Individual Transferable Quota (ITQ) management systems are typically introduced to promote better capital utilisation by the fishing fleet and other efficiency gains. ITQ management was introduced in the Tasmanian rock lobster industry in 1998 and led to a range of economic, social and cultural...

The economic value of the Tasmanian rock lobster fishery contributes significantly to the States regional economy. The fishery has recreational and commercial components, the latter generating an estimated $184.5 million p.a. ($65 million directly from landed value) and 1350 full-time-equivalent...

The capacity for the Tasmanian southern rock lobster fishery to support the annual har-vest is a function of both growth of the legal sized stock and also recruitment of new lobsters into the stock. Decline in productivity from both of these processes has result-ed in a decline of the...

Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice they are not a panacea and distribution and equity issues have been raised in many cases. To...

The Tasmanian rock lobster industry has been managed by Individually Transferable Quotas (ITQs) and several input control measures since 1998. In this study, nine years of rock lobster fishing business data were used to categorise the catch and quota ownership traits and examine the response to...

Traders in the financial world are assessed by the amount of money they make and, increasingly, by the amount of money they make per unit of risk taken, a measure known as the Sharpe Ratio. Little is known about the average Sharpe Ratio among traders, but the Efficient Market Hypothesis suggests...

For climate risk management, cumulative distribution functions (CDFs) are an important source of information. They are ideally suited to compare probabilistic forecasts of primary (e.g. rainfall) or secondary data (e.g. crop yields). Summarised as CDFs, such forecasts allow an easy quantitative...

Fisheries scientists and managers want precise estimates of fishing and natural mortality for assessments and management decisions. Because tagging can be an expensive option, maximizing potential benefits requires careful consideration of experimental design. We evaluated four options for...

Determination of exploitation rate is considered important for both stock assessment and establishment of fishery reference points. From 1992 to 1996, a project was undertaken to evaluate the change-in-ratio technique for estimating exploitation rates for male lobsters off southern Tasmania....

In this paper an attempt is made to identify the socioeconomic characteristics of a community that influences the development and management of culture-based fisheries in village reservoirs of Sri Lanka. Socioeconomic data were collected from 46 agricultural farming communities associated with...
