A 139-year dendroclimatic cycle, cultural/environmental history, sunspots, and longer-term cycles

Higher resolution time-stratigraphic records suggest correlation of lower frequency paleoclimatic events with Milankovitch obliquity/precessional cycles and of higher frequency events with the evidently resonance-related Pettersson maximum tidal force (MTF) model. Subsequently published records, mainly pollen, seemingly confirm that atmospheric resonances may have modulated past climatic changes in phase with average MTF cycles of 1668, 1112, and 556 years, as calculated in anomalistic years from planetary movements by Stacey. Stacey accepts Pettersson's dating of AD 1433 (517 YBP) for the last major perihelian spring tide based solely on calculations of moon- and earth-orbital relations to the sun. Use of AD 1433 as an origin for the tidal resonance model seemingly continues to provide a best fit for the timing of cyclical patterns in the presented paleoclimate time series.

A 10-year time series of zooplankton anomalies off the British Columbia coast [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Zooplankton biomass and species composition have been sampled since 1985 at a set of standard locations off Vancouver Island. From these data, I have estimated multi-year average seasonal cycles and time series of anomalies from these averages.

Physical, chemical, and biological characterization of water year types in the San Francisco Bay estuary [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Twenty-three years of physical, chemical, and biological data were used to characterize conditions associated with wet, normal, dry, and critical water year types in the upper San Francisco Bay estuary.

An 800-year paleoflood record from the Sacramento Valley, California [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Four cores recovered from Little Packer Lake in Glenn County, California, have provided a paleoflood record for the past 800 years. ... The sequence of flood deposits in the top 2 meters of the record shows a reasonable agreement with the known history of floods during the past 150 years. At least three major flood events are indicated for AD 1400-1525, although these dates may have to be revised when more dates become available.

A detailed 2,000-year late-Holocene pollen record from Lower Pahranagat Lake, southern Nevada, USA [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Preliminary analysis of 128 pollen samples and 7 radiocarbon dates from a 5-meter-long, 10-centimeter-diameter sediment core retrieved from Lower Pahranagat Lake (elevation 975 meters), Lincoln County, Nevada, gives us a rare, continuous record of vegetation change at 14-year intervals over the past 2,000 years.

Carp seed production during drought year 1987 under controlled hatchery system

The introduction of the controlled hatchery system "Model CIFE D-81" resulted in a production of 60 lakhs Indian major carp seed in the drought area of eastern Uttar Pradesh. The hatchery system provided optimum temperature, dissolved oxygen and pH for breeding and hatching and also removed the metabolites generated. The technology is simple and the success of the program attracts pisciculturists.

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 Inland Fisheries Research Organization Annual Report for the year 1948

Introduction The laboratory at Jinja is being developed as a centre for hydro-biological research in East Africa, It has been built and is at present wholly financed from a grant from the Central Research allocation of the Colonial Development Fund. The building contains six laboratories in addition to a library, common room and general office. A maximum number of ten research workers could be given laboratory accommodation. However, shortage of living accommodation will limit the numbers who can work here for the next year or two.

East African Inland Fisheries Research Organization Annual Report for year ended 31st December 1949

The present work is now concentrated mainly on the Tilapia fishery. As a result of past experience it is easier to direct efforts in a way likely to give useful results. Work on the Tilapia is now beyond the purely exploratory stage and these fishing experiments are being carried but in areas which are known to contain large numbers of Tilapia. Nets of different mesh size are being used in order to catch all stages of these fish. These nets are being fished at the surface and at the bottom, close to the shore and further out. The data collected should provide more precise information regarding the periodic migration, both vertical and horizontal, of these fish, a better understanding of their life history and breeding habits, and indicate' the potential possibilities of this fishery. These data should explain the variation in numbers of fish caught by Africans during different months of the year; they should also make it possible to determine more exactly the best type of net for use in this particular fishery.

Year-round and rotational freshwater prawn, Macrobrachium rosenbergii and paddy farming: soil quality, production and economics

A study was carried out at five upazillas (Dumuria, Fakirhat, Pirojpur sadar, Gopalgonj sadar and Kalia) of five southern districts of Khulna, Bagerhat, Pirojpur, Gopalgonj and Narail to understand the comparative production performance and any effect on soil quality in case of year-round golda (Macrobrachium rosenbergii), alternate prawn-paddy and year-round paddy farming. A direct interview of 55 farmers was taken, using pretested questionnaire, and soil samples were taken from selected farms before and after each crop. Among the five upazillas, farmers in Gopalgonj sadar and Kalia are not practicing year-round golda. Rotational golda-paddy farming has been recorded to result in maximum profit, with the highest of Tk. 310,912/ha/year in 2003 at Dumuria. Only paddy farming is less profitable than other two cropping patterns, irrespective of study sites. The nutrient status of soil in rotational golda and paddy farming has been found improved, compared to that of only golda or paddy farming.

Annual Report of the Fisheries Department for the year ended 31st December, 1971

This Annual report sets out clearly the various activities undertaken by the ministry in the field of fisheries for the period 1971. It has highlighted some commendable achievements for fisheries to claim its place among the rapidly expanding rural industries in this country. Fish production now at 162,000 metric tons per annum worth over 130 million shillings at the lakeshore, is not only a source of food but also a source of employment. It is believed that the fishing industry is at the moment employing more than 35,000 people in the various aspects of the industry, for example, fishing, fish processing, fish marketing and manufacture of fishing equipment. It is, therefore, greatly contributing not only to our nutrition but also to the economic development.
