In the Mediterranean region, fish is a common cause of food protein-induced enterocolitis syndrome (FPIES) in children. No laboratory tests specific to FPIES are available, and oral food challenge (OFC) is the gold standard for its diagnosis and testing for achievement of tolerance. Children with FPIES to fish are usually advised to avoid all fish, regardless of the species. Fish are typically classified into bony and cartilaginous, which are phylogenetically distant species and therefore contain less cross-reacting allergens. The protein β-parvalbumin, considered a pan-allergenic, is found in bony fish, while the non-allergenic α-parvalbumin is commonly found in cartilaginous fish. Based on this difference, as a first step in the therapeutic process of children with FPIES caused by a certain fish in the bony fish category (i.e., hake, cod, perch, sardine, gilthead sea bream, red mullet, sole, megrim, sea bass, anchovy, tuna, swordfish, trout, etc.), an OFC to an alternative from the category of cartilaginous fish is suggested (i.e., blue shark, tope shark, dogfish, monkfish, skate, and ray) and vice versa. Regarding the increased mercury content in some sharks and other large species, the maximum limit imposed by the European Food Safety Authority (EFSA) for weekly mercury intake must be considered. An algorithm for the management of fish-FPIES, including alternative fish species, is proposed.

Cultured Fish

In intensive fish rearing system, fish are kept in high densities and their chance to be exposed to micro organisms that can cause infection, such as bacteria, parasites or viruses, is very high. Under these circumstances, the problem of infectious diseases is becoming very important and has significant results. Bacterial and viral diseases of the cultured fish species have led to high mortalities and have decreased the income of the fish farming industries. There are many examples in the Mediterranean Sea, in the production of sea bream (Spams aurata), sea bass (Dicentrarchus labrax) and many other cultured fish species. In the last years, this production has been followed by important outbreaks of known diseases and also by the appearance and identification of new ones. Until recently, for the control of the bacterial and parasite diseases, only antibiotics and chemical products were used that often demonstrated side effects, like residues in the fish muscle, development of resistance to the antibiotics and environmental pollution. Moreover, for the viral diseases, for which there is no treatment, the onset of the disease usually demands the destruction of the infected population. All the above, showed that there was a need to find methods to prevent the infection of the fish populations and this led to the development of vaccines. At the beginning, vaccines were produced only for the most common diseases and were easy to prepare bacterial vaccines, for example for vibriosis, furunculosis and red mouth disease (ERM). Nowadays, the production of new and more effective vaccines has began, even for diseases that are caused by viruses, like the subunit vaccines, the live recombinant and the genetic vaccines.

The aim of this study was to determine the monthly price changes of cultured fish which were offered for sale in retail fish outlets in Sinop, Turkey. The fish enterprises were determined by stratified sampling method. The enterprises were grouped as I (the most), II (moderate) and III (the least) according to the amount of their sales. Each group was represented by two different fish enterprises. During the study, prices of the same fish species were obtained twice a month at the same time of the day and the data were calculated as average ± SD. The differences between the groups were determined by one-way variance analysis (ANOVA) and the price relation level between species was evaluated by the correlation analysis using IBM SPSS 21 Statisticssoftware. It was determined that sea bream (Sparus aurata), sea bass (Dicentrarhus labrax), rainbow trout (Oncorhyncus mykiss) (portion size and kilos) and salmon (Salmo salar) (import) were offered for sale in fish markets as cultured fish species. These species were sold during the fishing ban period (April-August). They were also sold starting from September when the fishing ban period ended up and the fishery products were at their lowest. For all the species, the differences between the pricesice were not significant between the sampled enterprises. The average values of the current prices were higher than that of 2008-2013 period. A negative strong relation was determined between the rainbow trout and the salmon.

Abstract Background: Telemetry applied to aquatic organisms has recently developed greatly. Physiological sensors have been increasingly used as tools for fish welfare monitoring. However, for the technology to be used as a reliable non-invasive welfare indicator, it is important that the tagging procedure does not disrupt fish physiology, behaviour and performance. In this communication, we share our medium-term data on stress physiological profile and growth performance after tag implantation in two important marine fish species for European aquaculture, the sea bream ( Sparus aurata ) and the European sea bass ( Dicentrarchus labrax ). Results: Blood samples after tag implantation (46 days for the sea bream and 95 days for the sea bass) revealed no differences between tagged and untagged fish in cortisol, glucose and lactate levels, suggesting that the tag implantation does not induce prolonged stress in these species. Moreover, the specific growth rates were similar in the tagged and untagged fish of both species. Conclusion: Tag implantation does not have medium-term consequences for the stress physiology and growth performance of these two marine fish species in a controlled environment. These observations support the use of accelerometer tags as valuable tools for welfare monitoring in aquaculture conditions, as they do not affect the fish’s welfare and health. This study also shows that tagged fish can be sampled during experiments and considered a representative portion of the population, as they display growth and physiological parameters comparable to those of untagged fish.

