“…In the same trend, Shehata and Goda (2000) found that dietary lipid levels and sources affect the immune response of Nile tilapia broodstock in winter season. Attalla (2009) concluded too that oil extracts can promote growth performance and improve the physiological activities of blue tilapia (Oreochromis aureus).…”

This study was conducted during the summer season (June-October) 2018 in fish farm at Al-Manzala city for 150 days. A total number of 750 mono-sex Nile tilapia with an average initial body weight of 52.6 ± 0.40 g were used in five experimental treatments (150 fish/hapa/treatment, 10 fish/m 3) to evaluate two dietary crude protein levels (25 and 30%) and two crude fat levels (2 and 6%) from three fat sources (corn oil, imported fish oil, and a new local commercial source of fatty acids named Aquafat-omiga). Fish were stocked into net hapas, each hapa has the dimensions 3 x 5 x 1 m. Conclusively, from the obtained results and due to the view point of the producers, 2 % fish oil supplemented diet (25 % protein) is the most economic diet (lowest feed intake, best feed conversion and feed efficiency) followed by that (25 % protein) supplemented with 2 % Aquafat-omiga. But from the view point of the consumers, 30 % crude protein diet plus 6 % addition corn oil gave best body gain and fish carcass protein, boneless meat and lean meat besides lowest fat and ash in fish body and lowest serum cholesterol, uric acid, and cortisol. So, it could recommend using the first diet containing 30 % crude protein and supplemented with extra 6 % corn oil. Particularly, fish oil is rear, unavailable, imported, and expensive.

“…The obtained negative effects of AFB on fish skin, gut, liver, and kidney are reflecting the low immunity, since these organs belonging to the fish immune system (Press and Evesen, 1999) and blood proteins are non-specific immune factors (Shehata andGoda, 2000 andHussein andKobeisy, 2001). Moreover, Abdelhamid et al (2004a, b, & c) evaluated the toxicity symptoms in Oreochromis niloticus, whether on growth performance, feed and nutrients utilization, clinical, blood, and histological signs.…”

The aim of this experiment was to investigate the effect of aflatoxin B (AFB) in the diets of Nile tilapia (Oreochromis niloticus) and to examine the detoxification activity of a commercial anti-mycotoxin ARCAVIT ® Bioacid Forte. The experimental period lasted 70 days during September-December 2018. Sixty fish were chosen with an average initial weight of about 40 g then randomly distributed into three treatments in six glass aquaria (30 × 60 × 40 cm); each treatment was applied in two aquaria (replicates). Dietary AFB was added at a concentration of 5 ng / g diet. The anti-mycotoxin ARCAVIT ® (pro-and prebiotics) is one of the commercial anti-mycotoxins in the local market. It is the first test for it in aquaculture, which was added at a concentration of 0.5 g/Kg diet. The experimental diets of the three treatments were; the control treatment (T 1): the basal diet (BD) without any additives. The second treatment (T 2): BD with an addition of 5 ng AFB / g diet. The third treatment (T 3): BD with an addition of 5 ng AFB / g diet and 0.5g ARCAVIT ® / Kg diet. Fish fed the experimental diets at a daily rate of 3% of their live body weight, at two meals. The obtained results showed that AFB is very toxic, even at a low concentration as 5 ng / g diet, for Nile tilapia. It threats fish morphology, gross pathology, liver histology, growth performance, and internal organs indices, feed utilization, body composition, and properties, as well as hematological and plasma biochemistry parameters. Moreover, the anti-toxic agent (ARCAVIT ®) at the tested level did not completely overcome the aflatoxicity symptoms. That leads to keep the old wisdom "Prophylaxis is better than cure". 1985 and Kumar et al., 2018) and to control mycotoxicoses (Abdelhamid and Mahmoud, 1996; Abdelhamid et al., 2002a, b &c; 2004 a, b &c and 2007). All these attempts concluded that exact overcome of mycotoxicoses is impossible, so recommended the prevention (Prophylaxes that is better than cure). Hence, the aim of the present research was to study the effects of a new commercial feed additive aiming in ameliorating fish aflatoxicosis. MATERIALS AND METHODS Experimental fish: Unsexed Nile tilapia fingerlings collected from Lake Manzala in September 2018 and transferred to Elmataria Station for Aquatic Research, Dakahlia Governorate, National Institute of Oceanography and Fisheries, Egypt in order to investigate the effect of aflatoxin B (AFB) in the diets of Nile tilapia (Oreochromis niloticus) and to examine the detoxification activity of a commercial anti-mycotoxin ARCAVIT ® Bioacid Forte (Italy Product) distributed in Egypt by ALLgaeuvet Egypt. The experimental period lasted 70 days (10 weeks). The experiment started on 15 th of September 2018 and finished on the 2 nd of December 2018. After 2 weeks adaptation period in a 3m 3 fiberglass tank; during that period, fish were fed a basal diet (BD) from Bio Feed Factory (Asafra Industrial zone, Dakahlia governorate, Egypt). Fish (40 g initial body weight) were randomly distributed into three treatments i...
