Chief Kerry's moose : a guidebook to land use and occupancy mapping, research design, and data collection

Aboriginal peoples in Canada have been mapping aspects of their cultures for more than a generation. Indians, Inuit, Métis, non-status Indians and others have called their maps by different names at various times and places: land use and occupancy; land occupancy and use; traditional use; traditional land use and occupancy; current use; cultural sensitive areas; and so on. I use “land use and occupancy mapping” in a generic sense to include all the above. The term refers to the collection of interview data about traditional use of resources and occupancy of lands by First Nation persons, and the presentation of those data in map form. Think of it as the geography of oral tradition, or as the mapping of cultural and resource geography. (PDF contains 81 pages.)

Aquatic insects as target organisms for the study of effects of projected climate change in the British Isles

The chief objectives of this brief review are to collate and synthesise quantitative information on the temperature requirements of aquatic insects, and to identify species, and groups of species, that could be useful indicators of climate change and predictors of the ecological effects of change. It arose from the first phase of the Terrestrial Initiative in Global Environmental Research (TIGER), a five-year, NERC Community Programme on the role of the terrestrial biosphere in the science of global change. This phase involved the identification of criteria for selecting species suitable for the study of effects of projected climate change in the British Isles. Field and laboratory studies are reviewed, and criteria for selection of species for future research are suggested. The literature survey shows that no species of aquatic insect can be found to meet all three criteria, but information on the British stoneflies and their eggs already satisfies two of them.

Seasonal variation in the diurnal periodicity of activity of the perch, Perca fluviatilis L. [Translation from: Kalamies 1973(3) 3.]

The most common catch of the amateur angler is the perch and it is the diurnal periodicity of activity (& catchability) which is examined in this study based on earlier articles and manuscripts by the authors. Of all environmental factors, variation in light and temperature are the chief reasons in establishing the times of activity periods. Winter, summer and autumn activity was studied. The spawning perch was found to be more active than the non-spawning perch. The time of day in which the fish may be active is dependant on its ability to sense changes in the external environment. Its adaptation to light is the reason for day-activity in the winter, and also accounts for the fact that hardly any activity occurs between sunset and sunrise when this period exceeds 6 hours.

Water chemistry and osmoregulation in some arthropods, especially Malacostraca

This article briefly summarises some chief characteristics of osmoregulatory systems in malacostracan crustaceans, evolved to combat hydration, and the limitations thereby imposed on the salinity tolerance and distribution of these animals.

The Atlantic and Gulf Menhaden Purse Seine Fisheries: Origins, Harvesting Technologies, Biostatistical Monitoring, Recent Trends in Fisheries Statistics, and Forecasting

With its genesis in New England during the 1800's, the purse seine fishery for Atlantic menhaden, Brevoortia tyrannus, expanded south and by the early 1900's ranged the length of the eastern seaboard. The purse seine fishery for Gulf menhaden. B. patronus, is of relatively recent development, exploitation of the stock beginning in the late 1940's. Landings from both fisheries annually comprise 35-40% of the total U. S. fisheries landings, ranking menhaden first in terms of volume landed. Technological advances in harvesting methods, fish-spotting capabilities, and vessel designs accelerated after World War II, resulting in larger, faster, and wider-ranging carrier vessels, improved speed and efficiency of the harvest, and reduction in labor requirements. Chief products of the menhaden industry are fish meal, fish oil, and solubles, but research into new product lines is underway. Since 1955 on the Atlantic coast and 1964 on the Gulf coast, the NMFS has monitored the fisheries for biostatistical data. Annual data summaries of numbers-of-fish-at-age harvested, catch tonnage, and fishing effort of the fleet form the basis of routine stock assessments and annual catch forecasts to industry for the upcoming fishing season. After landings declined in the 1960's, the Atlantic menhaden stock has recovered through the 1970's and 1980's. Exceptional year classes of Gulf menhaden in recent years account for record landings during the 1980's.

Salmon stocks and fisheries in England and Wales, 2001. Preliminary assessment prepared for ICES, April 2002

This report presents a preliminary assessment of the state of salmon stocks and fisheries in England and Wales in 2001 to assist ICES in providing scientific advice to NASCO and to provide early feedback to fishery managers and anglers. The chief indicators of the state o f salmon stocks are normally the catches taken by rod and net fisheries. However, in 2001 angling was affected by the outbreak of foot and mouth disease (FMD), which restricted angling opportunities and access to rod fisheries in many parts of the country for lengthy periods. It is impossible to quantify the impact that FMD had on rod catches, although these were undoubtedly significantly reduced; net fisheries were unaffected by FMD. The declared salmon catch for 2001 (including those fish released alive by anglers) is provisionally estimated at 209 tonnes, representing some 57,000 fish, and comprising 153 tonnes (-43,000 fish) by nets and fixed engines and 56 tonnes (-14,000 fish) by rods. For direct comparison with previous years, it should be noted that the declared catch prior to the issue of a second reminder was about 49 tonnes (see below). An estimated 26 tonnes (43%) of the rod catch was released alive. These figures do not take account of catches of salmon which go unreported (including those taken illegally), and it is estimated that there may have been a total of 33 tonnes of additional fish caught in 2001; approximately 15% of all fish killed.

Some observations on the problem of marine timber destroying organisms of Indian coasts

In India the chief marine timber boring organisms are 2 species of Martesia, 28 species of shipworms, 4 species and a variety of Sphaeroma and 9 species of Limnoria besides bacteria and fungi. The occurrence, abundance and activity of the various species of borers show remarkable variations and fluctuations in the different harbours of India, each harbour or area having its own dominant set of species and an assemblage of less important forms. These species have their own characteristic preferences, life history and seasons of attachment and a scheme evolved for one locality may prove ineffective for another. Through a delicate and complex ecological adjustment the borers occurring in a locality have reached an interrelationship reducing interspecific and intraspecific competition. The seasons of settlement of the dominant borers in the different harbours of India are indicated. The need for a detailed biological enquiry is stressed.

