Ecosystem Based Fisheries Management Case Study Report West Coast Bioregion, Warrick J. Fletcher, Jennifer Shaw, Daniel J. Gaughan, Sarah J. Metcalf

Fisheries Research Reports

This report documents the outcomes of the Western Australian Marine Science Institution (WAMSI) funded study to examine the costs and benefits of using a bioregional level, Ecosystem Based Fisheries Management (EBFM) approach. The West Coast Bioregion of Western Australia was selected as a case study and the outputs from the use of the draft national EBFM framework were critically examined to determine whether such an approach would result in more efficient and effective management of fisheries. In addition, this report examined whether this EBFM framework provided better linkages between management bodies, allowing broader marine management covering all activities and relevant …

Spatial Distribution Of Shore-Based Fishers In The Greater Perth Metropolitan Area Over Summer 2010/2011, Claire B. Smallwood, Emily A. Fisher, Brent S. Wise, Daniel J. Gaughan

Fisheries Research Reports

Aerial surveys are a useful technique for estimating numbers of recreational fishers. Following the success of a pilot study to examine the spatial patterns of recreational shore-based fishing activity in the Perth Metropolitan area from April – June 2010, another survey was conducted from December 2010 – February 2011 between Lancelin – Bunbury. More than 7,000 shorebased fishers were counted during 36 aerial flights, with significantly more recorded on morning and afternoon flights, when compared to those conducted at midday. Flights on weekends/public holidays also recorded more fishers than weekdays. The spatial distribution of fishers was variable along the coast, …

Status Of The Cockburn Sound Crab Fishery, Danielle Johnston, David Harris, Nick Caputi, Simon De Lestang, Adrian Thomson

Fisheries Research Reports

Blue swimmer crabs (Portunus armatus) (formerly Portunus pelagicus; Lai et al., 2010) in Cockburn Sound, Western Australia, are the basis of an important commercial and recreational fishery close to the Perth metropolitan area with the commercial fishery achieving a peak catch of 362 t in 1997/98 and a recreational catch of about 18 t. Commercial blue swimmer crab catches declined significantly since 2000 due to low stock abundance, resulting in the closure of the fishery in December 2006.

An Assessment Of Icthyofauna And Artisanal Fishing From The Port Of Pedregal In The Golfo De Chiriquí., Kathleen A. Carey

Independent Study Project (ISP) Collection

The artisanal fishery based out of Pedregal, on the Pacific Coast of Panama in the Chiriqui Province was studied to analyze the biodiversity and community structure of the icthyofaunal population and investigate the practices and opinions of the fishermen there. The study area is located in the Gulf of Chiriqui, and is heavily influenced by freshwater runoff from anthropogenically influenced rivers during. This is especially relevant during the rainy season. During two weeks in November, at the end of the rainy season, fishermen from one port in Pedregal were accompanied for the purposes of data collection and interviewing. The data …

A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday

Independent Study Project (ISP) Collection

In the village of Jambiani, Unguja, a Swiss NGO called Marine Cultures has established an experimental sponge farming initiative to improve local employment and support economic development. Currently, the main farming site is only accessible through SCUBA diving. This is consistent with experimental farm sites in other oceanic regions, as most are located in depths of at least five meters with sponges suspended vertically to maximize water flow exposure. Farms located in shallower water may not be conducive to sponge growth due to highly variable environmental conditions; however, no conclusive research has been conducted on this matter (Duckworth 2009). Nonetheless, …

What Is The Value Of A Sea Turtle?: A Case Study Of The Conservation Ethics Of Sea Turtle Fishermen In The Caribbean Coast Of Nicaragua, Alicia Conte

Independent Study Project (ISP) Collection

The sea turtle populations on the Caribbean Coast of Nicaragua have dramatically decreased as a result of human use and consumption. All species of sea turtles are endangered and at risk of extinction. This is an environmental issue because if sea turtles go extinct, many other plants and animals in marine ecosystems will be negatively impacted by this loss, and the environment will be drastically altered. This is also problematic for locals who depend on this resource for food and as a source of income. Conservation efforts have been initiated by an international NGO, the Wildlife Conservation Society (WCS); however, …

Executive Summary, Cumberland County Foodshed Assessment, Report 1, Barbara Ives

Local Food Systems

Like everyone else in these troubled economic times, Mainers are looking for ways to create jobs that will remain relevant and vital in a global economy, that cannot be outsourced, and that will regenerate rather than exploit our natural resources.

A growing number of people believe that a food system rooted in local farms, fisheries, and food production and distribution enterprises can strengthen Maine’s economy and its communities’ health, thereby increasing revenue and decreasing an expense that is crippling government agencies and individuals alike – healthcare. Business people who want to make a living related to food, and public and …

A Five-Year Management Strategy For The Recreational Trout Fishery, Department Of Fisheries Western Australia.

The discussion paper for a five-year management strategy for the recreational trout fishery (Fisheries Management Paper No. 234) was released for public comment in September 2009. It attracted a moderate level of comment with 17 written submissions being received from a variety of stakeholders. The RFFSS considered these submissions and took into account the issues raised in developing the recommendations contained within this paper.

