“…Numerous research has been carried out on the substitution of fish oil by vegetable oils within compounded fish feeds, using fishmeal-based diets, high-energy diets or plant-protein rich diets and results were always promising. Linseed oil (LO) is among the most common vegetable oils examined, singly or in combination, in researches for fish feed production including gilthead seabream (reviewed by Nasopoulou and Zebatakis, 2012), whereas sunflower oil (SFO) was not previously evaluated for the species. However, reports on using sunflower oil in feeds for Atlantic salmon (Salmo salar) (Torestensen et al, 2000;Bransden et al, 2003;Menoyo et al, 2007) and European seabass (Dicentrarchus labrax) (Yieldiz and Sener, 2004) are promising.…”

“…These results are in accordance with those earlier reported for European seabass, that LAO was found in higher levels in SFO-or soybean oil (SBO)-fed fish than in the other groups (Yieldiz and Sener, 2004). However, virtually all studies on this species reported changes in the tissue fatty acid composition, most notably a rise in n-6 series fatty acids (reviewed by Glencross, 2009;Nasopoulou and Zebatakis, 2012). This indicated that gilthead seabream have limited capabilities to convert LOA and α-LNA into EPA, DHA and ARA.…”

-A feeding trial was conducted to define the optimal mixtures of either sunflower oil (SFO) or linseed oil (LO) with fish oil (FO), in fish meal (FM) based diets for gilthead seabream (Sparus aurata) fingerling, without significant effect on fish performance, fatty acid composition and liver structure. The trial lasted nine weeks with 420 fish (∼4.0 g) testing seven isonitrogenous (∼48% CP) and isolipidic (∼18% L) diets contained three incremental inclusions of either SFO or LO (40, 48, 56 g kg −1 ) and the only-fish oil control (CTRL) diet. Results showed that the combination of 32 g fish oil plus 48 g of either SFO or LO kg −1 diet as the lipid source had performed the best among all. Fatty acid (FA) composition of muscle lipids evidenced that specific fatty acids were selectively retained or utilized. Diet induced-changes in hepatic morphology with vegetable oil inclusion level were further described. Linolenic acid (α-LNA, n-3) had led to less pronounced steatosis symptoms than linoleic acid (LOA, n-6) in liver cells. This study provides sound support for the use of preferably sunflower oil then linseed oil as a complementary lipid resource (48 g kg diet −1 ) with marine fish oil in gilthead seabream fingerling diets. Therefore, represents novel data on the potential of using sunflower oil (SFO) as a possible dietary partial substitute of fish oil for the species.

“…In addition, the progressive growth of aquaculture industry, as well as using energy-dense diets in carnivorous fish production have further exacerbated this problem [89,134]. If EFA requirements are met, a large fraction (60-75%) of FO can be substituted with vegetable oils (VO) or terrestrial animal fats (i.e., beef tallow, poultry fat, lard) without significantly affecting growth and FCR [89,135,136]. Regarding sparids, the maximum replacement of dietary FO with different VO sources has been reported to be about 70% in S. aurata [137]; 80% in A. schlegeli [138]; and 100% in D. puntazzo [139], P. major [140] and P. bogaraveo [76] (Table 10).…”

Silvery-black porgy (Sparidentex hasta) is recognized as one of the most promising fish species for aquaculture diversification in the Persian Gulf and the Oman Sea regions. In this regard, S. hasta has received considerable attention, and nutritional studies focused on establishing the nutritional requirements for improving diet formulation have been conducted during recent years. Considering the results from different dose-response nutritional studies on macronutrient requirements conducted in this species, it can be concluded that diets containing ca. 48% crude protein, 15% crude lipid, 15% carbohydrates and 20 KJ g −1 gross energy are recommended for on-growing S. hasta juveniles. In addition, the optimum essential amino acid profile for this species (expressed as g 16 g N −1 ), should be approximately arginine 5.3, lysine 6.0, threonine 5.2, histidine 2.5, isoleucine 4.6, leucine 5.4, methionine + cysteine 4.0 (in a diet containing 0.6 cysteine), phenylalanine + tyrosine 5.6 (in a diet containing 1.9 tyrosine), tryptophan 1.0 and valine 4.6. Moreover, the optimum dietary n-3 long chain polyunsaturated fatty acids and soybean lecithin are recommended to be 0.8% and 6%, respectively. The maximum replacement of fish meal with soy protein is recommended to be between 16.5% and 27.3%. In addition, different vegetal oil sources are also recommended for partial and almost complete replacement of fish oil in diets. Although the nutritional requirements in terms of macronutrients have been established under laboratory conditions, the analysis of the available literature indicate that future studies need to be conducted using a more holistic approach under intensive farming conditions in which different nutrients or additives need to be tested under different rearing conditions for refining nutrient requirements in this species.

“…In the next ten years, fish oil production may not cover the total necessary quantity for aquaculture. In order to reduce dependence on fish oil, significant breakthroughs have occurred over the past few years in replacing it with plant oils and all these papers have been recently critically evaluated (Nasopoulou & Zabetakis, 2012). Regarding the use of OP in fish feeds, the relevant reports are presented here.…”

“…Currently, one million tonnes of fish oil are produced on an annual basis (Pike & Jackson, 2010), while 40% and 60% of the global production of fish meal and fish oil, respectively, are used in aquaculture (Nasopoulou & Zabetakis, 2012). Salmonid diets alone consumed over 55% of the fish oil used by the aquaculture sector in 2006 (Jackson, 2007).…”

Olive Pomace (OP) is the main agricultural by-product of olive industry; because of its nature, it is a major environmental issue for all the olive-producing countries. Research on the waste-management issues of OP has been active over the last decade. The data presented in the present review suggest that OP could be exploited as an alternative dietary lipid source in compounded fish feeds resulting in the formulation of functional fish feeds and aquacultured fish according to the EU legislation (EC 1924(EC /2006. Moreover OP can also be used in agriculture by inclusion in animal feeds without attenuating animal performance and meat quality.In this review, all the latest results on the in vitro and in vivo studies regarding the usage of OP in fish and animal feeds are evaluated and the environmental and nutritional implications for aquaculture and agriculture industries are presented.
