Consumers’ Perceived Differences between Wild and Farmed Fish: A Survey Study in Turkey

This study investigated consumers’ motivations and perceptions of fish obtained from different production methods, namely wild or farmed. Data were collected from 526 consumers via face-to-face interviews in the seven regions of Turkey. A logistic regression model was designed for the consumers of different fish production methods. Results of the study demonstrate that consumers perceive wild and farmed fish differently. Furthermore, consumers have different perceptions of the following factors that also effect consumption: convenience, variety, origin, confidence, accessibility, freshness, and reliability.     

Effects of dietary Bergamot (Citrus bergamia) peel oil on growth,haematology and immune response of European sea bass (Dicentrarchus labrax) juveniles

The aim of the present study was to evaluate the effects of essential oil extracted from bergamot (Citrus bergamia) peel on growth performance and health status of European sea bass juveniles (5.10 + 0.05 g). Test diets supplemented with 0.0%, 0.5%, 1.0% and 2.0% bergamot peel oil (BPO₀, BPO_0.5, BPO₁ and BPO₂) were fed to experimental fish for 60 days. At the end of the experiment, the best growth performance was obtained in the BPO_0.5 and BPO₁ groups (p < .05). No significances were found for haematological parameters including red blood cell count, haematocrit and haemoglobin concentration at the end of the feeding experiment. There were significant differences between the total protein, cholesterol, alkaline phosphatase and glutamic oxaloacetic transaminase (p < .05) between the BPO0.5 and BPO1 supplemented groups and the control group with no BPO addition. The addition of BPO showed significant differences in immune parameters such as lysozyme activity, total myeloperoxidase content, superoxide dismutase and glutathione peroxidase activity between BPO₀ and BPO supplemented groups (p < .05). It might be concluded that dietary addition of 0.5%‐1% BPO could increase the growth performance and feed utilization with improved health status in sea bass juveniles.
