Abstract

Purpose

This paper analyses Roman fish tanks, which have functional elements that could be used to research on palaeo-sea-levels. Thus, the conditions of 37 installations in the Western Mediterranean basin are reviewed to identify those that have the best environmental and constructive conditions to be analyzed.

Design/methodology/approach

The methodology was largely based on the review of existing scientific bibliography dealing with sea-level variations from studies on historical constructions, existing historical documentation on Roman fish tanks on the Mediterranean coast, as well as the fieldwork carried out in fish tanks on the Mediterranean coasts.

Findings

The Roman coastal fish tanks located in the shoreline of the Western Mediterranean Sea have turned out to be an excellent indicator of sea-level changes. Nevertheless, current coastal retreat, erosion and storm surges are posing significant threats to their preservation, and they could be considered as a heritage at risk of disappearance. Moreover, variations in the tectonic behaviour of the different coastal sectors make it challenging to select these facilities as an indicator of the sea level.

Originality/value

The analysis of Late Holocene sea-level changes and palaeoenvironments from archaeological and biological evidences, although not without difficulties, is very convenient because it provides very precise data that cannot be obtained with other absolute dating methods. This approach is increasingly gaining popularity with researchers and is very innovative in its method of combining the results of several scientific disciplines.

Abstract

Purpose

Gadoid fish and hake are the species of fishes most frequently imported to the Czech Republic. The purpose of this paper, cross-country hygiene study, is to determine sea fish fraud labelling on the Czech market and catering.

Design/methodology/approach

In total, 57 samples of commercial Gadoid fish product from different manufacturers, distributors and catering facilities were gathered. Gadidae family, hake (Merluccius spp. Raf.), saithe (Pollachius virens L.), Atlantic cod (Gadus morhua L.), Alaska pollock (Theragra chalcogramma Pall.), were detected in fish meat, fish products and fish meals by the qualitative PCR method.

Findings

In total, 47 samples were labelled as a Gadoid fish, which were confirmed in 43 cases. Six samples were labelled as a hake and were confirmed in five samples. Four samples were labelled as a fish fillets. Three samples of fish fillets were identified as a hake and one sample was detected as a mixture of Alaska pollock and Atlantic cod.

Social implications

In recent years, due to increasing interest from consumers in the sea fish meat market, accurate Identification of fish species has become more important. The mislabelling of sea fish species, whether intentional or not, was on observed on the Czech market and in catering facilities. Economic factors influence the accuracy of labelling of fish meat, which is a concern as mislabelling can threaten public health.

Originality/value

The study was concentrated on the monitoring of hygiene and quality of food products and catering facilities. This study provides greater awareness of the condition and quality of food on the market and to the extent of fraudulent practices amongst dealers and producers.

Abstract

The purpose of this chapter is to illustrate the contribution made by migrants in the territory that hosts them, particularly when they transfer their knowledge to members of the community. In the specific case of the sea urchin fishery, it is described how the Morishita family in Baja California undertakes the sea urchin value chain, from the location of population banks to the commercialization of the product in the Japanese market and, by therefore, the promotion of development in rural places while starting a culture of export and currency generation. An adventure of opportunities that has been successful for more than 50 years, whose origin is the sustainable use of “a plague” that today is a delicacy for many.

Abstract

Purpose

The four purposes of this study are to understand the development and the current status of Taiwan’s far seas longline tuna fisheries through a review of the literature and interviews; to investigate the attitude of Taiwanese fishing vessel operators fishing in the Indian Ocean concerning the use of transportation under the influence of various factors; to analyze the relationship between changes in the transportation behavior of Taiwanese fishing vessel operators and various factors; and to provide suggestions to government and industry associations concerning the development of viable response strategies.

Design/methodology/approach

This paper uses methods including factor analysis and the analytic hierarchy process to analyze questionnaires collected from industry personnel and governmental personnel involved in the supply chain system of the longline tuna fishery in the Indian Ocean.

Findings

It is found that 16 assessment criteria in four major dimensions have major influence on the choice of cold chain transport. An assessment of all dimensions indicates that reefer ships are still the preferred means of transshipping frozen catch.

Originality/value

This paper seeks to investigate factors affecting choice of cold chain mode of transport from the perspective of Taiwanese companies operating longline tuna fishing vessels in the Indian Ocean, which are chiefly motivated by the need to reduce operating costs, and also looks at their choices of means of transport.

Abstract

Purpose

This paper aims to assess the willingness of individuals living in coastal communities affected by climate change to financially support mitigation policies towards the preservation of marine ecosystems and fish resources and to identify the key drivers of their behaviour.

Design/methodology/approach

A survey was carried out involving 994 people living in three main Italian coastal communities. To investigate the main factors affecting Italian coastal communities’ willingness to pay (WTP) to support climate change mitigation measures to protect the marine ecosystem and fishery resources, a Tobit regression model was implemented.

