The first of January, 1912, E. A. Goldman, of the Biological Survey, Department of Agriculture, was again detailed on the Smithsonian Biological Survey of the Canal Zone. He returned to Panama in January and remained there until the last of June passing most of this period in collecting birds and mammals on the slopes of Mount Pirri on the Pacific side of eastern Panama, near the Colombian border...(Document contains 27 pages)

During the early part of the present year I was again detailed from the Biological Survey, U. S. Department of Agriculture to field work in connection with the Smithsonian Biological Survey of the Panama Canal Zone. Additional collections of mammals and birds were made in January and February in the Canal Zone. From the latter part of February to near the end of June work was carried on in eastern Panama to determine the faunal relation of the region to the Canal Zone and the better known areas to the westward and northward. The work was centered in the Pirri range of mountains which rises to a height of over 5,000 feet near the Colombian boundary southeast of San Miguel Bay...(Document contains 20 pages)

The Channel Islands—sometimes called the Galapagos of North America—are known for their great beauty, rich biodiversity, cultural heritage, and recreational opportunities. In 1980, in recognition of the islands’ importance, the United States Congress established a national park encompassing 5 of California’s Channel Islands (Santa Barbara, Anacapa, Santa Cruz, Santa Rosa, and San Miguel Islands) and waters within 1 nautical mile of the islands. In the same year, Congress declared a national marine sanctuary around each of these islands, including waters up to 6 nautical miles offshore. Approximately 60,000 people visit the Channel Islands each year for aquatic recreation such as fishing, sailing, kayaking, wildlife watching, surfing, and diving. Another 30,000 people visit the islands for hiking, camping, and sightseeing. Dozens of commercial fishing boats based in Santa Barbara, Ventura, Oxnard, and other ports go to the Channel Islands to catch squid, spiny lobster, sea urchin, rockfish, crab, sheephead, flatfish, and sea cucumber, among other species. In the past few decades, advances in fishing technology and the rising number of fishermen, in conjunction with changing ocean conditions and diseases, have contributed to declines in some marine fishes and invertebrates at the Channel Islands. In 1998, citizens from Santa Barbara and Ventura proposed establishment of no-take marine reserves at the Channel Islands, beginning a 4-year process of public meetings, discussions, and scientific analyses. In 2003, the California Fish and Game Commission designated a network of marine protected areas (MPAs) in state waters around the northern Channel Islands. In 2006 and 2007, the National Oceanic and Atmospheric Administration (NOAA) extended the MPAs into the national marine sanctuary’s deeper, federal waters. To determine if the MPAs are protecting marine species and habitats, scientists are monitoring ecological changes. They are studying changes in habitats; abundance and size of species of interest; the ocean food web and ecosystem; and movement of fish and invertebrates from MPAs to surrounding waters. Additionally, scientists are monitoring human activities such as commercial and recreational fisheries, and compliance with MPA regulations. This booklet describes some results from the first 5 years of monitoring the Channel Islands MPAs. Although 5 years is not long enough to determine if the MPAs will accomplish all of their goals, this booklet offers a glimpse of the changes that are beginning to take place and illustrates the types of information that will eventually be used to assess the MPAs’ effectiveness.

In response to a growing body of research on projected climate change impacts to Washington State’s coastal areas, the Washington State Department of Natural Resources’ (DNR) Aquatic Resources Program (the Program) initiated a climate change preparedness effort in 2009 via the development of a Climate Change Adaptation Strategy (the Strategy)i. The Strategy answers the question “What are the next steps that the Program can take to begin preparing for and adapting to climate change impacts in Washington’s coastal areas?” by considering how projected climate change impacts may effect: (1) Washington’s state-owned aquatic landsii, (2) the Program’s management activities, and (3) DNR’s statutorily established guidelines for managing Washington’s state-owned aquatic lands for the benefit of the public. The Program manages Washington’s state-owned aquatic lands according to the guidelines set forth in Revised Code of Washington 79-105-030, which stipulates that DNR must manage state-owned aquatic lands in a manner which provides a balance of the following public benefits: (1) Encouraging direct public uses and access; (2) Fostering water-dependent uses; (3) Ensuring environmental protection; (4) Utilizing renewable resources. (RCW 79-105-030) The law also stipulates that generating revenue in a manner consistent with these four benefits is a public benefit (RCW 79-105-030). Many of the next steps identified in the Strategy build off of recommendations provided by earlier climate change preparation and adaptation efforts in Washington State, most notably those provided by the Preparation and Adaptation Working Group, which were convened by Washington State Executive Order 70-02 in 2007, and those made in the Washington Climate Change Impacts Assessment (Climate Impacts Group, 2009).

From research carried, out on a section of the Levriere, concretions (granules, nodules, which were sometimes joined together) partly covering the river ”bottom” were observed. The authors propose to make besides a petrographic examination of the calcareous precipitations and to see if their origin is connected to a biological activity, or if it is purely a case of a physical-chemical precipitation. The hydrological background of the Levriere, a small river of the Normandy Vexin, is given and conditions of the formation of the concretions studied.

This report looks at the interests of the Fisheries Department for the Lancashire River Board, focusing on the Liverpool and Leeds Canal Survey. It looks at finding parasites in fish from an electrofishing survey (roach and perch). This was to contribute towards the main survey with a possible view to suggesting whether or not the parasites were one reason for the poor fish population. Methods of finding parasites are given, and results of what parasites that were found in the fish are discussed.

This is the report on the Leven estuary project: Fisheries Department final report produced by the Environment Agency North West in 1997. This report contains information about Leven estuary, river Leven catchment, river Crake catchment and the Ulverston Discharges. The Leven estuary is characterised by being very shallow, and shares the extremely variable tides and currents that characterize the whole of Morecambe Bay. There was little detailed knowledge of the impact on the Leven estuary, and particularly its fisheries, of the discharges from Ulverston. There has been some concern expressed by the lave netsmen and the general public about the possible harmful effects of the effluents on the biology of the estuary. In the absence of a definite strategy for the protection and management of the estuary was born this project. The project involves water quality monitoring, effluent and estuary toxicity testing, tracking of effluent plumes, and salmonid tagging and tracking. The entire project commenced in June 1995 and was expected to reach a conclusion in March 1997. The information gained from the project was expected to contribute to the creation of a 'mixing zone' for the effluent, and to improve the environmental management of the estuary and protection of its fishery.
