Brama Brama) Fillets by Packaging Under a Vacuum-Skin System
Shelf life extension of Atlantic pomfret (Brama brama) fillets by packaging under a vacuum-skin system LIPID DETERIORATION DURING CHILLED STORAGE OF ATLANTIC POMFRET (Brama brama) Francisco Pérez-Alonso1, Cristina Arias2 and Santiago P. Aubourg1,* 1 Instituto de Investigaciones Marinas (CSIC) c/ Eduardo Cabello, 6 36208-VIGO (Spain) 2 Departmento de Parasitología Universidad de Vigo As Lagoas-Marcosende 36200-VIGO (Spain) * Correspondent: e-mail: [email protected] Fax number: +34 986 292762 Phone number: +34 986 231930 Running Title: Lipid deterioration in chilled pomfret Key Words: Atlantic pomfret, chilling, muscle zones, lipid damage, amine formation SUMMARY Lipid damage produced during Atlantic pomfret (Brama brama) chilled storage (up to 19 days) was studied. For it, free fatty acid (FFA) and conjugated diene (CD) formation, peroxide value (PV), thiobarbituric acid reactive substances and fluorescent compounds formation were measured in two different white muscle zones (dorsal and ventral). Comparison with volatile amine formation (total volatile base-nitrogen, TVB- N; trimethylamine-nitrogen, TMA-N) was carried out. A gradual lipid hydrolysis was observed in both zones along the whole experiment. CD and peroxides formation was important during the experiment; peroxides showed the highest value at day 15 in both zones, that was followed by a peroxide breakdown at day 19. Interaction of oxidized lipids with nucleophilic compounds present in the fish muscle led to a gradual fluorescence development during the storage time in both zones. Mean values of the lipid content showed to be higher in the ventral zone than in the dorsal one, although significant differences could not be detected (p<0.05). -
First Record of a Coregonid Fish Species, Coregenus Albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake Shared Between Turkey and Georgia
J. Black Sea/Mediterranean Environment Vol. 25, No. 3: 325-332 (2019) SHORT COMMUNICATION First record of a coregonid fish species, Coregenus albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake shared between Turkey and Georgia Sedat V. Yerli Department of Biology, Hacettepe University, SAL, Beytepe, Ankara, TURKEY Corresponding author: [email protected] Abstract The genus Coregenus (Salmoniformes: Salmonidae) was recently considered not to be represented in Turkey. European cisco or vendace, Coregonus albula (Linnaeus, 1758) was reported for the first time for Turkey in this article with fifteen samples in Aktaş Lake, Ardahan. This species should be added to the checklist of Turkish fish fauna. Turkish name is proposed as “Akbalık” for this species. Keywords: Coregonus albula, first record, Aktaş Lake, Kartsakhi, alkaline lake, Georgia, Turkey Received: 30.10.2019, Accepted: 26.11.2019 Vendace or European cisco Coregonus albula (Linnaeus, 1758) is a native species for northern Europe. Berg (1948) reported the distribution of this species its morphological measurements in the former USSR and adjacent countries. Froese and Pauly (2019) summarized the natural distribution of vendace as Baltic basin, several lakes of upper Volga drainage; some lakes of White Sea basin and North Sea basin east of Elbe drainage; anadromous in Gulf of Finland and marine in northernmost freshened part of Gulf of Bothnia between Finland and Sweden; in Lake Inari, northern Finland; lower Rhine (now extirpated). The vendace was introduced, intentionally in some countries in Europe and United States of America. Vendace was introduced in 1959, 1982-1987 in the Irtysh River Basin and in 1960-61 in Lake Balkhash in Kazakhstan (Mitrofanov and Petr 1999). -

Succinate Dehydrogenase Activity in Unembryonated Eggs, Embryonated Eggs, Miracidia and Metacercariae of Some Flukes
THE KURUME MEDICAL JOURNAL 1973 Vol.20, No.4, P.241-250 SUCCINATE DEHYDROGENASE ACTIVITY IN UNEMBRYONATED EGGS, EMBRYONATED EGGS, MIRACIDIA AND METACERCARIAE OF SOME FLUKES MINORU AKUSAWA Department of Parasitology, Kurume University School of Medicine, Kurume, Japan KYOKO SAITO Department of Chemistry, Nippon Veterinary and Zootechnical . College, Musashino, Tokyo, Japan (Received for publication December 3, 1973) The authors examined the activity of succinate dehydrogenase (SD) in Fasciola hepatica and Paragonimus westermani with the stages in develop- ment from cell division egg to metacercaria. As a result of this experiment, in the unicellular stages and miracidium stages of F. hepatica and P. wester- mani, a very slight SD activity was detected. However, in the miracidium formation stages of these flukes, the activity was very strong. Thus, it was clear that the reduction of methylene blue decreased suddenly from the highest value when metamorphosis occurred. It was suggested that respira- tory metabolism rises with the progress of development and ability to decolorize methylene blue in creases. In the metacercaria stages of F. hepatica, P. westermani, Metagonimus yokogawai, the ability to decolorize methylene blue was persistent, but it was not so strong. During the time, so called hibernation time, when metacercaria invades into final host, meta- cercaria keeps metabolism of respiration as low as possible, and saves consumption of energy for maintenance of life. Metacercaria has biological function for parasitism. Biological studies have been made on has been already found in some flukes the development of the flukes as speci- (Huang and Chu, 1962; Bryant and Wil- mens. Accordingly, all the life history liams, 1962; Barry et al., 1968; Hamaji- has been clarified in these flukes up to ma, 1972, 1973). -

Coregonus Maraena) Ecological Risk Screening Summary
Maraena Whitefish (Coregonus maraena) Ecological Risk Screening Summary U.S. Fish and Wildlife Service, April 2011 Revised, September 2014 and June 2017 Web Version, 09/14/2017 Image: E. Östman. Public domain. Available: http://eol.org/data_objects/26779416. (June 2017). 1 Native Range, and Status in the United States Native Range From Froese and Pauly (2017): “Europe: In the Baltic Sea: Swedish coast (including Bothnian Gulf, not in Gotland); in southern Baltic, extending from the Schlei to Gulf of Finland. Southeast North Sea Basin: Ems, Weser and Elbe drainages 1 and small rivers of Schleswig-Holstein and Denmark. Landlocked in several lakes in Poland, Sweden, and Russia.” Status in the United States From Neilson (2017): “Failed introduction.” “A shipment of 409 individuals from Lake Miedwie (formerly Madue Lake), Poland was stocked in Garnder Lake, Michigan in 1877 (Baird 1879; Todd 1983).” Means of Introductions in the United States From Neilson (2017): “Coregonus maraena, along with other species of Coregonus, was intentionally stocked as a food fish by the U.S. Fish Commission (Todd 1983). According to Baird (1879), 1,000 eggs of C. maraena were shipped from Poland to Michigan in 1877 and hatched in captivity at the State Hatching House in Detroit. A total of 409 of the young fish were stocked in Gardner Lake (Baird 1879; Todd 1983). Baird (1879) considered the stocking an experimental introduction of a European food fish.” Remarks From Neilson (2017): “There is much confusion regarding the identity of whitefish imported from Germany in the late 1800s by the U.S. Fish Commission, primarily due to the uncertain taxonomy and systematics of Coregonus (Kottelat and Freyhof 2007).
