The paper will report on the development of a new set of wealth-based
Fishery Performance Indicators (FPI) for evaluating and comparing the
worlds fisheries management systems. A wealth-based fishery management
system is one that is ecologically sustainable, socially acceptable, and
generates sustainable resource rents or profits. The Fishery Performance
Indicators...
There are only three fundamental sources for increasing seafood supply: 1) better management and utilization of wild fish stocks, 2) aquaculture and 3) aquaculture-enhanced ‘wild’ fisheries. However, nearly all of the significant growth in global seafood harvest and international trade over the past three decades has, and in the future...
Experiments were performed to determine whether a direct
correlation exists between the growth rates of tall and dwarf peas
grown either in the light or in the dark and endogenous gibberellin
(GA) content. Three separate but related experimental approaches
were utilized: (1) the determination of possible qualitative and /or
quantitative...
Beginning with the basic equations from the theory of elasticity
and employing a model of crack propagation based on the concept of
a constant plastic energy absorption per unti of crack extension, the
commonly accepted power law of fatigue crack propagation was derived.
This derivation uses an extension of the...
The impressive growth of world aquaculture has led to profound transformations in the economic structure of several capture fisheries. Evidence from the Alaska salmon fisheries supports this argument as a connection has been suggested between the recent trends of declining ex-vessel prices and the rapid development of salmon farming elsewhere...
Because of their high cost, reducing the number of boards used to fill an
order of dimension parts is an important goal in a lumber rough mill. FLCO
(Fuzzy Logic Cutting Order) is a computer program that achieves this goal.
Using the concepts of fuzzy logic control, FLCO provides a...
The rapid increase in global aquaculture production since the early nineties has increased the demand for fishmeal as an ingredient in aquafeed. This increase has been hypothesized as the source of disruption in the fishmeal market by researchers such as Delgado et al. In this paper we evaluate whether or...
