On-Station Production Of Native Speargrass Hay In Western Australia, G L. Krebs, Robert R. Rouda, S P. Van Wyngaarden

Bulletins 4000 -

This report documents the practical and economic feasibility of on-station harvesting and production of speargrass hay and haylage and its subsequent feeding to cattle and sheep in the extensive regions of south-eastern Western Australia. Four hundred and ten bales weighing an average 275 kg were produced from a total harvested area of 40.6 ha in the vicinity of Duck Dam on Kanandah Station. In the lead up to harvesting, seasonal conditions were among the best on record. Half of the bales produced were further processed into haylage. Two feeding trials, involving wethers at Arubiddy and steers at Kanandah, were undertaken …

Tb188: Tow Tank Scale Modeling In The Design Of Tidal Upwellers, John Riley

Technical Bulletins

In February 1999 an ad hoc committee of representatives of Maine’s shellfish aquaculture industry, The University of Maine, and the Maine Sea Grant College Program met to discuss priorities for research to improve the performance of tidally powered shellfish upwellers. Information from this meeting was incorporated into a proposal submitted later in the year to the Maine Aquaculture Innovation Center. The project was funded and work began in January 2000. The project involved engineering analysis, field measurements of shellfish seed properties, and scale-model testing conducted in the university wave/towing tank with the overall goal of optimizing the design of a …

Tb189: The Cost Of Producing Milk In Maine: Results From The 2002 Dairy Cost Of Production Survey, Timothy J. Dalton, Lisa A. Bragg

Technical Bulletins

This report summarizes the results of the 2002 Dairy Cost of Production survey implemented by The University of Maine and the Maine Milk Commission. Funding for this report was provided by the Maine Milk Commission. Analysis and discussion of the data in this report centers on four major groups called clusters. Cluster analysis attempts to identify groups of farms from within the sample of survey respondents that have relatively homogenous characteristics.

Dam Design For Pastoral Stock Water Supplies, J S. Addison, R J. Law, G B. Eliot

Bulletins 4000 -

These notes provide information on many components of water harvesting storage systems designed for use in semi-arid areas. The notion of a water harvesting and storage system is deliberately emphasised. No single design component can be considered in isolation if the goal of a drought-proof water supply is to be achieved.

A drought-proof surface water supply is achieved by integrating the many design components of a water harvesting/storage system into a practical plan.

Tradeable Property Rights And Overcapacity: The Case Of The Fishery, Dale Squires, Yongil Jeon, R. Quentin Grafton, James E. Kirkley

VIMS Books and Book Chapters

In fisheries, overcapacity is a critical problem that reduces rents and jeopardizes the sustainability of stocks. Using data from the British Columbia (BC) halibut fishery, before and after tradeable property rights were adopted in the harvesting sector, the paper tests for the effects of private rights on capacity and capacity utilization. The results indicate that tradeable property rights can be effective, even in the short-term, at reducing capacity per vessel per day and provide incentives to help overcome the "Tragedy of the Commons".

Capacity And Capacity Utilization In Fishing Industries, James E. Kirkley, Dale Squires

VIMS Books and Book Chapters

The definition and measurement of capacity in fishing and other natural resource industries possess unique problems because of the stock-flow production technology, in which inputs are applied to the natural resource stock to produce a flow of output. In addition, there are often multiple resource stocks, corresponding to different species, with a mobile stock of capital that can exploit one or more of these stocks. In turn, this leads to three unique issues: (1) multiple stocks of capital and the resource; (2) that of aggregation or how to define the industry and resource stocks to consider; and (3), that of …

Measures Of Capacity In A Multispecies Danish Fishery, Neils Vestergaard, Dale Squires, James E. Kirkley

VIMS Books and Book Chapters

Different measures of capacity utilization (CU) are applied to the Danish Gillnet fleet using the Data Envelopment Analysis (DEA) approach. The potential capacity output is found using the output-orientated measure. The CU measures are the partial capacity utilization measure and the Ray measure (DEA measure). The average CU of the Danish Gillnet fleet was found to be between 0.85 and 0.95 depending on the measure used. Since the Danish Gillnet fleet participates in a multispecies fishery regulated by TACs (output) the excess capacity was also found for each species. The results show higher excess capacity for cod and sole than …

Capacity And Offshore Fisheries Development: The Malaysian Purse Seine Fishery, James E. Kirkley, Dale Squires, Mohammad Ferdous Alam, Ishak Haji Omar

VIMS Books and Book Chapters

Many developing countries pursue offshore fisheries development strategies to increase protein supply, expand employment, earn foreign exchange, and militate the conflict between large- and small-scale fisheries over the inshore resource stocks. This study evaluates the economic success of Peninsular Malaysia's offshore fisheries development policy for the west coast purse seine fleet, finding it has largely succeeded on economic grounds

Assessing Capacity And Capacity Utilization In Fisheries When Data Are Limited, James E. Kirkley, Rolf Fare, Shawna Grosskopf, Kenneth Mcconnell, Dale E. Squires, Ivar Strand

VIMS Books and Book Chapters

Excess capacity is globally recognized by resource managers as a major problem for fisheries. Yet, the concept of capacity remains vague, ill-defined, and often ambiguous. Presently, measuring capacity and capacity utilization in fisheries has become more important or of greater public concern than ever because of various national and international agreements or policies to reduce capacity in fisheries throughout the world. In this study, we propose data envelopment analysis (DEA) as one method that may be used to calculate a production-oriented measure of capacity. We conclude that although the DEA approach is limited and does not provide measures of capacity …
