Report No. 173 - Evaluation Of The Effectiveness Of Reducing Dolphin Catches With Pingers And Exclusion Grids In The Pilbara Trawl Fishery, Peter Stephenson, S. Wells

Fisheries Research Reports

Final FRDC Report – Project 2004/068

“Savewave” acoustic pingers were trialed on one vessel to determine if they would deter dolphins entering the trawl net. During daylight hours, the pingers were deployed on alternate shots in the configuration recommended by the manufacturer. On the other alternate shots, no pingers were deployed. A video camera in an underwater housing was attached to the headrope facing downstream for 18 trawl shots. On the 14 shots where usable video footage was obtained (11 with pingers deployed and 7 with pingers not deployed) the number of dolphins viewed in the camera frame was counted …

Fisheries Research Report No.172 - Identifying Obstacles To Profitably Growing Out Western Rock Lobsters, Roy Melville-Smith, Danielle Johnston, B. Johnston, N. J. Thomson

Fisheries Research Reports

A Report Prepared for the Aquaculture Development Council.

The cost of growing out western rock lobsters from pueruli to marketable-sized lobsters has been modeled from available information. The model uses different scenarios of survival rates, marketing weights, market prices, feed costs, puerulus prices, labour costs, puerulus compensation costs, discount rates and capital costs. The sensitivity of estimated profitability to various input costs and rock lobster prices was assessed by estimating the impact of changes on the estimates of net present value (NPV) internal rate of return (IRR) and benefit:cost ratio. Importantly, the aim of the study was to identify key …
