Emerging Bacterial Pathologies in Mediterranean Mariculture
Aquaculture is emerging as the fastest growing food-producing industry in the world because of the increasing demand for food fish consumption. The intensive culture of fish has led to outbreaks of various bacterial diseases, causing economic losses to the aquaculture industry worldwide [1,2]. In the last years in the Mediterranean basin is registering a growing attention to some emerging bacterial fish pathogens. In particular Vibrio harvey, normally pathogen for crustaceans, molluscs and elasmobranchs, recently caused damage to the nervous system and septicemia in varying degrees of various fish species farmed.
Cytochrome P450 as a Biomarker for Pollutant Exposure in Aquatic Organisms
Abeer Abdel-Wahab Ibrahim Hassanin *
Monitors or early warning premeditate to identify and define areas of contamination could be extremely important in analysis of groundwater aquifers, surface water lakes, reservoirs, rivers, and oceanic systems. The need for early detection and assessment of the impacts of pollution in the aquatic environment has led to the development of biomarkers. A biomarker can be defined as a measurable response at any level of biological organization that can be related to an impact of contaminants.
Low-Cost, Specific and Sensitive Detection of Infectious Spleen and Kidney Necrosis Virus by Loop-Mediated Isothermal Amplification
Guangxin Liua, Zeming Lia, Peixiao Luoa, Liyue Liua, Junfa Yuana, Yang Zhoua, Muhammad Asima, Xueqin Liua*,Li Lina*
Infectious spleen and kidney necrosis virus (ISKNV) has caused high mortality of mandarin fish (Siniperca chuatsi) cultured in Asian countries. The current research priority is to develop a low-cost, rapid, specific and sensitive diagnosis method which can be widely in the fish farm.
Aquaculture and Fish welfare: Evidences for Fish Nociception
Carla Patrícia Bejo Wolkers*, Anette Hoffmann
The prominent increase in the use of fish as animal model for behavioral, pharmacological and physiological studies, as well as in aquaculture production chains, raises important questions about the welfare of these animals and the possibility of suffering.
Evaluation of Green Alga Ulva Pertusa as a Dietary Ingredient for Rabbitfish Siganus Canaliculatus Juveniles
Cuihong You, Wentao Zhang, Shuqi Wang, Christopher H.K. Cheng, Yuanyou Li*
The green alga Ulva pertusa has not been well used and their decomposition may result in heavy environmental pollution along the coast. This study aimed at evaluating the feasibility of using U. pertusa as a dietary ingredient for rabbitfish Siganus canaliculatus. Six formulated feeds with 32% of total protein and 8% of lipid but different levels of dried U. pertusa meal were prepared.
The Stress Response and Fish Welfare in Aquaculture
Monica Serra, Elisabeth Criscuolo Urbinati, Carla Patrícia Bejo Wolkers*
In aquaculture, fish can be submitted to several stressors. Besides the inevitable handling at transport, counting, reproduction, etc., which are acute stressors, day-to-day conditions as noises, deterioration of water quality, competition among fish, for example, can act as chronic stressors and be a challenge to fish’s welfare and health.
Estimation of Genetic Variation in Natural and Cultured Stocks of Swimming Crab (Portunus trituberculatus) Detected by ISSR Markers
Ling-Xiao Liu, Yun-Guo Liu*, Shi-Chao Xing*
Inter simple sequence repeat (ISSR) analysis was performed in order to evaluate the genetic diversity of natural and cultured samples of swimming crab Portunus trituberculatus. A group of 180 genotypes belonging to five natural samples, DY, WF, WH, QD, RZ and one cultured population, YT were screened using 13 different ISSR primers.
