“…This is in agreement to previous studies in African catfish (Ng et al, 2003) and hybrid tilapia (Han et al, 2013). DHA in the liver (6.35-0.85) were relatively higher than that of the feed (5.66-0.58) indicating there was a selective retention of the DHA (Mozanzadeh et al, 2016). This also indicates that when O. niloticus are fed diets with increasing PO levels, their ability to synthesize EPA and DHA from short-chain n-3 fatty acids such as ALA is reduced (Han et al, 2013).…”

This study was aimed at elucidating the effects of replacing fish oil (FO) with palm oil (PO) on tissue fatty acid composition, lipogenic enzyme activities and mRNA expression of genes related to lipid metabolism in Nile tilapia, Oreochromis niloticus (6.72± 0.14g). An eight week feeding trial was conducted using five isonitrogenous and isolipidic diets containing 0% PO, 25% PO, 50% PO, 75% PO and 100% PO. PO supplementation led to a significant increase in total saturated fatty acid (SFA), total mono unsaturated fatty acids (MUFA) and 18: 2n-6, whiles DHA, EPA, total n-3 as well as 20: 2n-6 were reduced significantly in the liver (P＜0.05). With the exception of glycerol-3-phosphate acyltransferase (GPAT) enzyme activity, supplementing tilapia diet with PO significantly increased fatty acid synthesase (FAS), acetyl-CoA carboxylase (ACC), steroyl-CoA desaturase 1 (SCD1), ATP citrate lyase (ACYL), carnitine palmitoyltransferase Ia (CPTIa) and carnitine palmitoyltransferase Ib (CPT Ib) (P＜0.05). In addition, significant/positive correlations were observed among dietary PO and/or liver tissue FA with FAS, ACC, SCD1 and ACYL mRNA expression while a negative correlation was recorded for CPTI mRNA expression. Generally, inclusion of PO in tilapia diets resulted in lipid accumulation in the liver and altered the key gene expression of lipid metabolism.

“…Mozanzadeh et al . (, ) also reported that silvery‐black porgy juveniles selectively accumulated DHA in the liver. Relative resistance of the DHA‐to‐β‐oxidation and high specificity of fatty acyltransferases for this n‐3 LC‐PUFA make it easier than EPA to selectively retain in some fish tissues (Bell et al .…”

Four isonitrogenous diets containing different carbohydrate:lipid (CHO:L) ratios (0.3, 0.6, 1.1 and 1.8) were tested in triplicate groups (16 fish per replicate) of silvery‐black porgy juveniles for 8 weeks. Growth performance was not affected by different dietary CHO:L ratios (P > 0.05); however, the viscerosomatic index, the intraperitoneal fat, whole‐body lipid, energy and n‐3 long chain polyunsaturated fatty acids levels increased with decreasing dietary CHO:L ratios (P < 0.05). Fish fed with 1.8 CHO:L diet had the lowest apparent digestibility coefficients of protein and lipid, as well as the lowest plasma haemolytic and lysozyme activities (P < 0.05). Red blood cell counts and plasma glucose levels were higher in fish fed with 1.1 and 1.8 CHO:L ratio diets than in the other groups (P < 0.05). Plasma alkaline phosphatase and alanine aminotransferase, as well as the level of lipid peroxidation and total antioxidant capacity in the liver and plasma increased as dietary CHO:L ratios decreased (P < 0.05). The results of the current study indicated that the diets with CHO:L ratios between 0.6 and 1.1 are optimal for silvery‐black porgy, whereas higher ratios may result in hyperglycaemia and immune suppression, and lower CHO:L ratios may lead to oxidative stress and liver dysfunction.

“…The adverse effects of SFAs on nutrient utilization and growth performance might be attributed to the negative effects of SFAs on energy, lipid and fatty acid apparent digestibility, which were linked to higher melting point of SFAs than MUFAs and PUFAs that make them less digestible [89]. From the above results, Mozanzadeh et al [149] stated that VO sources (canola and sunflower oils) were recommended for total and partial replacement of FO in S. hasta diets, which may be explained by the content of crude lipids (4-6%) in FM that would assure the dietary minimum amount of EFAs for proper somatic growth. However, tallow was not advisable as an alternative lipid source in this species, regardless of the levels of lipids included in FM.…”

“…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). In S. hasta juveniles (BW i = 14.6 ± 0.1 g), Mozanzadeh et al conducted an eight-week feeding trial to evaluate the effects of partial (50%) or total (100%) replacement of dietary FO with alternative lipid sources [149]. In this regard, seven isonitrogenous (ca.…”

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.
