Regulatory Compliance in small-scale fisheries in Old Providence Island (Colombia)

Alayon, Laura Maria 01 January 2011 (has links) (PDF)
This research evaluates how contextual variables such as knowledge of the rules, the perception about punishment and formal enforcement levels, perception of social control, fishers’ attitudes about legitimacy of rules, and social/economic factors, affect compliance with fisheries regulations. The analysis is carried out in Old Providence Island [OPI]. A survey of 100 fishermen was completed and data from that survey is used to econometrically estimate a model of compliance choices. Results suggest that reports on compliance change depending whether the interviewed is asked about compliance or about violation. I argue that this seemingly inconsistency, reveals an implication on methodological approach. Contrary to the main literature on compliance behavior, in this research deterrence variables were not statistically significant in the econometric estimations. This result may be because sanctions and fines are not clearly established, reflecting the existence of structural problems in enforcement activities in the island. The results indicate that fishers adjust their violation with respect to other fishers’ behavior, and the knowledge about regulations. The probability of being a violator is higher for divers, and this fact is recognized by the fishers themselves.

Stress response and recovery of Atlantic Tarpon (Megalops Atlanticus) to catch-and-release angling

Horowitz, Laura B 15 May 2022 (has links) (PDF)
Atlantic Tarpon Megalops atlanticus support a catch-and-release fisheries in the United States and other territories such as Puerto Rico. Survival of angled fish is imperative to catch-and-release fishing yet numerous factors have yet to be looked at over a timescale to determine if laboratory and wild Puerto Rico tarpon experience increased stress and risk of mortality. To evaluate stress in simulated catch-and-release angling, laboratory trials were conducted over a 24-hour time scale with 2 varying intensities of simulated angling and various physiological parameters were explored. Blood samples concluded that simulating angling only had an interaction effect in time and fishing intensity in the factor of osmolality. In field studies, tarpon studied physiologically gave inconclusive results due to lack of a time scale. Field studies tracking mortality were completed by acoustic telemetry of angled fish in the San Juan Lagoon network. Studies resulted in a mortality that ranges from 4.5-20.5%.

Impact of localized harvest on the population of smallmouth bass (Micropterus dolomieu) of Lake Moomaw, Virginia

Garren, Daniel A. 25 August 2008 (has links)
Lake Moomaw, a 1,024-ha flood control reservoir in Bath and Allegheny counties, Virginia contains a migratory population of smallmouth bass that congregate in the headwaters of the reservoir during the spring spawning period, where they are vulnerable to a shore-based, harvest-oriented fishery. The extent of this fishery and resulting effects on the small mouth bass population were analyzed by means of a creel survey in the headwaters area during the spring spawning seasons of 1995 and 1996. Effort, catch, and harvest, as well as user characteristics and motivations data were obtained from direct interviews with anglers using this area. Estimates for 1995 indicated extensive fishing pressure per ha, with 1,167 angler hours per ha spent fishing for smallmouth bass in the headwaters, while in 1996 almost 1,400 angler hours per ha were spent in this area. Catch and harvest rates were relatively low and sustainable during both years, with 124 small mouth bass caught and 82 harvested in 1995, while 318 small mouth bass were caught and 222 harvested in 1996. An extensive capture-recapture study yielded estimates of exploitation rates for small mouth bass in the reservoir of 12- 15% annually. Exploitation of the whole-lake population occurring in the spring headwaters fishery was estimated at 4-6%, while the exploitation rate on the subset of the population using the headwaters during the spring was 11-14%. Analysis of movements of snlallmouth bass in the reservoir using ultrasonic telemetry and dart tag recaptures indicated that the subset of the population using the headwaters was mainly drawn from the upper and middle portions of the reservoir, and that significant amounts of spawning occurred in the lower section of the reservoir as well. Areas used by smallmouth bass for reproduction were documented with summer and fall electrofishing to determine relative abundance of young-of-the-year smallmouth bass in the reservoir, and showed spawning to take place throughout the reservoir. Densities of young-of-the-year shifted as fall progressed, with highest densities in the middle portion of the reservoir in early fall, indicating that reproductive inputs from the headwaters were realized in the lake as fall progressed. The headwaters fishery is a high-profile activity which, during 1995-96, had a low and sustainable impact on the Lake Moomaw smallmouth bass population. / Master of Science

Aqua + Culture: Intergrating Fish, Farming, and Flood-control Systems on Four Mile Run

Hu, Zhewei 11 August 2016 (has links)
This thesis begins with the study of a highly integrated agricultural system called dike-pond system in Pearl River Delta, South China. From the study, two aspects of dike-pond system are found interesting. One is the material flow in the system which makes full use of the by-products. The other is the function of preventing flooding by protecting crops on the dike and increasing water storage capacity with ponds. Duplicating the system to other parts of world seems impossible because of the weather conditions, technical requirements to operate the system and its intensive labor requirement. However, in a broader view, it seems possible to apply the concepts of reusing "waste" and preventing flood to other places. With the inspiration of this system, this thesis studies how the concept might be adapted to Washington Metropolitan area. Several specific questions are critical to the inquiry: How to integrate different components into a system according to local situation? How to produce multiple products that feedback into the flow of materials and resources just like dike-pond system? How to reuse 'waste' or forgotten resources? How to prevent floods without using an engineered flood wall? How to create a place that people can have different fishing experiences in urban region? How to provide a habitat for urban wildlife? My thesis addressed these questions through a design for a public space along the downstream of Four Mile Run in Arlington, Virginia. With design criteria derived from case studies and literature review, this project aims to control floods, cycle organic matter in wetlands, ponds and farm fields, provide fishing places, fish habitat, open spaces... All in an integrated system with little waste and a wise reuse of the "waste" water. / Master of Landscape Architecture