A survey of the quality of salt cured fish produced in the Kanyakumari Disrict [i.e. District], Madras State

A survey of the quality of salt cured fish in Kanyakumari District, Madras State was done during the years 1963 and 1964 to obtain necessary basic information to formulate quality standards for these products which are gaining importance in the export trade. 155 trade samples of sun-dried, dry-salted, wet-cured and pit-cured fishery products were examined for their chemical quality and organoleptic characteristics. 26.5% of the sun-dried products, 25% of the wet cured fish, 55.21% of the dried salted products and none of the pit cured samples were found to be good in quality. The sun dried products were generally found to have heavy admixture of sand and were inadequately dried. The chief defects in the salt cured fish products were found to be the use of spoiled fish, imperfect cleaning and washing, use of impure salt, inadequate salting, curing and drying, and unhygienic conditions in all stages. Quality standards must be formulated for each variety of salt cured fish product and adequate measures taken to rectify the defects and enforce the quality standards.

A Preliminary survey of 21 Ceylon lakes. 1. Fisheries of two lakes, Parakrama Samudra and Minneriya Wewa

Fourteen species of indigenous fish and three species of introduced fish commonly used for food are present in Parakrama Samudra and Minneriya Wewa. Commercial fishing is done throughout the year in these two lakes by gill nets, shore-seines ("Ma-del" nets) and cast nets. From records of fish landings maintained from 1957 it is seen that the production of fish at Parakrama Samudra has increased from 41 pounds per acre per annum in 1957 to 117 pounds per acre per annum in 1962 and at Minneriya Wewa from 11 pounds per acre per annum in 1957 to 118 pounds per acre per annum in 1962. Tilapia mossambica formed the chief constituent of the catch at both these lakes and it was due to this fish that the commercial fisheries at both these places were successful. It is recommended that fishing effort be further increased in both these lakes and records be kept to note any tendency towards over-exploitation.

Fisheries annual report for the year ending 1966

The Chief Fisheries Officer's Annual Report of 1965 showed then that there had been an increase in the volume of work of the Fisheries Department. This increase continued and accelerated during 1966. The Transitional Development Plan was successfully completed on schedule, with the exception of two items which had been almost finished by the end of the year, and the Four Year Development Plan was introduced; by the end of the year all officers of the Department were fully engaged in its implementation.

East African Freshwater Fisheries Research Organization Annual Report 1967

Throughout the year the Fisheries Departments of Tanzania and Uganda continued to forward to EAFFRO data on the commercial fisheries of the lake. Regular records of commercial fishing activity In Kenya waters have not been received, appropriate information has been made available on request from the Chief Fisheries Officer. None of the research staff at EAFFRO have been assigned to a detail ed survey of the statistica1 data available, although severa1 research officers have taken the opportunity of analysing the data appropriate to their own research programmes. As recorded in the last Annual Report, an important feature of the UNDP Lake Victoria Fisheries Research Project will be to undertake the relevant statistical surveys essential to the proper.

The ecology of spiny lobsters, Panulirus spp., of Ceylon waters

Six species of spiny lobsters of the genus Panulirus have been recorded in Ceylon waters. It is clear, therefore, that species dominance and ecological separation in the genus Panulirus is demonstrable and that the separation is dependent on the particular ecological preferences of the different species. In order to determine the factors governing the ecological separation, it was decided to make a detailed study of the environments in which the different species were found. Diving operations constituted the chief method of investigation. However, information was also obtained from commercial skin-divers, trap fishermen, bottom-set net fishermen and trawling operations. The period of investigations extended from 1962-1968.

A survey of research and scientific services in East Africa, 1947-56

This "Survey of Research and Scientific Services in East Arica 1947-1956" has been prepared by Dr. E. B. Worthington, who held the post of Scientific Secretary in the Office of the Chief Secretary to the East African Governor's Conference and subsequently in the Administrator's Office of the East Mrica High Commission during the period January, 1947-May, 1951. Dr. Worthington is now Secretary General of the Scientific Council for, Arica South of the Sahara

East African Freshwater Fisheries Research Organization Annual Report 1965

Throughout the year the Fisheries Departments of Tanzania and Uganda continued to forward to EAFFRO data on the commercial fisheries of Lake Victoria, particularly statistics of fishing-effort and fish-landings. The Kenya Fisheries Department was re-established at Kisumu towards the end of 1964 and has expanded its activities during 1965; whilst regular records of commercial fishing activity have not been despatched to Jinja, appropriate information has been made available on request from the Chief Fisheries Officer. None of the existing research officers at EAFFRO have been assigned to a detailed survey of the statistical data available, although several officers have taken the opportunity of analysing the data regarding the species considered under their own research programmes. As recorded in the last Annual Report, one important function of the UNDP Lake Victoria Fisheries Research Project will be to undertake the relevant statistical surveys essential to the proper management of the commercial fisheries of Lake Victoria. The level of the lake remained abnormally high but fluctuated somewhat during the year, reaching a maximum in May, but falling to a minimum in October before beginning to rise again with the rains at the end of the twelve-month period. The maximum figure for the year recorded at Jinja: 12.92 ft. above datum did not reach the peak recorded in 1964: 13.33 ft. above datum, which was the maximum reading taken since records were begun in 1899. Scientific work carried out by the organization during the year 1965 included work on the following: Commercial fisheries of Lake Victoria Nile Perch investigations Fisheries surveys in Kenya and Tanzania Studies on anadromous fishes Studies on mormyrid fishes Studies on Tilapia species Studies on Alestes Studies on Haplochromis species
