The paper develops a model of recreational fisher behaviour in which
fishers maximize their individual utility by adjusting fishing time, trips,
catch and size of fish caught. It investigates the optimal behaviour or an
individual fisher with and without constraints such as bag limits. The
model is used to assess...
The West Coast Demersal fishery in Western Australia includes some
highly prized recreational fish: dhufish, pink snapper and baldchin groper.
Following a recent assessment that found these stocks are under threat from
overfishing, a range of new regulations designed to restrict effort have been
introduced with the objective to facilitate...
In the standard economic approach to optimal allocation, aggregate
economic benefit is maximised where the sustainable harvest is allocated
so that marginal net benefits are equal. The model assumes a known
sustainable harvest. It also assumes optimal intrasectoral allocation in each
sector. The Western Australian West Coast demersal fishery, like...
The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...
The relationship of intracellular drug levels and resultant drug activity to intracellular pH (pHi) was studied in the experimental tumors. Glucose (5 g/kg) and/or sodium oxamate (0.1 mmol) were administered to Walker 256 ascites cells and Ehrlich ascites cells, in an attempt to alter pHi as measured by the distribution...
Pallidosis is a disease of strawberry identified in 1957 with an unknown etiology. Two previously uncharacterized viruses in strawberry, Strawberry pallidosis associated virus (SPaV) and Beet pseudo-yellows virus (BPYV), have been found associated with disease symptoms. The complete nucleotide sequence of both viruses was determined and molecular detection protocols developed....
Male Sprague Dawley rats received a single intraperitoneal dose
of BCNU in experiments designed to measure biochemical changes associated with the pulmonary toxicity described for this agent. Changes in
serum and lung lavage angiotensin converting enzyme (ACE) activity
were measured to detect changes in pulmonary endothelial cell integrity. Alpha-1-proteinase inhibitor...
A study was done on the zoogeography of species of oceanic
shrimp in the North Pacific from 22°N to 56°N and from 124°W to
145°E, using samples of shrimp collected from 1954 to 1969. These
collections were made during the following cruises: John R. Manning
Cruise 22, and the Hugh...
