The daily lives of Achill Island's inhabitants were heavily influenced by their relationships with the ocean, its resources and the seasons. Ireland's largest island, situated along its predominantly rural western coast, Achill remains in many ways idyllic and pastoral, descriptors used in the modern and recent historic era to draw tourists but also used in previous centuries to denigrate the culture and lifeways of the islands' inhabitants. Achill Island's maritime landscape, including its shor...

Small scale fishing profits in two communities in the Upper Paraná River floodplain (Porto Rico - PRI and Porto São José - PSJ villages) are assessed based on interviews carried out with professional fishermen. There is a high illiteracy level in both PRI (50%) and PSJ (44.5%). The main contributions to income are "vessel costs" and "fish consumption" by the family. Specific tackle (such as cevadeira) and gear used for fishing close to dams make the gear costs higher at PSJ, emphasising the hete...

Hoplosternum littorale (Hancock, 1828) (Siluriformes, Callichthyidae) is a middle size catfish, known in the Brazilian Amazon as ‘tamoatá’. It uses an accessory air-breathing organ to live in the poor oxygen swamps of the mouth of Amazon and Orinoco rivers. The tamoatá is the main fishery resource of the Marajó Island and it is caught in the flooded savanna of the Arari River basin, near the Santa Cruz do Arari city, Pará State. The tamoatá landing in the port of Ver-o-Peso, in Belém, represents...

Many methods have been used to establish the occlusal plane in complete denture prosthodontics. However, no single method seems to be fully accepted. Anteriorly, esthetic considerations help define the occlusal plane, and posteriorly the tongue, retromolar pad, and Stenson′s duct are considered. Some dentists bisect the space between the residual ridges. The technique of using the ala-tragus line (Camper′s line) to establish the occlusal plane is well documented. However, definitions of the ala-...

Background: Cervical transpedicular screw fixation is safe and is probably going to be the gold standard for cervical spine fixation. However, cervical transpedicular screw use in the Asian population can be limited as the transverse diameter in this group of patients may not be adequate to accommodate the 3.5-mm pedicular screw thus injuring the vital structures located in the close proximity of the pedicles. Thus lateral mass fixation remains the mainstay of treatment. The present study evalua...

Open water areas between fast-ice and pack-ice zones are frequently observed off Lutzow-Holm Bay, Antarctica. In such open waters, called polynyas or leads, which are exposed to the cold air, new sea ice can form with a high growth rate. So the open polynya releases large quantities of heat to the atmosphere and excludes high-salinity brine to the ocean. In 1990-1992 the 31st and 32nd Japanese Antarctic Research Expeditions conducted oceanographic observations in Lutzow-Holm Bay to reveal the at...

Myoliquefaction of fish musculature results in customer quality complaints and in huge economic losses, especially with regard to Pacific hake (Merluccius productus), farm-reared Atlantic salmon (Salmo salar), South African pilchards (Sardinops ocellatus) and Cape snoek (Thyrsites atun). Myoliquefaction, or ‘jelly flesh’, is caused by proteolytic enzymes released by the marine myxosporean parasite, Kudoa thyrsites, after the death of the fish. Currently there are no fast methods of detection for...

In many industrial and non-industrial applications the quality of a process or product is characterized by a relationship between a response variable and one or more explanatory variables. This relationship is referred to as profile. In the past decade, profile monitoring has been extensively studied under the normal response variable, but it has paid a little attention to the profile with the non-normal response variable. In this paper, the focus is especially on the binary response followed by...

The sustainability of anthropogenic activities at sea is recently gaining more and more attention. As regards shipping, emissions from ships into the environment of various nature (engine exhaust gases, anti-fouling paints leaching, ballast exchange, releases at sea of oil and other noxious liquid or solid cargoes, of sewage and of garbage) have been recognized as sources of pollution and therefore controlled and limited since a long time. The subject of noise emission has been identified only r...

The aim of this paper is to present the results of studies on the phenology of the spawning of fish in two lakes with different degrees of heated waters. The studies performed indicated that heating the waters distinctly hastened fish spawning in comparison to the same species of fish inhabiting waters with normal thermal conditions. Spawning usually occurred two to three weeks earlier in the heated Lake Licheńskie than it did in Lake Ślesińskie, which has waters with a natural thermal regime. A...

Stress among naval mariners is caused by a new environment in the form of climate, noise, defective food, diseases or injuries, and others. Stress is aggravated by the lack of information, conflicts between mariners, changing decisions of superiors. The strongest stressor military action is the fear of losing life or health.

This work aimed to experimentally evaluate the behavior of Brazilian freshwater fish species when submitted to a gradual increase in pressure, as well as sudden decompression's effects simulating the passage through a hydroelectric turbine. Four species from the São Francisco river basin were tested: Astyanax bimaculatus, Hypostomus sp., Leporinus reinhardti and Prochilodus costatus. For all of them mortality rates due to decompression were extremely low. However, the symptoms related to decompr...

A steady state box model was developed to estimate the methane input into the Black Sea water column at various water depths. Our model results reveal a total input of methane of 4.7 Tg yr<sup>&amp;minus;1</sup>. The model predicts that the input of methane is largest at water depths between 600 and 700 m (7% of the total input), suggesting that the dissociation of methane gas hydrates at water depths equivalent to their upper stability limit may represent an important source of methane into the...

Changes of chemical quality and physical properties of fish meal due to lipid oxidation under different storage conditions were studied using a 3-factor factorial design (2x2x4). Premium grade fish meal (72%protein) was divided into two portions, with and without ethoxyquin, each portion was then stored at either ambient temperature or 4oC for 0, 1.5, 3 and 4.5 months. The results showed no interaction between 3factors (supplemented with or without ethoxyquin, at 27-32oC and 4o and storage time)...

The current study examined the nutrient uptake efficiency of Ulva lactuca and Gracilaria chilensis cultivated in tanks associated with the wastewater of a land-based abalone culture. The experiments evaluated different seaweed stocking densities (1200, 1900, 2600, and 3200 g m-2) and water exchange rates (60, 80, 125, and 250 L h-1). The results show that both U. lactuca and G. chilensis were efficient in capturing and removing all of the inorganic nutrients originating from the abalone cultivat...

Parasitism, although the most common type of ecological interaction, is usually ignored in food web models and studies of trophic connectivity. Stable isotope analysis is widely used in assessing the flow of energy in ecological communities and thus is a potentially valuable tool in understanding the cryptic trophic relationships mediated by parasites. In an effort to assess the utility of stable isotope analysis in understanding the role of parasites in complex coral-reef trophic systems, we p...
