The experiences on reproductive management of native specie such as Petenia splendida (Tenhuayaca) in the last four years in Tabasco, Mexico has generated enough information to allow the development of a technological package for supporting sustainable rural production, particularly in areas where most of the population belongs to ethnical groups....
Global aquaculture production increased with an average rate of 10% per year since 1990 and 90% of
aquaculture production comes from developing countries thus providing livelihood and income especially
to marginal groups who have limited access to resources such as agricultural land and financial capital.
Geographical information systems (GIS) based...
Whatever the quantity and the rate of water utilization is, economic principles indicate that there will
always be other water utilization methods which might increase the efficiency of the use of this resource.
Due to the geo-climatic position of Iran, this country finds itself in a water deficit situation as...
A community based sea urchin (Tripneustes gratilla) culture was chosen as an alternative livelihood by
fisherfolks of Nalvo, a fishing village along the South China Sea in Sta. Maria, Ilocos Sur, Philippines.
The sea urchin culture was adopted among fishermen to augment their rapidly declining income from
fishing. The said...
Shrimp farming in Iran is one of the fast growing segments of the economy. In 1994, around 1%
of Iranian shrimp production was farmed and by 2003 the share of shrimp farming increased to
60%. In spite of the fact that shrimp culture had relatively rapid growth in last decade,...
Wholesale demand systems for live reef food fish in Hong Kong are analysed using the Linear Approximate Almost Ideal Demand System (LA/AIDS). Results suggest that price elasticities of demand are inelastic, with relatively high-valued species exhibiting greater elasticity than relatively low-valued species. Cross price elasticities are negative suggesting that different...
Economists have generated numerous studies analyzing how a move to rights-based fishery management from open-access management affects fish harvesters' behavior. Conversely, the impacts that such a change in management can have on fish processors has received relatively little attention. This paper presents a simple two-product processor supply model to show...
A bio-economic model, based on Faustmann rotation, was developed to analyze the relevance of
removing thinning activities which are part of the dominant technology used in blue mussel production in
Canada. Removing these density control activities (thinning) seemed a profitable option to producers. It
was thought that this collector line...
The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal
diseases. In order to analyze the economic effects of aquatic animal disease control, the specific factors
and magnitudes of benefits and costs are identified with and without the proposed project for the disease
control. These...
In natural resource economics, we sometimes observe a situation in which producers and consumers have
direct access to the factors of production or can use some consumable products with little or no
transformation. These goods are commonly referred to as “gifts of nature”. A factor of production is
considered a...
