This dataset contains trace-element data, descriptive information, and photographs for 328 field clays sampled in the Valley of Oaxaca, Mexico; mineralogical data are presented for a subset of the samples. The clay samples were generated as part of a valley-wide sampling strategy designed to capture spatial variation in clay composition...

Balanced feed represents approximately 60 % of production costs in fish culture and ration size has significant effects on this parameter. Ration size varies according to culture strategies and producer knowledge. It can also have environmental implications since feed can be a pollutant. A bioeconomic model was developed for an...
Spiny lobster (Panulirus argus) and related species represent one of the most important commercial fisheries targeted within the Gulf of Mexico and Caribbean regions. This important fishery extends from Florida (USA) to Brazil. The longlived, pelagic larval stage within the life cycle of spiny lobster reveal this species to be...
Low yields caused by viral diseases and their financial consequences are the most important risks jeopardizing commercial shrimp culture in Mexico. Hence, farmers are continuously testing different production strategies to keep their operations into profitable margins. An optimization model was designed based on a farm's (139 ha) database (2001-2005) to...
Tilapia culture in Yucatan State, Mexico, is largely semi-intensive. The producers are mostly poor farmers who receive government subsidies for purchase of fingerlings and balanced feed. Feeding practices are often inadequate (satiety rations), moreover, producers frequently suffer financial and resource shortfalls. During feed shortages producers are known to use empirical...
The aim of the paper is to explore the economic environment that makes informal fish trading possible, the nature of these activities and how they are interconnected or might stimulate IUU fishing activities in the port of Progreso, Yucatan, Mexico. The main argument is that fish trading by middlemen has...
A canvass of the resource economics literature of the last thirty years yields a limited number of applications of economic theory to the problems of recreational fishing. This neglect may be linked to the short shrift given to the control of recreational fisheries (relative to commercial fisheries) by fisheries managers...
The shrimp fishery accounts for more than one-half of the total revenues generated by commercial fishing activities in the U.S. Gulf of Mexico. Due to its historical open access nature the harvesting sector has historically been overcapitalized (from an economic perspective) resulting in a suboptimal generation of rents. Various management...