An Urban Koliwada: Redevelopment of a Fishing Village in Mumbai, India

Dinoy, Ashvini Mary 13 September 2018 (has links)
"Looked into the streets - the glaring lights and the tall buildings - and there I conceived Metropolis" exclaimed the Austrian filmmaker Fritz Lang at the sight of New York. This visit inspired him while creating the sets and background for the radical movie Metropolis released in 1927. Taken right after World War I, the movie set in 2026 was heavily symbolic with German expressionism and it captured a projected socio-economic condition which was a direct result of the fears of the people at that time. The working class lived in subterranean spaces distraught with mundane labor while the affluent lived in skyscrapers and exotic terraced gardens and drove around in elevated highways. The city seemed to be this well-oiled machine existing only to cater to the needs of the upper class. The poor eventually try to overthrow the rich. The movie finally ends with the message of hope, that the mediator would create harmony among the classes and create peaceful coexistence. The city of Mumbai in 2018 is in many ways - the Metropolis. When a city develops, it does not seem to cater to all sects of people. In fact, there seems to be a parallel relationship between the size of the city and its level of socio-economic disparity: the larger the city the less equal it tends to be. More often than not, the true soul of the city lies within that lower stratum of society who often live in slum-like settlements. Can architecture play the Mediator and bring about a connect? / Master of Architecture / At the time of Indian Independence in 1947, Gandhi said that “India is to be found not in its few cities but in its 700,000 villages. Villages were self-sustaining units which were rich in culture and tradition. He believed that the revival of the villages and all its cottage industries, handicrafts and agriculture was India’s answer to development. However in 2018, there are only about 597,464 census villages . At this rate, within a few centuries, India would loose its identity and will look like every other country in the world. Anybody who could afford to travel. moved to the cities. Villages are constantly abandoned and some get engulfed or morphed into cities. Cities grow at such rapid rates with the latest building technologies usually ignoring the needs of the people its supposed to serve. Is the city developed only for the rich and affluent? Can architecture support social inclusion and break down spatial segregation within a megacity? Can we capitalize on a city’s history and rich traditions without destroying them? Can a village survive a city? My thesis attempts to answer some of these questions through case studies, research and finally applying some of these theories and concepts on to a project that involves the redevelopment of a fishing village in the heart of Mumbai, India.

The Aesthetic of Love

Blissett, Brandon 14 July 2008 (has links)
Indigenous architecture is a loving response to the natural conditions surrounding ones inhabitation of architecture. It is designed and built by those who will inhabit it and is necessarily designed in coordination with both environmental considerations and practical (or use-oriented) considerations. The product of such a building shows the love present in it both as an independent architectural entity and as an inhabited structure. The late 20th century has seen a revival with regard to appreciating this aesthetic. The 'green' movement had hoped to open people's eyes to a certain aesthetic of conservation but unfortunately has lost sight of the ideological foundations of its existence. My proposal is to look back to these roots of architecture. Not to revert architecture to mere building, but to find the aesthetic through the love put into the creation of a purposeful structure intended for a specific set of criteria and inhabitants for an intentional duration in a specific spot. We must look intently at the indigenous builders for how to find the balance of sustainability, response to environment and the physical aesthetic. / Master of Architecture

What Fishing Tackle Should I Bring Today?: Safety Harbor Resource Collection Tools as Adaptations to Aquatic Environments

Davis, Richard J, III 01 January 2024 (has links) (PDF)
This thesis reports on the results of research conducted to determine whether technological adaptations to local environmental conditions can be observed through geospatial and artifact analysis of Safety Harbor collections from the Tampa Bay region of Florida. Past artifact and spatial analysis did not take advantage of modern technological advancements when studying how human-environmental interactions can influence certain adaptations to local conditions. In this project, GIS was used to reconstruct local aquatic environmental conditions of waterways adjacent to Safety Harbor sites. New statistical software programs have also proven themselves useful to archaeologists seeking to conduct hypothesis testing of artifact data. The Safety Harbor artifacts used in this analysis were accessed through the Alliance for Weedon Island Archaeological Research and Education (AWIARE) lab on Weedon Island. Fishing artifacts from these sites underwent hypothesis testing to identify any statistically significant morphological differences. Geospatial analysis was also conducted to determine if these differences correlate with differing aquatic environmental conditions. Technological adaptations to local conditions at these three sites were then compared to those previously identified in research on the Calusa. Ultimately, it was found through this research that Safety Harbor peoples did adapt their fishing technology differently depending on the aquatic environment adjacent to their occupation site. Additionally, the adaptations observed in Safety Harbor fishing technology were similar to those identified in research on the Calusa.
