Gammarus sp. : Scud–The Race Rocks taxonomy

Posted on by
From Wikkipedias: Gammarus is an amphipod crustacean genus in the family Gammaridae. It contains more than 200 described species, making it one of the most speciose genera of crustaceans.[2] Different species have different optimal conditions, particularly in terms of salinity, and different tolerances; Gammarus pulex, for instance, is a purely freshwater species, while Gammarus locusta is estuarine, only living where the salinity is greater than 25‰.[3] Species of Gammarus are the typical “scuds” of North America and range widely throughout the Holarctic. A considerable number are also found southwards into the Northern Hemisphere tropics, particularly in Southeast Asia.[4]

  • Marine Protected areas in Canada- Implications for both conservation and fisheries management, C.S Jamieson and C.O.Levings 2001
    Abstract: Legislated marine “protected” areas are now widely distributed throughout tropical and temperate waters, but the nature of human activities actually restricted in any area varies. This ambiguity about what “protected” means hasresulted in contradictory claims as to both the benefits and costs of marine protected areas. Here, we give our perspective on the current status of marine resource protection in Canada in general and British Columbia in particular. We first describe and discuss the history of Canadian marine protected areas established to date. Many areas are claimed to be protected, with little understanding by either the general public or even most marine resource experts as to what human activities are actually regulated by legislative designations. Second, we present an overview of biological reasons and objectives for marine protected areas, followed by a review of both the conservation and fisheries management effects and implications resulting from effective renewable resource protection. Finally, we propose a unique qualitative scheme for classifying and describing marine protected areas of different types to determine relative measures of protection.
  • Marine Protected Areas: An Essential Element of the Fisheries Management Toolbox
    François Côté, Jessica Finney, Science and Technology Division 24 April 2006
    “Introduction :     The urgent need to improve protection and management of marine areas is becoming more and more apparent as the number and status of many important fish stocks continue to deteriorate. It has become evident that the vast majority of attempts to manage fisheries resources in a sustainable fashion have been unsuccessful, and resource managers are beginning to seek alternatives to traditional management strategies. Marine protected areas (MPAs) are viewed as important tools in reducing the risks associated with current fisheries management practices. MPAs are areas of ocean that are protected from various human activities.(1) Canada has taken initial steps to ensure that MPAs will complement existing measures to conserve and protect fisheries resources. In fact, the establishment of a national network of MPAs is one of the main components of the federal oceans management strategy outlined in Part II of the 1997 Oceans Act.(2) By all accounts, however, progress has been slow.This paper provides an overview of some of the background theory behind creating and managing effective MPAs, and looks at how these areas are being used as part of Canada’s oceans and fisheries management strategy. ” Can.

    .XwaYeN (Race Rocks), as Canada’s first Ocean Act MPA, was recommended for designation based on a series of recommendations that were developed through a collaborative process. This process had a numberof distinctive features and quite remarkable results. Was the process based on authority or interests? How do you bring a disparate spectrum of interests together to establish consensus-based recommendations for conservation and protection? As a case study, the XwaYeN experience offered many lessons and has encouraged a wide range of interests to describe their own process and vision for further MPA designations.

    “9.2 Key challenges

    One of the most significant barriers to advancing marine conservation in Canada is the extent to which responsibility for protecting marine habitat is fragmented and spread among various agencies and jurisdictions. Within the federal government alone there are more than 35 pieces of legislation and at least 25 agencies concerned with marine management. In addition, although the federal government has primary jurisdiction over the oceans and the continental shelf, authority for some portions of the coastal zone is shared by the federal government with provinces and territories. This has resulted in confusion, duplication of effort and protracted delays in making decisions that affect ocean users.    There is also a lack of coordination within the federal government. Although Fisheries and Oceans Canada has a mandate under the Oceans Act to coordinate the efforts of the three federal agencies that can establish MPAs—Fisheries and Oceans Canada, Parks Canada and Environment Canada—there is no comprehensive federal approach to MPAs. Fisheries and Oceans Canada has taken a “learning by doing” approach to Oceans Act MPAs, by identifying a series of pilot Oceans Act MPA sites on Canada’s coasts. Parks Canada has developed a systems plan based on 29 marine regions but has not identified specific sites for all of them, and Environment Canada has yet to identify the sites that would complete its marine system of national and marine wildlife areas. The lack of a coordinated national plan for MPAs has led to uncertainty among resource users that in some cases has translated into fear and diminished support for conservation initiatives.A third major challenge is our limited knowledge of the oceans compared with what is known about the land. For example, decision makers have extremely limited knowledge about the seabed and the habitat it provides for key species. In essence, we do not know enough about the underwater topography of important marine habitats to manage them effectively. Much of the bottom of Canada’s oceans is mapped at only a very rough scale and, even though ecosystem management requires an understanding of marine food webs, many of the links between marine species are not well understood. ” end of quote

Report: Marine Reserves Key to Preserving Ocean Ecosystems
(01/14/2003)
In his report prepared for the Pew Oceans Commission, Dr. Stephen Palumbi of Stanford University finds that fully protected marine reserves are an effective tool for restoring and maintaining coastal and marine habitats. Marine Reserves: A Tool for Ecosystem Management and Conservation describes how intensive loss of coastal habitat, pollution, commercial fishing, recreational fishing, and tourism can degrade marine ecosystems, and presents a crucial role for marine reserves in ocean management.

The Rock was Ours! Race Rocks Weekend

“The Rock was ours.” Race Rocks Weekend

article and photos by Jeremias Prassl with group Naja, Angie, Ahmad, Josh, Roberto

It was after a week of painful Mock exams (or Group IV projects…), that we made our way out to Race Rocks on a beautiful Friday afternoon. Mike and Carrol, the light house guardians, had gone to town for the weekend, and so The Rock was ours. Second Nature was packed up high with our bags, food and dive gear as we left Pearson with Garry. The task list for the weekend included digging a trench for a new camera, fulfilling all island duties, and doing underwater camera work during our dives.

Saturday started with a surprise visit: A military Zodiac pulled up the docks, and two commandos informed us that they were looking for “the explosive”.

As we soon figured out, a grey cylinder the Navy had lost off one of their vessels had been washed ashore at Race Rocks – and it was still active! But with their gear, the soldiers took care of it within a few minutes. For the rest of the morning we were busy with digging a trench in the rocky ground – we definitely earned the big lunch that followed. In the afternoon we strolled around the intertidal zone with our learned guide Josh, before we got ready for a dive. We were treated to the usual beauty of the Marine Protected Area underwater, and after our air had run out we went for a snorkelling trip. The day was finished by a chocolate fondue under the constantly turning light on top of the lighthouse.

When Mike and Carrol came back, they brought their grandchildren Mike and Chris, and we took them around for an exploration of the island, including the two female elephant seals lazily in the sun. When Garry came to pick us up after a second dive Sunday afternoon, we would’ve all done a lot to stay longer… for a few more days of our great weekend. A special thanks to Chris and Garry for all their assistance!