Intensive Rearing

Published data on growth and pathology of the fish species: Mugil cephalus (mullet) and Acipenser gueldestaedi (sturgeon), under intensive culture, is limited. In particular, data on dietary requirements is non-existing. For the artificial feeding of these fish, other feeds originally prepared for other cultured fish species are used (trout and/or sea bass, sea bream pelleted feeds). Mugil cephalus is very tolerant to intensive rearing and the main problem observed was recurrent infections by Chilodonella sp. Mugilids reared in lagoons are infected with a variety of parasites, but these do not cause problems and mortality. Acipenser gueldestaedi is a very desirable fish for rearing, because of the fast growth rate, the good digestibility of food, even with no specific diets and the ability to be cultured under different systems. Furthermore, it has a wide temperature tolerance, it is very tolerant to stress and the mortality at fish> 5cm is less than 5%. Disease experiences from rearing sturgeon are reported mainly from N. America and concern viral infections. In Greece, Acipenser gueldestaedi seems to be very susceptible to both Noda virus and spinal deformities after the weight of 500g. Fish in open flow systems started to show skeletal abnormalities with increasing prevalence. Histopathology investigations, both in Greece and Canada, were inconclusive as to the aetiology of these skeletal deformities. These could not be proved to be associated with the feed of the fish. These deformities have been observed before in cultured sturgeon, but they are not yet fully investigated. At a later stage, fish cannot swim properly, do not feed and soon succumb to secondary infections by Aeromonas hydrophila.

Food Challenges

Background: Oral food challenges (OFC) in food protein‐induced enterocolitis syndrome (FPIES) are performed to confirm a diagnosis, test for development of tolerance, and find safe alternatives. Objective: We aimed to define OFC outcomes and identify safer test strategies. Methods: OFCs performed in children with FPIES over a 5-year period were reviewed. Results: A total of 160 OFCs were performed in 59 children (median age, 2.3 years). The most commonly tested foods were hen's egg, fish, and cow's milk. Sixty-six OFC results (41.3%) were positive. Twelve (18.2%) reactions were mild, 18 (27.3%) were moderate, and 36 (54.5%) were severe. Intravenous fluid, ondansetron, and corticosteroids were administered in 83.3, 72.7, and 66.7% of the patients, respectively; one patient required hospitalization. A reaction was most likely with fish (odds ratio [OR] 2.878 [95% confidence interval {CI}, 1.279‐6.473]; p = 0.011), and least likely with cow's milk (OR 0.268 [95% CI, 0.082‐0.872]; p = 0.029). Of the 36 OFCs with egg yolk, 23 patients had a failed OFC, and of the 17 OFCs with egg white (all tolerant to egg yolk), only 2 patients had a failed result. Interestingly, two patients tolerated baked whole egg but not egg yolk. In cow's milk FPIES, two patients could consume fermented milk but not fresh milk. Of the 11 patients with anchovy-triggered FPIES, 6 tolerated sea bass, and 5 tolerated trout, whereas 4 patients with sea bass FPIES tolerated trout. Conclusion: The search for alternative food species, processing, or subdivision of a trigger food is common practice in FPIES, which reflects the expectations of children and their families. The experience gained can be put into practice and will contribute to the understanding of the disease mechanism.

Abstract Major part of healthy human diet consist of marine fish and seafood products. And it is not surprising that there are numerous studies based on metal accumulation in various fish species. Fish may also be used for heavy metal monitoring programs of marine environments due to their easy sampling, sample preparation and chemical analysis. Concentrations of lead, cadmium, nickel, copper, manganese, zinc, iron, chromium, total mercury and total arsenic were determined in edible part of two commercially valuable fish Greek aquaculture species European sea bass (Dicentrarchus labrax) and gilthead sea bream (Sparus aurata) purchased from Bulgarian market during 2011. The concentration of metals was measured by atomic absorption spectrophotometry (AAS). The concentration of the heavy metals in examined fish species ranged as follow: Pb 0.008 - 0.013; Cd 0.0017 - 0.022; Ni 0.007 - 0.012; Cu 0.054 - 0.115; Mn 0.043 - 0.09; Zn 0.14 - 0.15; Fe 0.17 - 0.19; Cr 0.05 - 0.07; Hg 0.11 - 0.13; As 1.6 - 1.8 mg kg-1 wet weight, respectively. The concentration of the heavy metals obtained from this study is compared with the results of a Black Sea bluefish (Pomatomus saltatrix) caught during the same year. The concentration of metals was significantly affected by the sampling site and fish species. Difference in the heavy metal concentration between European sea bass, gilthead sea bream is observed for Cu, Mn, Zn and Fe. Although, the heavy metals in the edible parts of the investigated fish were in the permissible safety levels for human uses.

Abstract Background Recently, telemetry applied to the aquatic organisms had a great development. Progressively, physiological sensors were used, as tools for fish welfare monitoring. However, it is important that tagging procedure does not disrupt fish physiology, behavior and performances to be used as a reliable non-invasive welfare indicator. In this communication, we share our mid-term data about stress physiological profile and growth performances following tag implantation in two important marine fish species of the European aquaculture, sea bream (Sparus aurata) and European sea bass (Dicentrarchus labrax). Results Mid-term blood samples post-tag implantation (46 days for sea bream and 95 days for sea bass) revealed no difference between tagged and untagged fish in the cortisol, glucose and lactate levels, suggesting that the tag implantation does not induce prolonged stress in these species. Moreover, the specific growth rate was similar for tagged and untagged fish in both species. Conclusion As a conclusion, the tag implantation does not induce mid-term consequences on the stress physiology and the growth performances of these two marine fish species under controlled environment. These observations first support accelerometer tags as useful tools for welfare monitoring in aquaculture condition because they do not affect the welfare and health of implanted fish. Secondly, this study shown that tagged fish can be sampled during experiments and be considered as a representative portion of the population, displaying similar growth and physiological parameters compared to untagged fish.
