Artisanal fishermen, because of their direct and frequent contact with the aquatic environment, possess a wealth of knowledge about the natural history of the fauna of the region in which they live. This knowledge, both practical and theoretical, has been frequently utilized and integrated into academic research. Taking this into consideration, this study discusses the ethnoecological knowledge...
The paper describes how the Icelandic fleet increased from 1980 to 2005, as well as the number of fishermen employed in the various sections of the fleet. All categories of the fleet have increased considerably in tonnage, while the number of fishermen has declined. At the same time the catch per man-year at sea has increased, rendering the Icelandic fisheries among the most efficient in the wo...
The interaction between economic and ecological dynamic systems is analyzed with a multi-agent dynamic game model of fishery management. Multiple actors (fishermen) harvest multiple fish types and adapt the amount and allocation of their investments to their value functions, which are given as net profits of the fish harvest sold for a market price. We introduce and compare two different decisi...
OBJECTIVE Migrant populations are at higher risk for HIV infection. Access to health care and STD treatment is thought to lower this risk. This study aims to examine determinants of STD history and treatment and healthcare behaviours among fishermen in the Gulf of Thailand and the Andaman Sea. METHODS A cross sectional survey of fishermen working on commercial fishing trawlers was conducted i...
This study explored occupational safety practices and regulatory compliance in a representative sample of Maine commercial fishing vessels. Data were collected on demographic characteristics, safety equipment and training, and regulatory compliance during at sea boardings of working commercial fishing vessels (n = 259). Trends in safety and compliance were explored using standard comparison tes...
In this paper we propose a discrete-time dynamic model for studying the time evolution of fish stocks in an aquatic environment divided into two adjacent patches, one characterized by an imposed constant fishing effort and another one where fishermen are free to decide the quantity to harvest according to oligopolistic competition taking into account economic and biologic externalities. Given t...
Competitiveness pervades life: plants compete for sunlight and water, animals for territory and food, and humans for mates and income. Herein we investigate human competitiveness with a natural experiment and a set of behavioral experiments. We compare competitiveness in traditional fishing societies where local natural forces determine whether fishermen work in isolation or in collectives. We ...
Eczema associated with bryozoans is a form of occupational dermatosis caused by a living animal, involving contact eczema, occasionally associated with photosensitivity and concerning fishermen on a quasi-elective basis. This affection can prove to be extremely disabling, frequently generating disastrous social consequences, since the eviction of the responsible allergen is very often synonymou...
The Indian coastline is about 7517 km long, and on this coast line lie India's four high HIV prevalent states: Maharashtra , Andhra Pradesh, Karnataka, and Tamil Nadu. In the Indian context, when it comes to the mobile population, it is mostly truckers and labour migrants who have been given more attention from the National AIDS Control Organization. There are hardly any studies available in In...
Fishing is one of the most dangerous professions in the world. India with one million active fishermen population still lacks a reliable boat-to-shore communication network. Fishermen with smaller boat are more vulnerable to the wilder nature of the ocean, due to dynamic sea current, wind speed, direction and wave heights, etc. They form 80% of the entire fishing community. There being no physi...
