Needles in a Haystack: Cost-Effective Sampling of Marine Sport Anglers

An obstacle to conducting economic studies of marine sport anglers is the difficulty and expense in drawing a representative sample. Unlike inland fishing, where licenses are required in all states, only selected states require a marine sport fishing license and these licenses usually only cover selected marine fishing activities. Currently, there are no low cost methods of obtaining a representative sample of marine anglers because they are generally not licensed, use multiple access points, and represent a small proportion of the general population. The difficulty and expense of drawing a representative sample may have stifled attempts to study marine anglers. We test alternative sampling strategies by comparing the characteristics of a representative sample of experienced marine anglers with the characteristics of two other samples using multivariate and univariate analysis techniques. We conclude a sample of marine anglers drawn from the population of licensed inland anglers is not significantly diffe...

Marine Reserves: Rates and Patterns of Recovery and Decline of Large Predatory Fish

A major objective of the use of marine reserves in management of coral reef fisheries is protection of a critical spawning stock biomass to ensure recruitment supply to fished areas via larval dispersal. However, very little empirical evidence exists on the rates and patterns of increase of density and biomass of target species following the closure of a coral reef or part of a reef, nor on how quickly any gains potentially useful to fisheries can be lost if reserves are subsequently opened to fishing. This paper presents empirical evidence derived from the visual monitoring of density and biomass of large predatory coral reef fish (Serranidae (Epinephelinae), Lutjanidae, Lethrinidae and Carangidae as a group) in two small marine reserves and at two control sites in the Philippines from 1983 to 1993. At one reserve (Sumilon) a complex history of management allowed seven measurements of density and biomass at durations of reserve protection ranging from ‐2 (i.e., fished for 2 yr) to 9 yr. At the second reserve (Apo), seven measurements were taken at durations of reserve protection ranging from 1 to 11 yr. Density of large predators provided an excellent indicator of the effects of marine reserve protection and fishing. Density decreased significantly twice when the Sumilon reserve was opened to fishing (1985, 1993), and increased significantly three times following durations of marine reserve protection of 5 yr (Sumilon reserve and nonreserve sites, 1987‐1991) and >6 yr (Apo reserve beyond 1988). Density of large predators at the Apo nonreserve site (open to fishing) did not change significantly, remaining low throughout the study. Significant positive linear correlations of mean density of large predators with years of reserve protection were observed at both reserves. The rates of increase were 1.15 and 0.72 fish·1000 m‐2·yr‐1 at Sumilon and Apo reserves, respectively, with mean density ranges of ≈ 4‐17 fish/1000 m2 (‐2 to 9 yr of protection) at Sumilon and 0.5‐9.5 fish/1000 m2 (1‐11 yr of protection) at Apo. The pattern of increase of mean biomass with years of reserve protection was more curvilinear than that of mean density, particularly at Sumilon, where a slow increase was observed in the first 3‐5 yr (reflecting delayed recruitment and a natural delay to the period of maximum individual mass growth), followed by an increasing rate over the next 4 yr. Mean biomass ranges were ≈ 1.5‐18 kg/1000 m2 (‐2 to 9 yr of protection) at Sumilon and 1‐10.5 kg/1000 m2 (1‐11 yr of protection) at Apo. At Sumilon reserve, 2 and 1.5 yr of unregulated fishing, respectively, eliminated density and biomass gains accumulated over 5 and 9 yr of marine reserve protection.

Environmental effects of marine fishing

Abstract Some effects of fisheries on the associated biological systems are reviewed and management options and their inherent risks are considered. In addition to the effects on target species, other sensitive groups impacted by fishing are considered including marine mammals, turtles, sea birds, elasmobranchs and some invertebrates with low reproductive rates. Other impacts discussed include the destruction of benthic habitat, the provision of unnatural sources of food and the generation of debris. Management options are considered including the designation of marine protected areas, risk aversion, and the burden of proof. A balanced consideration of the risks and consequences of ‚Type 1’︁ and ‚Type II’︁ errors is advocated.

Antiquity of marine fishing in South-east Queensland

The Moreton Region Archaeology Project has investigated coastal sites in South-east Queensland since the late 1970s. Despite Pleistocene occupation in the area adjacent to the then coastline, and more recent coastal settlement dating to the later Middle Holocene, evidence of a well developed marine fishery dates only to the most recent 2,000 years. According to the data presently available, this does not appear to relate to taphonomic factors.

Bone stable isotope studies in archaeology

Stable isotope ratios of carbon and nitrogen in bone have become increasingly frequent inclusions in archaeological reports over the past few decades. The majority of such studies has been done in North America, where the use of marine foods and the introduction of maize have been monitored. Similar questions have been addressed in Mesoamerica and South America. In Europe, stable isotope ratios have documented the shift from marine fishing and gathering to agriculture in coastal areas and the introduction of millet in parts of eastern and southern Europe. Much work remains to be done in Asia, where millet replaced early C3 plant foods and, in turn, was replaced by rice. In Africa marine adaptations, freshwater fishing, agriculture, and pastoralism all yield diagnostic isotopic signatures. We review these studies, discuss areas requiring further study, and close with discussions of areas promising interesting future developments.

