“…This was unexpected and inconsistent with the known phenomenon that feed intake in fish is regulated to meet their energy requirement (Boujard and Médale 1994;Grisdale-Helland and Helland 1997;Gélineau et al 2001;Wang et al 2005). It may be suggested that in shi drum, dietary protein plays more important role in the regulation of feed intake instead of dietary lipid or energy.…”

Shi drum (Umbrina cirrosa L.) is regarded as a promising new candidate for Mediterranean mariculture but specifically formulated feeds are not yet available due to knowledge gaps in its basic nutritional requirements. Therefore, this study was carried out to determine the effects of dietary lipid levels on growth and feed utilization in shi drum (72.6 g average weight). Four isonitrogenic diets differing in dietary lipid levels between 10 and 19% (named 10L, 13L, 16L, and 19L, respectively) were fed to triplicate groups of fish for 8 weeks. Growth was not affected by treatment whereas feed efficiency was significantly deteriorated in fish fed diets containing lipid higher than 13%. Whole body dry matter and lipid contents were significantly higher in fish fed 19L compared with fish fed the 10L, while whole body protein, ash, and total carbon (C) were statistically unaffected by the dietary treatment. A significant increase in feed, lipid, energy, nitrogen (N), and carbon (C) intake was recorded in fish fed 16L and 19L when compared with 10L. Carbon/nitrogen (C/N) ratio was significantly higher in fish fed 19L than 10L. Moreover, the N and C losses significantly increased in fish fed 19L compared with 10L and 13L. It was concluded that high dietary lipid did neither had any protein-sparing effect nor other positive result, and diets for shi drum are not recommended to contain more than 13% lipid.

“…Previous studies on several species reported that the lipid content in fish muscles changes seasonally [35,36], and that cultured fish meat tends to contain more lipids [37][38][39]. A high-fat diet causes an increase in the lipid content of fish tissues [40][41][42], and short-term fasting causes an increase of lipid content in the muscle [43]. However, feeds with higher lipid content are more expensive.…”

Since post-harvest improvement of food quality depends on the pre-harvest stage, controlling food quality at the pre-harvest stage is being recognized as an important aspect of food processing technology. n-3 Long-chain polyunsaturated fatty acids (n-3 LCPUFAs) are considered important factors in the suppression of cardiovascular disease and development of the infant brain and visual functions. Fish meat generally contains a larger amount of n-3 LCPUFAs than meat from terrestrial animals, but the amount of n-3 LCPUFAs in fish meat depends on their dietary fatty acid intake. In order to supply n-3 LCPUFAs to consumers, we developed a finishing-up method, through a 4-day lysine-deficient diet feeding for rainbow trout (Oncorhynchus mykiss) meat. This 4-day lysine deficiency did not affect fish body weight, while significantly increased the total lipid content in the muscle tissue. In addition, docosahexaenoic acid and total n-3 fatty acid contents increased significantly in the meat throughout the 4-day finishing treatment. We concluded that the finishing-up method using short-term lysine-deficient diet feeding enables us to enrich fish meat with n-3 fatty acids for human consumption.

“…For the feeds used in feed nutrition to cause less pollution, the required nitrogenphosphorus balance must be provided depending on the fish species and age. In aquaculture, by meeting the optimum protein and energy requirements of fish, waste feeds and nutrient losses can be prevented [7]. Furthermore, eutrophication can be prevented with polyculture applications (sea fish and crustaceans) [4].…”

Aquaculture is a sector that involves agricultural activities aiming to meet the increasing animal food demand, contribute to balanced and healthy diet and reduce the hunting pressure on natural fish stocks. In aquaculture activities in sea, producers who are aware of the major role of obtaining an ecological balance in production regard coast utilization and environmental management as a part of production. Therefore, determination of environmental factors in production activities is highly important for sustainable aquaculture. The present study aims to determine the environmental risks and solution criteria in offshore aquaculture systems in Turkish seas. Environmental and social risks in production are collected under the main headings comprising nutrient and waste load in water, feeding, overuse of antibiotics and chemicals, fish escape, diseases, working conditions and common areas; solution criteria are collected under the main headings comprising ecosystem, water management, feed properties, legal procedure, chemical use, field management and occupational health and safety.
