The Impact Of Extended Jurisdiction To 200 Nautical Miles On The Development And Management Of Fisheries In Western Samoa, Fili Suafoa

Marine Affairs Theses and Major Papers

The consequences of the inevitable acceptance of extended jurisdiction and its impact on the development and management of fisheries in Western Samoa are considered within the framework of the principles outlined at the United Nations Third Conference of the Law of the Sea - Revised Informal Composite Negotiating Text for the Eighth Session 1979. It is pointed out that with the passage of the 200-mile exclusive economic zone, Western Samoa not only has the opportunity to benefit from the harvesting of fish under its jurisdiction, but also must accept the responsibility of ensuring that the resource is rationally managed, and …

The Feasibility Of Processing Fish Aboard The F/V Friesland, Thomas Dykstra

Marine Affairs Theses and Major Papers

Many social, economic and regulatory changes have been occurring in the New England fishing industry over the past few years. These changes demand responses from the individual industry participants. The purpose of this paper is to look at the feasibility of processing onboard the F/V Friesland, as an individual response, in an effort to increase the ex-vessel price of fish resulting in the maintenance of a gross stock and a life style. The F/V Friesland, built in 1978, is an 87 foot stern trawler which participates in the mixed species groundfshery of New England out of the port of Pt. …

Experimental Summaries - Plant Research

Effect of stubble and seed infection on S. nodorum at Badgingarra. Fungicide timing on Septoria control.

Double cropping wheat was simulated by spreading stubble fragments collected from an adjoining paddock at 30 g/m2. Infected seed was from a 1979 sowing at Badgingarra, clean seed was pedigree Gamenya ex Merredin. Treatments were thus:- 1. Clean seed, no stubble. 2. Clean seed plus stubble. 3. Infected seed, no stubble. 4. Infected seed plus stubble. Plots were 10 x 25 m separated by equal sized barley buffers.

Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant

Experimental Summaries - Plant Research

Influence of planting system on surface soil, physical conditions and soil water relations. The availability of soil water for crop use can this way be influenced by planting system. Various aspects of soil water relations were examined in varying detail at three sites - Wongan Hills, Avondale and Merredin, over the 1979 and 1980 growing seasons. Some of this soil water data are presented here. The Department of Agriculture initiated a programme in 1977 to investigate and compare crop performance under several planting systems. This project was part of this programme and had as its objectives: 1. Measurement of soil …

The Relationship Of Food Conversion Efficiency And Growth Potential In Juvenile Mosquitofish, Gambusia Affinis, Joseph J. Cech Jr., Michael J. Massingill, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

New information concerning respiratory metabolic rates of juvenile mosquitofish (i = 915 mg 02 kg-1 h-1 at 20° C) was applied to existing data on mosquitofish respiration and combined with findings on growth and food consumption rates to determine percentages of net ingested energy used for growth and respiration over a 10- 35° C temperature range. The energy percentage used by mosquitofish for respiration was minimized at 25-30° C while that used for growth (= food conversion efficiency) was maximized at the same temperature. A calculated growth potential index, derived from an overall energy balance equation, was also maximized at …

Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne

KWRRI Research Reports

Aquatic toxicity tests were conducted with atrazine, carbon tetrachloride, chloroform, methylene chloride, trisodium nitrilotriacetic acid (NTA), and phenol. Each compound was administered to developmental stages of three to five amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. Test responses included lethality and teratogenesis. Different amphibian species exhibited varying degrees of tolerance to the selected compounds. Greatest tolerance usually was observed for the more broadly adapted semi-aquatic and terrestrial species (e.g., Bufo americanus, Bufo fowleri). The more sensitive amphibians usually included those species which normally are restricted to aquatic or moist habitats (e.g., Rana …

Aspects Of Larval Ecology Of Squilla Empusa (Crustacea, Stomatopoda) In Chesapeake Bay, Steven G. Morgan

OES Faculty Publications

Larvae of Squilla empusa were collected from the plankton and were laboratory-reared in 16 combinations of temperature and salinity to determine their tolerances. Larvae survived longer and molted more frequently when reared at 25%, and 20° or 25° C, which corresponds to the natural conditions of Chesapeake Bay when the larvae were collected.

A 2 year planktonic survey conducted in the lower region of the bay by the Virginia Institute of Marine Sciences was compared with a survey made at the bay mouth in 1976. The seasonal occurrence of Squilla empusa larvae extended from the last week of July until …
