Influence Of Feeding Frequency On Feed Intake, Growth Performance And Nutrient Utilization In European Sea Bass (Dicentrarchus Labrax) Fed Pelleted Or Extruded Diets, Derya Güroy, Emrah Deveci̇ler, Betül Kut Güroy, Ahmet Adem Teki̇nay
Turkish Journal of Veterinary & Animal Sciences
In an 83-day-nutrition trial, effects of feed production technique and feeding frequency on feed intake, growth and nutrient utilization were determined in European sea bass (Dicentrarchus labrax). Three thousand six hundred fish (170 ± 2.6 g) were randomly allocated to experimental sea cages (approx. 5800 l) according to a 2 x 2 experimental plan [2 processing techniques: steam pelleted diet (P) vs. extruded diet (E); 2 feeding frequencies: twice (2) vs. 3 times (3)]. The P3 group consumed significantly (P < 0.05) more feed than the fish fed extruded diets, irrespective of feeding frequency. Growth rates of all groups did not display any significant difference (P > 0.05) in terms of final weight (FW) or specific growth rate (SGR), although there was a decreasing trend in final …
The Effect Of Emamectin Benzoate In The Control Of Lernanthropus Kroyeri (Van Beneden, 1851) (Lernanthropidae) Infestations In Cultured Sea Bass, Dicentrarchus Labrax (Linnaeus, 1758), Erol Tokşen, Haşmet Çağirgan, Tansel T. Tanrikul, Hülya Saygi
The Effect Of Emamectin Benzoate In The Control Of Lernanthropus Kroyeri (Van Beneden, 1851) (Lernanthropidae) Infestations In Cultured Sea Bass, Dicentrarchus Labrax (Linnaeus, 1758), Erol Tokşen, Haşmet Çağirgan, Tansel T. Tanrikul, Hülya Saygi
Turkish Journal of Veterinary & Animal Sciences
Five different dose groups were formed to evaluate the efficacy of emamectin benzoate as a treatment for Lernanthropus kroyeri (van Beneden, 1851) infestation in cultured sea bass Dicentrarchus labrax (L.). Emamectin benzoate was administered in-feed at doses of 0 (control), 10, 25, 50, and 100 µg kg^{-1} biomass day-1 for 7 consecutive days. Parasites were counted on days 7, 14, and 21, and comparisons were made to untreated control fish. Seawater temperature was 16-16.5 °C. Treatment with emamectin benzoate was effective against larval and mature stages of L. kroyeri. The number of L. kroyeri in the control fish increased by …

