Salted-Fish industry in Roman Lusitania: Trade Memories between Oceanus and Mare Nostrum

Initiated by Augustus, Rome’s Atlantic policy seems to have been consolidated in the age of Claudius, with the acknowledgement of the economic potential offered by the Atlantic region. It is in this context that we must understand the development of the salted-fish industry in Lusitania. In the same geographical contexts, and in close relationship with fish-processing factories, are known about 20 pottery centres producing amphorae, located in the regions of Peniche, Sado and Tejo valleys, and the coasts of Alentejo and Algarve. This production extended in time beyond the end of the Western Roman Empire and up to the end of the 5th and 6th centuries, according to the archaeological data of some amphora kilns and fish-processing sites. The identification of Lusitanian amphorae in distant consuming centres and several shipwrecks in the Mediterranean basin confirm the long-distance commerce and the total integration of this “peripheral” region into the trade routes of the Roman Empire.

Culture alternative medium for the growth of extreme halophilic bacteria in fish products

Halotolerant or halophilic (Archaeabacteria) microorganisms can be found in salted and ripening fish products that are not affected by salt. They can be moderate or extremely halophilic bacteria. The extremely halophilic bacteria require between 15-30% of NaCl for growth. The extremely halophilic archaeobacteria may be selectively isolated in different media. The aim of this work was to determine the effectiveness of the Salt-Agar-Milk medium, a medium modified in our laboratory through the addition of MgSO4 and KCl - named SAMm, and its effect on the bacterial growth by means of comparison with other media, with and without milk, determining time of incubation and counting. Two samples of salted fish from local fish salting factories and two laboratory strains were used. The factory samples were matured anchovy and anchovy fillets in oil, and the laboratory strains were: Haloarcula spp. (proteolytic) and Halococcus spp. (non-proteolytic). The following media were alternatively used for the isolation of extremely halophilic bacteria: IRAM; Formulation of Gibbons and collaborators, Cod Milk agar, and SAMm. IRAM and Gibbons were also used enriched with milk. In the SAMm medium, there were obtained count values similar or higher than the ones of the traditional media; besides the simplicity of its elaboration, the possibility to obtain positive results two or three days earlier also added to its benefit. Consequently, it can be considered an alternative to the media traditionally used for the studied halophilic bacteria.

MOLECULAR IDENTIFICATION OF Pseudoterranova azarasi LARVAE IN COD (Gadus sp.) SOLD FOR HUMAN CONSUMPTION IN BRAZIL

Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8 % with Pseudoterranova azarasi, which belongs to the Pseudoterranova decipiens species complex. The risk of allergy when consuming dead larvae in salted fish is not well known and should be considered.

Determinação de atividade de água, umidade e sal em peixes salgados e secos importados

Brazil is a major importer in the world salted fish trade. The sale of these products must meet the established standards, based mainly on the salt and moisture levels. The aim of this study was to analyze the salt and moisture levels in imported Atlantic cod and Pacific cod, and in the dried salted fish Ling, Zarbo and Saithe, which are not classified as cod since they do not belong to the genus Gadus. The water activity was also analyzed, which could be a useful parameter to determine the quality of salted fish.The results showed that the legal limits for salt were much lower than the values found in the analyses. The moisture contents established for the category of salted fish, as determined by the Portuguese legislation, were more reliable. We suggest the inclusion of the water activity as a parameter for the evaluation of these products.

La estructuración del espacio urbano y productivo de Gadir durante la fase urbana clásica: Cambios y perduraciones

La reafirmación del modelo político-administrativo ciudadano tras la fase arcaica colonial abre una nueva etapa de prosperidad en la antigua fundación tiria. El esplendor de Gadir en el s. V a.C. se refleja en los textos clásicos y en los hallazgos arqueológicos y, sin embargo, nuestros conocimientos sobre el desarrollo histórico de la ciudad de época púnica son muy limitados. El horizonte arcaico comienza a esclarecerse tras los hallazgos del Teatro Cómico que han sacado a la luz los restos de la fundación tiria y, sin embargo, la ciudad posterior continúa siendo una gran incógnita. ¿A qué lugar se traslada la población una vez que se abandona el asentamiento primitivo? ¿Quiénes son los individuos enterrados en los excepcionales sarcófagos antropoides? ¿Qué relación jerárquica existe entre el asentamiento insular y los situados en tierra firme? ¿Qué papel jugó la industria y comercialización de las salazones? Los interrogantes planteados son múltiples y no hacen más que evidenciar la incapacidad del paradigma tradicional para explicar el desarrollo histórico de la Gadir postcolonial y la necesidad de buscar nuevos modelos interpretativos.

