Spreading Holiday Spirit And Northwestern Salamanders, Ambystoma Gracile (Baird 1859) (Caudata: Ambystomatidae), Across The Usa, Michael R. Rochford, Jeffrey M. Lemm, Kenneth Krysko, Louis A. Somma, Robert W. Hansen, Frank J. Mazzotti

Papers in Herpetology

Introduced species of amphibians and reptiles are of growing conservation concern (Bury and Luckenbach 1976; Krysko et al. 2011; Meshaka 2011). Unintentional introductions result largely from individuals escaping from enclosures or hitch-hiking in cargo or on vehicles, whereas intentional introductions occur primarily because a species is perceived to be of value to humans or from deliberately releasing sick or unwanted animals, including pets (Kraus 2009; Krysko et al. 2011). In Florida, most known introductions are directly related to the pet trade, but about 12% are related to the cargo pathway (Krysko et al. 2011). In this paper, we report the …

Cpue Standardization And Catch Estimate Of Blue Shark By Taiwanese Large-Scale Tuna Longline Fishery In The North Pacific Ocean, Wen-Pei Tsai, Chi-Lu Sun, Kwang-Ming Liu, Shyh-Bin Wang, Nancy C. H. Lo

Journal of Marine Science and Technology–Taiwan

The blue shark, Prionace glauca, is a pelagic species with a circum-global distribution in tropical to temperate waters. It is the top by-catch shark species for the Taiwanese large-scale tuna longline (LTLL) fishery. However, its population status in the North Pacific Ocean is still little known. In the present study, the blue shark catch and effort data from observers' records of Taiwanese LTLL fishing vessels operating in the North Pacific Ocean from 2004 to 2012 were analyzed. Due to the large percentage of zero blue shark catch, the catch per unit effort (CPUE) of blue shark, as the number of …

Shark Bay Prawn Managed Fishery, M. I. Kangas, E. C. Sporer, S. A. Hesp, K. L. Travaille, S. J. Brand-Gardner, P. Cavalli, A. V. Harry

WA Marine Stewardship Council report series

This report provides a comprehensive description of the Shark Bay Prawn Managed Fishery (SBPMF) and contains information relevant to assist the assessment of this fishery against the Marine Stewardship Council (MSC) standard (v1.3) for sustainable fishing. The SBPMF is located in Shark Bay, Western Australia and uses demersal otter trawl gear to predominantly target brown tiger prawns (Penaeus esculentus) and western king prawns (Penaeus latisulcatus).

Effectiveness Of Mitigation Measures To Reduce Interactions Between Commercial Fishing Gear And Whales, Jason R. How, D Coughran, J Smith, M Double, J Harrison, J Mcmath, B Hebiton, Ainslie Maree Denham

Fisheries Research Reports

Effectiveness of mitigation measures to reduce interactions between commercial fishing gear and whales.

Objectives:

1. Start to collect additional information required to determine the spatial and temporal extent of migrating whales and how this overlaps with commercial fishing gear.

2. Examine the effectiveness of potential gear modifications to the float rigs of fishing pots/traps to reduce their likelihood of entangling whales.

Shark Bay Crab Managed Fishery Draft Management Plan 2015, Western Australia. Dept. Of Fisheries

Fisheries Management Papers

The Shark Bay blue swimmer crab resource is harvested commercially by the Shark Bay crab trap, Shark Bay prawn trawl and Shark Bay scallop trawl sectors. The resource also supports a small recreational fishery of about 1 tonne per year.

