“…The difference in fat and protein content might be because of different catching locations as environmental conditions might cause dramatic variations among the same species living in different locations. Although the results obtained in this study are in agreement with fluctuations reported by Bandarra et al (2001), in this study considerably higher fat and lower protein contents were observed in horse mackerel. Other components including water and mineral are in good agreement with those reported previously by these researchers.…”

“…The results indicated that the protein content of horse mackerel was around 13% although it is higher in November and December. The average protein content for six months was found to be 14.78% in horse mackerel, which was lo wer than that reported by Celik (2008), Bandarra et al (2001) and Osako et al (2002). These researchers have found higher protein amounts in horse mackerel and their results were 18.…”

Nutritional composition of four marine fish species (horse mackerel, garfish, golden mullet, and shad), constitute to 25% of the total marine fish production in Turkey, was examined monthly during the catching season (October through M arch). Among fish species studied; horse mackerel, garfish, and golden mullet revealed increases in protein up to 35% until December and then a dramatic decrease in January up to 30%. Fat content was also found increasing until December in horse mackerel and garfish, and a sudden decrease was observed in January. Protein content varied between 13.0-19.8% among the species studied on fresh weight basis. The lowest protein content was found to be in horse mackerel, 14.8% and the highest in garfish, 16.9%. The results showed that shad gives the highest energy upon consumption due to high fat content, throughout four months from December to M arch. Fat content of garfish and golden mullet was found to be low compared to other species studied. Consequently, energy values of these two species were low, 479 and 460 kj/100 g, respectively .Keywords: Proximate composition, shad, garfish, horse mackerel, golden mullet. Karadeniz'deki Bazı Balık Türlerinin Biyokimyasal Kompozisyonundaki Mevsimsel Değişimler ÖzetBu çalışmada, Türkiye'deki toplam deniz balıkçılığı üretiminin yaklaşık %25'ini oluşturan dört balık türünün (istavrit, zargana, altınbaş kefal ve tirsi) besin kompozisyonu avlanma sezonunda (ekim ve mart ayları arasında) altı ay boyunca aylık olarak incelenmiştir. Çalışılan balık türleri arasında; istavrit, zargana ve altınbaş kefalin protein miktarı Aralık ayına kadar %35'e kadar artmış ancak daha sonra ocak ayında %30'a kadar ciddi bir düşüş göstermiştir. İstavrit ve zargananın yağ miktarı da aralık ayına kadar artmış ancak ocak ayında ciddi bir düşüş göstermiştir. Çalışılan türlerin protein miktarı aylara göre t aze balık ağırlığının %13 ve %19,8'i arasında değişmiştir. En düşük ve en yüksek ortalama protein miktarı sırasıyla %14,8 ile istavritte ve %16,9 ile zarganada tespit edilmiştir. Elde edilen sonuçlar, aralık ayından mart ayına kadar dört ay boyunca, yüksek yağ miktarı nedeniyle tirsinin en yüksek enerjiyi vereceğini göstermektedir. Zargana ve altınbaş kefalin yağ miktarının çalışılan diğer türlere göre daha düşük olduğu belirlenmiştir. Buna bağlı olarak, bu iki türün enerji miktarının düşük ve sırasıyla 479 ve 460 kj/100 g olduğu hesaplanmıştır.Anahtar Kelimeler: Biyokimyasal kompozisyon, tirsi, zargana, istavrit, altınbaş kefal.

“…Seasonal variability in PAH levels in tissues has been reported in several studies associated with an increase in the exposure or/and linked to biological factors such as the reproductive cycle of the organisms (Baumard et al, 1999;Webster et al, 2002). Considering that November follows the season where the fat availability in the Portuguese coast is higher (Bandarra et al, 1997(Bandarra et al, , 2001, associated with a rise in sea temperature that favors higher rates of food intake (Mangold and Boletzky, 1973), the higher concentrations of Σ PAHs are expected due to their lipophilicity. Previous studies reported no evidence of energy reserves and lipid transfer between the digestive gland and the gonad with the reproductive status in octopus so this factor was probably not influencing the PAH concentrations observed (Quetglas et al, 2011;Rosa et al, 2004b), but instead, fat availability and food intake were influential.…”

Among organic pollutants existing in coastal areas, polycyclic aromatic hydrocarbons (PAHs) are of great concern due to their ubiquity and carcinogenic potential. The aim of this study was to evaluate the seasonal patterns of PAHs in the digestive gland and arm of the common octopus (Octopus vulgaris) from the Northwest Atlantic Portuguese coast. In the different seasons, 18 PAHs were determined and the detoxification capacity of the spe-cies was evaluated. Ethoxyresorufin O-deethylase (EROD) and ethoxycoumarin O-deethylase (ECOD) activities were measured to assess phase I biotransformation capacity. Individual PAH ratios were used for major source (pyrolytic/petrogenic) analysis. Risks for human consumption were determined by the total toxicity equivalence approach. Generally, low levels of PAHs were detected in the digestive gland and in the arm of octopus, with a predominance of low molecular over high molecular weight compounds. PAHs exhibited seasonality in the con-centrations detected and in their main emission sources. In the digestive gland, the highest total PAH levels were observed in autumn possibly related to fat availability in the ecosystem and food intake. The lack of PAH elimina-tion observed in the digestive gland after captivity could be possibly associated to a low biotransformation capac-ity, consistent with the negligible/undetected levels of EROD and ECOD activity in the different seasons. The emission sources of PAHs found in the digestive gland varied from a petrogenic profile observed in winter to a pyrolytic pattern in spring. In the arm, the highest PAH contents were observed in June; nevertheless, levels were always below the regulatory limits established for food consumption. The carcinogenic potential calculated for all the sampling periods in the arm were markedly lower than the ones found in various aquatic species from different marine environments. The results presented in this study give relevant baseline data for environmental monitoring of organic pollution in coastal areas.

Seafood is an excellent source of metabolically essential proteins, vitamins, trace elements and polyunsaturated fatty acids. There is a rising awareness of the beneficial role of fish and other marine foods in human nutrition. The knowledge regarding the nutritional significance of fish in counteracting the malnutrition and age-associated chronic diseases are relatively scanty. In this present study, an attempt has been made to examine the proximate composition, amino acid profile and fatty acid composition of small pelagic fishes (sardine, mackerel and anchovy) available in Indian south-west coast waters. The biochemical parameters were determined using standard experimental protocols. The low value small pelagic fishes are found to be rich sources of ω-3 Fatty acids [eicosapentaenoic acid (EPA) & docosahexaenoic acid (DHA)], which are very much essential for the development of brain and heart tissues. Sardine and mackerel possess all the essential and non-essential amino acids in a balanced proportion capable of ameliorating the protein deficiency disorders. The non-protein amino acid taurine essential for various physiological functions was also found to be present in rich quantities in small pelagic fishes. Presence of sulphur containing amino acids cysteine and methionine and high histidine content adds functionality to the nutritional value of small pelagic fish protein. Anchovies and sardine are valuable sources of calcium, which can effectively be used to combat calcium deficiency in children. The result of the present study has indicated that small pelagic fishes [sardine, mackerel and anchovy] are potential sources of attenuating malnutrition-related diseases and age-associated disorders.