The “Marine Heat Wave” Off Western Australia During The Summer Of 2010/11, Alan Pearce, Gary Jackson, Jenny Moore, Ming Feng, Daniel J. Gaughan

Fisheries Research Reports

Water temperatures off the south-western coast of Western Australia rose to unprecedented levels during February and March 2011, and this warming event has been termed a “marine heat wave”. While surface temperatures were more than 3°C above the long-term monthly average over an extended area in February 2011, the temperature in some localised areas in coastal waters exceeded the long-term monthly average by 5°C for periods of a day or two in late February/early March

Oyster Reefs As Natural Breakwaters Mitigate Shoreline Loss And Facilitate Fisheries, Steven B. Scyphers, Sean P. Powers, Kenneth L. Heck Jr., Dorothy Byron

University Faculty and Staff Publications

Shorelines at the interface of marine, estuarine and terrestrial biomes are among the most degraded and threatened habitats in the coastal zone because of their sensitivity to sea level rise, storms and increased human utilization. Previous efforts to protect shorelines have largely involved constructing bulkheads and seawalls which can detrimentally affect nearshore habitats. Recently, efforts have shifted towards “living shoreline” approaches that include biogenic breakwater reefs. Our study experimentally tested the efficacy of breakwater reefs constructed of oyster shell for protecting eroding coastal shorelines and their effect on nearshore fish and shellfish communities. Along two different stretches of eroding shoreline, …

Rumbling In The Benthos: Acoustic Ecology Of The California Mantis Shrimp Hemisquilla Californiensis, E. Staaterman, C. Clark, A. Gallagher, M. Devries, T. Claverie, S. Patek

Faculty Publications, Biological Sciences

Although much research has focused on acoustic mapping and exploration of the benthic environment, little is known about the acoustic ecology of benthic organisms, particularly benthic crustaceans. Through the use of a coupled audio–video system, a hydrophone array, and an autonomous recording unit, we tested several hypotheses about the field acoustics of a benthic marine crustacean, Hemisquilla califor­niensis. Living in muddy burrows in southern California, these large mantis shrimp produce low frequency ‘rumbles’ through muscle vibrations. First, we tested whether acoustic signals are similar in the field and in the laboratory, and discovered that field-produced rumbles are more acoustically and …

Interspecies Comparison Of Αii-Spectrin Abundance Between Chinook Salmon And Steelhead, Brielle D. Kemis, Ann L. Miracle, Katie A. Wagner, Christa M. Woodley

STAR Program Research Presentations

Salmonids, such as Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss), are a staple economic, recreational, tribal, and environmental resource, yet many populations are unsustainable. This study was part of a broad scale effort to monitor the impact of downstream migration obstacles on juvenile salmonid health and survival, which is an essential step towards increasing Smolt-to-Adult Return ratios (SARs). The objective of this study was to determine if juvenile Chinook salmon and steelhead exhibit differing quantities of alphaII-Spectrin Breakdown Products (SBDPs) over two consecutive spring migration periods, indicative of neurogenesis rate and/or biological response to head …

Assessment Of The Risks Associated With The Release Of Abalone Sourced From Abalone Hatcheries For Enhancement Or Marine Grow-Out In The Open Ocean Areas Of Wa, Brian J. Jones, Warrick Fletcher

Fisheries Research Reports

The virus that causes Abalone Viral Ganglioneuritis (AVG) is considered to be exotic to Western Australia (WA). The known distribution includes Victoria, Tasmania and Taiwan. There are a number of known strains of the virus; Tasmanian strains do not (to date) cause mortalities in wild abalone (but do so in farms and processing facilities). Victorian and Taiwanese strains cause high mortalities in wild abalone. Despite active surveillance, the virus has not been found in NSW, South Australia or Western Australia but there is a low likelihood that WA specific strains may exist undetected.

Pilot Evaluation Of The Efficacy Of Electronic Monitoring On A Demersal Gillnet Vessel As An Alternative To Human Observers, R Evans, Brett Molony

Fisheries Research Reports

A large number of documents exist in peer reviewed and ‘grey’ scientific literature that describe ‘how to’ establish a generic observer program for bycatch. Rather than repeat the many reviews of establishing observer programs, this component of WAMSI project 4.4.1 undertook a pilot trial to test the efficacy of using Electronic Monitoring (EM) in place of on-board human observers to record and identify the catch composition of a commercial demersal gillnet vessel. Approximately 80% of all catch (including target, by-product and bycatch species), including interactions with threatened, endangered and protected species (TEPS) could be identified to the same taxon as …

Fisheries Occasional Publication No.99 - Review Of The Western Australian Rock Lobster Stock Assessment, Andre E. Punt, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In 2000, the West Australian Rock Lobster (WRL) fishery became the first fishery in the world to be certified by the Marine Stewardship Council (MSC). At the annual audit in December 2010, the MSC’s independent certifying body, Scientific Certification Systems, set a number of conditions for ongoing certification. The most important condition under Principle 1, Stock Assessment, was to have an international stock assessment and modelling expert undertake a review of the latest version of the WRL Stock Assessment Report that has been used to provide advice for the management of the fishery, and 2010 stock assessment and 2010/11 management …