Selective Impact Of Disease On Coral Communities: Outbreak Of White Syndrome Causes Significant Total Mortality Of Acropora Plate Corals, Jean-Paul A. Hobbs, Ashley J. Frisch, Stephen J. Newman, Corey B. Wakefield

Fisheries Research Articles

Coral diseases represent a significant and increasing threat to coral reefs. Among the most destructive diseases is White Syndrome (WS), which is increasing in distribution and prevalence throughout the Indo-Pacific. The aim of this study was to determine taxonomic and spatial patterns in mortality rates of corals following the 2008 outbreak of WS at Christmas Island in the eastern Indian Ocean. WS mainly affected Acropora plate corals and caused total mortality of 36% of colonies across all surveyed sites and depths. Total mortality varied between sites but was generally much greater in the shallows (0–96% of colonies at 5 m …

Seasonal Wind Patterns Around The Western Australian Coastline And Their Application In Fisheries Analysis, Alan Pearce, Anthony M. Hart, D. V. Murphy, Hannah Rice

Fisheries Research Reports

Monthly wind statistics have been derived for 23 weather stations along the Western Australian coast from Wyndham in the north-east of the state, down the west coast and around to Eucla in the south-east. The overall seasonal wind cycle at each site has been derived based on the 30-year period 1982 to 2011 (although a few stations had shorter records), and these show the major changes between the wind regimes along the Northwest Shelf, the west coast and the south coast.

Interdisciplinary Modeling For Water-Related Issues Graduate Course, Laurel Saito, Alexander Fernald, Timothy Link

All ECSTATIC Materials

The science and management of aquatic ecosystems is inherently interdisciplinary, with issues associated with hydrology, atmospheric science, water quality, geochemistry, sociology, economics, environmental science, and ecology. Addressing water resources issues in any one discipline invariably involves effects that concern other disciplines, and attempts to address one issue often have consequences that exacerbate existing issues or concerns, or create new ones (Jørgensen et al. 1992; Lackey et al. 1975; Straskraba 1994) due to the strongly interactive nature of key processes (Christensen et al. 1996). Thus, research and management of aquatic ecosystems must be interdisciplinary to be most effective, but such truly …

Fisheries Research Report No. 263: Development Of Octopus Aquaculture - Rearing, Handling And Systems Design For Octopus Tetricus Commercial Aquaculture Frdc Project No 2009/206, Sagiv Kolkovski, R Cammilleri, Justin King, Nicole Watts, M Natale, Adva Mori

Fisheries Research Reports

The following document ‘Development of octopus aquaculture, rearing, handling and systems designs for Octopus tetricus commercial aquaculture’ contains protocols developed during the FRDC project 2009/206. These protocols encompass the most up-to-date rearing, handling and systems designs for Octopus tetricus commercial aquaculture. These protocols are the result of extensive research and development work carried out over the past four years by the Department of Fisheries, Western Australia and summarised in the final project report.

Grey (Halichoerus Grypus) And Harbor Seal (Phoca Vitulina) Bycatch And Depredation In New England Sink-Gillnet Fisheries, Laura N. Sirak

All Theses And Dissertations

Marine mammals interact with commercial fisheries via competition for resources, depredation (feeding on fish caught in gear), entanglement, and bycatch in fishing gear. In New England, gray seals (Halichoerus grypus) and harbor seals (Phoca vitulina) are often taken as bycatch in sink-gillnet fisheries and are believed to depredate fish in gillnets. As seal populations increase, interactions with fisheries are also likely to increase, affecting both seal stocks and the New England fishing industry. This study aims to understand seal bycatch in the New England sink-gillnet fisheries by identifying the spatial and temporal trends in bycatch as …

Mate Choice In Temperate And Tropical Spiny Lobsters With Contrasting Reproductive Systems, Mark Butler Iv, Rodney Bertelsen, Alison Macdiarmid

Biological Sciences Faculty Publications

Sperm limitation of reproductive success is common in decapod crustaceans, favouring mating systems in which females compete for large males of high reproductive value. We investigated these phenomena in two species of spiny lobsters—one temperate, one tropical—with contrasting reproductive systems: the Southern Rock Lobster (Jasus edwardsii) and the Caribbean Spiny Lobster (Panulirus argus). We hypothesized that female mate selection should be more pronounced in the temperate J. edwardsii than in the tropical P. argus because J. edwardsii matures later, has a shorter mating season, and produces just one clutch of eggs per year that benefit from …