Share contracts and their rationale: Lessons from marine fishing

Most of the existing literature on share contracts is based explicitly or implicitly on agriculture, a sector in which share contracts are seldom dominant and apparently on the decline. Moreover, since agricultural activities have some rather special characteristics, the purpose of the present article is to analyse contractual choice and especially the choice of share contracts in a sector in which share contracts are dominant, namely fishing. In the process of explaining the dominance of share contracts in fishing, the article also explains (a) some heretofore neglected features of these share contracts, such as the way in which shares are calculated and the treatment of repair and maintenance expenditures, (b) the nature and extent of interlinked transactions, (c) the exceptional cases where share contracts are not used, and (d) the relevance of varying environmental conditions and especially those of poor developing countries to the nature of contracts in fishing, and to the differences therein between...

Synthetic aperture radar imaging of sea surface life and fishing activities

During the Halieutics Radar Experimentation Mediterranean Sea (HAREM) experiment, conducted in August 1989 in the Gulf of Lion, synthetic aperture radar (SAR) images of the sea and lagoon surface and concurrent independent observations and measurements were collected in order to test the potential of some applications of SAR imaging theories to halieutics. These theories have been developed to explain the SAR signal modulation in relation to small variations of water roughness induced by internal wave or current or wind field variations. Analysis of the HAREM data indicates, for the first time, that the marine surface life and fishing activities generate an SAR signal modulation of comparable order of magnitude at the C-band (5.3 GHz). The results of satellite simulations, considering ERS1 characteristics, are presented and show good promise for fishing activity surveys, indicating that the aerial SAR data and, under certain conditions, satellite SAR data may greatly enhance and complement classical methods used in fishery management.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A discrete-choice model of recreational participation, site choice, and activity valuation when complete trip data are not available

A discrete-choice model of the demand for site-specific recreational activities is developed and estimated. It simultaneously predicts both how many trips the individual will take and which site will be chosen on each trip. The model is formulated to estimate demand when the data set reports the total number of trips in a given time period, but the actual destinations for only a subset of the total. The model also includes a correction for sample-selectivity bias. The application is marine recreational fishing. The consumer's surplus associated with any change in supply conditions is derived and used to assess the impact of changes in species availability.

Social and cultural characteristics of fishing peoples

The paper focuses on interrelationships between characteristics of the environment and technology of marine fishing and aspects of the society and culture of fishermen. Specifically, aspects of the work environment such as resource variability, relative isolation of the workplace, workplace hazards and spatial constraints, control over productive factors, and common property characteristics of the resource are related to social and cultural attributes such as migration and seasonal labor, sexual division of labor, workgroup structure, status of women, ownership of productive equipment, and insulation of fishing communities. It is argued that it is essential to understand the interrelationships between these various variables prior to making any decisions which would affect the fishery.

Regards sur l'aquaculture mondiale: Exposé introductif à la réunion de la Fondation Internationale pour la Science sur l'Aquaculture - Abidjan, Côte d'Ivoire

After some definitions of aquaculture terminology, some quantitative data are given concerning world-wide aquaculture — annual production 6 million tonne (1975). In addition specific production details are presented for the most important aspects: fish breeding, shellfish breeding, crustacean breeding, and culture of aquatic plants. The future of aquaculture is considered in production terms: 20 million tonne expected in 1985 and 50 million in the year 2000, in order to supplement the resources resulting from marine fishing. However, aquaculture is subject to risks, especially in Africa, due to a lack of hydrobiological, ichthyological and zootechnical knowledge, to which are added problems of a sociological and juridical nature.

モーリタニアの漁業

The Islamic Republic of Mauritania is one of the least less developed countries. G. N. P. per head was only 270 U. S. dollars in 1978. This country has, however, two rich natural resources; the high-grade iron ore and one of the richest marine fishing grounds.Since 1959, many foreign fishing fleets from Japan, Spain, Italy, Korea, Soviet Union etc., have been operating to catch fish in this marine fishing ground. The catch consists mostly of mackerels, sardines, shads, breams octopuses, and crawfishes. In 1976, total catch reached to 1570 thousand tons in the Sahara coastal division.Since 1972, the government of Mauritania has limited the number of foreign trawlers and levied the tax on trawlers by means of expansion of the territorial waters, to protect the national fishery resource and to grant the profit to Mauritanian fishermen.Mauritanian fishery is classified as follows:(A) Modernized fishery (trawlers fishing managed by Maurutanian companies)(B) Local fisheries.(a) Freshwater fishing in the river of Senegal.(b) Seasonal migrant fishing by the Imuraquen.(c) Local coastal fishing by the Wolof in Mauritania.The Japanese government is making the financial and technical aids to (b) and (c). The local coastal fishermen are organizing cooperatives.

Predicting Marine Recreational Fishing Patterns from Boat Characteristics and Equipment

Abstract This paper reports an approach for predicting general marine fishing locations and distances traveled offshore for fishing from boat equipment data. Discriminant analysis indicated that bay and offshore fishing boats could be distinguished with 80% classification accuracy from horse-power, fuel capacity, and boat length. Multiple regression analyses verified that fuel capacity and presence of radios and long range navigation (LORAN) were significant predictors of offshore fishing distances.

Values of Marine Recreational Fishing: Measurement and Impact of Measurement

There is a rich literature in economics dealing with the inefficiencies of the competitive allocation of open access resources. Economists working in the area of outdoor recreation have devised several methods for simulating market demand curves for estimating social benefits. Recreational fishing, most especially marine fishing, is one of those activities competing for the use of open access resources that requires the estimation of social benefit functions. In the absence of good information about net social benefits for open access activities, decision makers tend to respond to measures which reflect the total level of economic activ-