Fisheries Department Annual Report 1969

During the year 1969, the fishing industry maintained a rate of increase that had been witnessed in the three previous years. The total catch landed was estimated at 125300 metric tons, valued at shs 130,500,000/-at the lakeside,and about shs 260,000,000/-in the retail market. This was an increase of 16,900 metric tons over the 1968 figure. The largest increases again came from the Lake Kyoga area, where the Nile Perch and the introduced Tilapia species are still expanding. Large numbers of fishermen from other regions (i.e. from Lake Victoria) moved to Lake Kyoga where catches were high and remunerative. This intensified fishing on this lake, resulting in the high figure of catches recorded. As in the previous year, there was a marked increase in the use of large-mesh gill-nets for catching Nile Perch and Tilapia. Individual Tilapia nilotica of up to 5 kg were quite common, and Nile Perch weighing over 50 kg were also regularly taken. The marketing and distribution side of the industry was as active as ever: 87 people took out specific licences, and 640 fishmongers were licensed by different urban authorities. Elsewhere in the Districts, 7,950 fishmongers were licensed. Host of the fish landed was consumed within Uganda and exports accounted for dnly a very small fraction of the market, mainly composed of frozen fiilets to Kenyai and salted fish to the Republic of the Congo. Kampala market was the most important one, serving also as a central market from where fishmongers bought fish for distribution to rural areas.

Lusitanian Amphorae on Western Mediterranean Shipwrecks: Fragments of Economic History

Shipwrecks constitute a primary source for the study of the ancient economy. In this paper, we will highlight some of those whose cargo contained amphorae of Lusitanian production. These are of the utmost importance for understanding the navigation routes and the Lusitanian fish products export routes in the western Mediterranean.

STUDIES ON THE QUALITY AND PROCESS CONTROL FACTORS DURING THE PRODUCTION AND STORAGE OF SALTED DRIED FISH PRODUCTS

In this study the quality and process control factors during the production and storage of salted dried fish products. The study reveals that quantity of dry fish production in the state is decreasing and dry fish processing industry should be encouraged by central and state governments. The dry and wet salting may be carried out to a period of 4 to 8 hours respectively and time may depend on temperature, size, and concentration of medium. Demand is an unavoidable factor for sale of fish. The packed dry salted lots kept at room temperature are useful only for 20 days. The refrigerator- stored lots had more storage life and nutritional content are good up to 3 months. The cold storage stored dry salted lot had more storage life than the wet salted lot. The use of preservatives in salting is encouraged to reduce pH. The low temperature preservation maintains the nutritional value and quality for long period. It further encourages the labeling of nutritional value of dry fish as in tinned products.

Physicochemical and microbiological changes in dried small-spotted catshark (Scyliorhynus canicula): developing an alternative shark-based salted-dried seafood product

A relatively high proportion of harvested seafood is still wasted due to spoilage, particularly in developing countries, or because they are by-catches or have little economic value, seemingly related to inherent problems linked to unattractive color, flavor, texture, small size, and high-fat content. Thus, many fish and seafood species are still underutilized.

[the Use Of Fish On Buccal Smear To Investigate Mosaicism With A 45,x Cell Line: Study On Healthy Men And Patients With Disorders Of Sex Development].

To verify whether fluorescence in situ hybridization (FISH) of cells from the buccal epithelium could be employed to detect cryptomosaicism with a 45,X lineage in 46,XY patients. Samples of nineteen 46,XY healthy young men and five patients with disorders of sex development (DSD), four 45,X/46,XY and one 46,XY were used. FISH analysis with X and Y specific probes on interphase nuclei from blood lymphocytes and buccal epithelium were analyzed to investigate the proportion of nuclei containing only the signal of the X chromosome. The frequency of nuclei containing only the X signal in the two tissues of healthy men did not differ (p = 0.69). In all patients with DSD this frequency was significantly higher, and there was no difference between the two tissues (p = 0.38), either. Investigation of mosaicism with a 45,X cell line in patients with 46,XY DSD or sterility can be done by FISH directly using cells from the buccal epithelium.