Findings

The results show that these communities are likely to pay to safeguard fish resources and the marine ecosystem, owing to their social and economic importance for these communities. In particular, this study’s findings highlight that the individuals’ attitudes towards climate change, social pressures and their perception of the phenomenon play a significant role on their intention to support mitigation policies. Moreover, the findings demonstrate that the communities most threatened by the negative effects of climate change are more willing to contribute financially to protect fish resources and the marine ecosystem.

Research limitations/implications

A limitation is related to the adopted methodology. In particular individuals’ intention to adopt pro-environmental behaviours does not always translate into real WTP through additional taxes.

Originality/value

The value of the research stems from its unique collective cross-communal comparison of attitudes and intentions, its parallel identification of behavioural drivers at the individual level and its prescriptive conclusions of both scholarly and practical worth.

Abstract

We are growing accustomed to shock tactics of the US Administration in dealing with toxic residues in food or additives which are a hazard to man, as well as the daily press infusing sensation, even melodrama, into them, but the recent action of the FDA in calling in from the food market several million cans of tuna and other deep sea fish because of the presence of mercury has had the worthwhile effect of drawing world attention to the growing menace of environmental pollution. The level of mercury in the fish is immaterial; it should never have been there at all, but it stresses the importance of the food chain in the danger to man and animal life generally, including fish beneath the sea. Without underestimating risks of pollution in the atmosphere from nuclear fission products, from particulate matter carried in the air by inhalation or even skin absorption, food and drink, which includes aqua naturale would seem to be the greatest danger to life. What these recent events illustrate in a dramatic manner, however, is the extent of pollution.

Abstract

Illegal, Unreported and Unregulated (IUU) fishing is one of the most complex and serious environmental crimes affecting marine ecosystems around the globe and depriving coastal communities of vital subsistence resources. Many strategies have been developed to deal with the problem in hopes to eventually eradicate it. This chapter will review a total of 163 approaches implemented around the world, and classify these interventions according to the 25 techniques of situational crime prevention (SCP), one of the most effective crime reduction measures frequently used to deal with a variety of crime problems. This chapter will analyse what types of techniques are most and least frequently used and why; note similarities and differences among these intervention strategies; as well as examine whether there is a distinct difference between developed and developing countries in their use of particular SCP measures to combat IUU fishing. This chapter will also present examples of particularly interesting initiatives, and propose new ways forward.

Abstract

Purpose

The aim of the paper is to shed light on the use of chitosans and chitooligosaccharides as biopreservatives in various foods animal. Foods of animal and aquatic origin (milk, meat, fish, eggs, sea foods, etc) become contaminated with a wide range of microorganisms (bacteria, molds and yeasts) during harvesting, transporting, processing, handling and storage operations. Due to the perishable nature of these foods, their preservation is of utmost importance. Though many synthetic chemicals are available, yet their use is quite restricted due to their hazardous effects on human health.

Design/methodology/approach

Within the domain of food industry, traditionally chitosan is used for biopreservation of foods, which is well known for its nutritional and medicinal properties in human nutrition. However, chitooligosaccharides also possess a number of nutraceutical and health promoting properties in addition to their preservative effect and shelf-life extension of foods. In this study, the comparative effects of both chitosan and chitooligosaccharides on preservation of foods of animal and aquatic origin have been summarized.

Findings

Though chitosan has been extensively studied in various foods, yet the use of chitooligosaccharides has been relatively less explored. Chitooligosaccharides are bioactive molecules generated from chitosan and have several advantages over the traditional use of chitosan both in food products and on human health. But unfortunately, little or no literature is available on the use of chitooligosaccharides for preservation of some of the foods of animal origin. Notable examples in this category include cheese, beef, pork, chicken, fish, sea foods, etc.

Originality/value

This paper focuses on the effects of chitosans and chitooligosaccharides on the processing and storage quality of foods of animal and aquatic origin, which offers a promising future for the development of functional foods.

Abstract

The object of this paper is to know what are the artificial radioactive nucliides in marine environment, where and what are the sources of their products, what are their effects to the health of marine and land populations. With this view in mind we shall discuss the large‐scale production of man‐made artificial nucliides that have been poured into the oceans since about the middle of the present century. The first significant release of radioactive nucliides to the marine environment began in late 1944 in USA with the discharge of effluent from her reactors at Hanford Atomic Plant to the North East Pacific Ocean via Columbia River. In the following year, July 1945, an atom bomb was tested successfully and the detonation of two more tests of atom bombs at Bikini Atoll (Pritchard et al, 1971; Seymour, 1971) introduced enough amount of radioactive nucliides into the North Equatorial Current System of the Pacific Ocean.

Abstract

Discusses marine environment management and maximization of the sustainable use and non‐use values of the flow of goods and services generated by that environment. Expands on the traditional economic model of fishery management to include the protection of non‐use values. Assesses international agreements made to include the protection of non‐use values of the marine environment, and examines the conflict between GATT rules and unilateral attempts to protect existence values. Proposes solutions based on the full cost pricing principle.