Examination Of Genetic And Morphologic Structure Of Sea-Bass (Dicentrarchus Labrax L., 1758) Populations In Turkish Coastal Waters, Deni̇z Ergüden, Cemal Turan
Turkish Journal of Veterinary & Animal Sciences
In this study genetic and morphologic structure of the sea-bass, Dicentrarchus labrax, in Turkish coastal waters were studied. Total 120 individuals were sampled in equal numbers from the Black, Marmara, Aegean and North-eastern Mediterranean Seas. In genetic analyses, four-enzyme systems (G3PDH*, ME*, MDH*, PGI*) were assayed, representing 9 loci (G3PDH-1*, G3PDH-2*, MDH-1*, MDH-2*, MDH-3*, ME*, PGI-1*, PGI-2*, PGI-3*), 2 of which were polymorphic (G3PDH-2*, PGI-3*). Fisher's exact test revealed that there were no genetic differences between populations using 9 loci. Nei's genetic distance was 0.0001 between the Black Sea and Mediterranean samples. Genetic identity was also found to be 0.9999 …
The Effect Of Dietary Oils Of Vegetable Origin On The Performance, Body Composition And Fatty Acid Profiles Of Sea Bass (Dicentrarchus Labrax L., 1758) Juveniles, Mustafa Yildiz, Erdal Şener
The Effect Of Dietary Oils Of Vegetable Origin On The Performance, Body Composition And Fatty Acid Profiles Of Sea Bass (Dicentrarchus Labrax L., 1758) Juveniles, Mustafa Yildiz, Erdal Şener
Turkish Journal of Veterinary & Animal Sciences
Body fat composition and growth performance of sea bass juveniles fed with different kinds of vegetable oils instead of fish oil were studied. Feeding trials were carried out with 600 sea bass (Dicentrarchus labrax L.) juveniles with on initial live weight of 7.58 ± 0.13 g. Experimental feeds contained fish oil, soybean oil, sunflower oil, corn oil and olive oil. In the chemical analyses of the experimental feeds, total crude fat was 12.33 ± 0.24% and total crude protein was 57.42 ± 0.31%. According to fatty acid analyses EPA (7.57%) and DHA (11.91%) in the feed containing fish oil, linolenic …
The Effects Of Replacing Fish Oil With Vegetable Oils In Starter Feeds On The Liver Fat Composition Of Sea Bass (Dicentrarchus Labrax L., 1758), Mustafa Yildiz, Erdal Şener
The Effects Of Replacing Fish Oil With Vegetable Oils In Starter Feeds On The Liver Fat Composition Of Sea Bass (Dicentrarchus Labrax L., 1758), Mustafa Yildiz, Erdal Şener
Turkish Journal of Veterinary & Animal Sciences
The effects of replacing fish oil with soybean oil, sunflower oil, corn oil and olive oil in starter feeds on the vicerosomatic index, hepatosomatic index and liver fatty acid composition of the sea bass were studied. Juvenile sea bass (initial weight = 7.58 ± 0.13 g) were fed experimental diets for 75 days. The fish were then killed and liver samples were collected. The lowest total crude fat value (17.61%) was found in the fish fed the fish oil diet. The highest total crude fat value (34.30%) was found in the fish fed the olive oil diet (P < 0.05). Similarly, the fish fed the fish oil diet had the lowest hepatosomatic index value (2.08) and all the fish fed vegetable oils had similarly high hepatosomatic index values (P < 0.05). Likewise, vicerosomatic index values were lowest (9.06%) in the fish fed fish oil and highest in the fish fed soybean and other vegetable oils (P < 0.05). Fatty acid analyses showed that EPA and DHA from n-3 HUFA's in the fish fed the fish oil diet, linolenic acid (18:3n-3) and linoleic acid (18:2n-6) in the fish fed the soybean oil diet and oleic acid (18:1n-9) in the fish fed the olive oil diet were higher than in the fish fed the other diets.

Growth Performance, Body Traits And Fillet Composition Of The European Sea Bass (Dicentrarchus Labrax) Reared In Various Salinities And Fresh Water, O. Tufan Eroldoğan, Meti̇n Kumlu
Turkish Journal of Veterinary & Animal Sciences
The effects of various salinities and fresh water (FW) (0.4 ppt) on the growth performance, body traits and fillet composition of juvenile and young sea bass (Dicentrarchus labrax) in FW were investigated in two separate experiments in this study. In Experiment 1, following acclimation, sea bass juveniles (9.5 ± 0.5 g) were reared in 240-L fibreglass tanks (40 x 40 x 150 cm) for 90 days in five different treatments (FW, 10, 20, 30 and 40 ppt). The fish cultured in FW, 10 and 20 ppt grew better than those at 30 or 40 ppt (P < 0.05). Salinity did not affect the crude protein, lipid or ash content of the fish (P > 0.05). Yet, the dry …

The Anaesthetics Effects Of Quinaldine Sulphate And/Or Diazepam On Sea Bass (Dicentrarchus Labrax) Juveniles, Mahmut Yanar, Meti̇n Kumlu
Turkish Journal of Veterinary & Animal Sciences
In this study, the effects of an anaesthetic quinaldine sulphate (QS) and a muscle relaxant, diazepam (D), on sea bass (Dicentrarchus labrax) juveniles (8-9 g) were investigated. When used together with D, the anaesthetic effect of QS was significantly increased. The fish entered light anaesthesia at 15 ppm QS, as compared to 5 ppm QS + 1 ppm diazepam (D). Similarly, a deep anaesthesia level was reached at only 7.5 ppm QS + 1 ppm D as compared to 20 ppm of QS. The use of QS alone at high concentrations (7.5-25 ppm) increased mortality from 10% to 100%. No …
