“…diet, which could be due to the high EPA content of the microalga itself. Similar results were also reported in Nile tilapia ( Oreochromis niloticus ) (Sarker et al, ), Jade perch ( Scortum barcoo ) (Van Hoestenberghe et al, ) and Pacific white shrimp ( Litopenaeus vannamei ) (Wang et al, ) when fed the microalga Schizochytrium sp. which was rich in DHA.…”

“…Some microalgae rich in EPA or DHA have already been applied in aquaculture, including Crypthecodinium cohnii (Atalah et al, ; Ganuza et al, ), Phaeodactylum tricornutum (Atalah et al, ) and Schizochytrium sp. (Ganuza et al, ; Sarker et al, ; Van Hoestenberghe et al, ; Wang et al, ). However, the production cost of these organisms remains the major constraint for wide application in aquaculture (Shah et al, ).…”

A 40‐day experiment was conducted to investigate the effects of two filamentous microalgae as feed ingredients on growth performance, tissue fatty acid profiles, pigmentation and immunity of gibel carp (204.83 ± 2.17 g, mean ± SD). Three diets (control, Oedocladium sp. and Tribonema sp.) were formulated. In the control diet, no microalgal meal was added and into the Oedocladium and Tribonema diets were added 40 g/kg Oedocladium sp. meal and 50 g/kg Tribonema sp. meal, respectively. Compared to the control, the addition of Oedocladium sp. and Tribonema sp. had significant effects on tissue fatty acid profiles, antioxidant capacity and immunity without compromising growth, body composition and pigmentation. The addition of Tribonema sp. and Oedocladium sp. significantly increased the EPA, DHA profiles and the ratio of n‐3/n‐6 polyunsaturated fatty acids, and simultaneously decreased the n‐6 polyunsaturated fatty acids profile in fish muscles. Moreover, addition of Tribonema sp. to the diet significantly increased muscle palmitoleic profile and EPA + DHA contents. Furthermore, the addition of either microalga significantly increased the total superoxide dismutase activity level and the complement 3 and immunoglobulin M contents in the plasma. These results demonstrate that Oedocladium sp. and Tribonema sp. can be used as feed ingredients to improve flesh quality and increase the immunity of fish.

“…This species is a freshwater finfish indigenous to Australia, but can be found in many countries including China, America, Malaysia and Singapore (Liu et al, ; Mok et al, ). The fish production appears to be expanding since they are hardy species with a relatively fast growth rate, good tasting flesh and high market demand (Van Hoestenberghe et al, ). Currently, there are no investigations on continuous magnetic exposure on this fish.…”

Influence of continuous magnetic field exposure on water properties and subsequent effects on the growth performance, plasma biochemistry, nutritive value and liver histopathology of Jade PerchScortum barcooin a recirculating system

A 150-days study was conducted on the continuous exposure of magnetized water at 0.00, 0.10, 0.15 and 0.20 Tesla (T) on quadruplicate treatments of Jade Perch Scortum barcoo juveniles in a recirculating system. Each replicate consisted of 18 fish with an average weight of 7.52 g over all treatments. The feeding efficiencies, growth, whole-body proximate plasma parameters, survival were measured and liver histopathology was observed. Our results show no significant improvement in water quality parameters, specific growth rate and body weight gain in this study. However, the best feed conversion ratio was recorded in fish exposed to 0.10, 0.15 and 0.20 T, which are significantly better than the control 0.00 T. Though survival was unaffected but plasma biochemistry and liver histopathology were affected even within the treatment. No liver, plasma or blood abnormalities were detected in fish exposed to 0.10 T and the control 0.00 T. But, one out of four livers from fish in the 0.15 T treatment showed a localized inflammatory response. These changes increased in the liver of fish exposed to 0.20 T, high AST and necrosis in this group is evidence of the liver cells damaged or been at risk. A significantly higher crude protein and lipid were noticed in the exposed fish compared with the control, 0.15 T had the highest crude protein and lipid while the control has the lowest. Based on the overall findings, on growth performance and looking at other factors like absence of any physiological disorder 0.10 T can be used as an effective and affordable technique improve the feeding efficiencies of Jade Perch.

“…Previous studies suggested that the meal of the microalgae Schizochytrium can partially or totally replace fish oil in the diets for aquaculture species, such as such as salmon (Miller et al, ), sea bream (Ganuza et al, ), channel catfish (Li et al, ), jade perch (Hoestenberghe et al, ) and giant grouper (García‐Ortega et al, ). Indeed, current experiment showed that supplying 11% of Schizochytrium meal could substitute fish oil completely without significant different growth.…”

First step of non‐fish meal, non‐fish oil diet development for red seabream, (Pagrus major), with plant protein sources and microalgaeSchizochytriumsp

Fish meal and fish oil are considered as the most nutritious and digestible ingredients for marine fish. The prices of both ingredients are higher than the other protein and lipid sources, such as soybean meal and corn gluten meal, and those have made downward trend of usage amount of fish meal and fish oil in aquaculture. The demand of those two ingredients has shown unbalanced conditions for the decades. According to the FAO, the disparity of supply and demand will continue to increase with the continuous worldwide growth of fish and livestock farming (FAO, 2016). Therefore, to lower the price of fish diet and to reduce the content of fish oil and fish meal in aquafeed, it is necessary to find out alternative sustainable dietary ingredients for aquaculture fish species.Plant protein sources were recommended by many authors and their cost seems cheaper and sustainable than fish meal. However, it is well-known that plant protein sources have issue with anti-nutritional factors and are lack of indispensable amino acid. It seems impossible Abstract A feeding experiment was conducted to develop non-fish meal and non-fish oil diet for red seabream by using plant protein source and Schizochytrium meal which is rich in 22:6n-3 (DHA). Three iso-nitrogenous and iso-lipidic experimental diets were prepared (CP 41.2% ± 0.4%, CL 16.4% ± 1%). Control diet contained both fish meal (40%) and fish oil (6%). In the second diet, fish meal was replaced by plant meals (soy protein concentrate, soybean meal, corn gluten meal) [FO]. In the third diet, fish meal and fish oil were replaced by algae meal (Schizochytrium sp. powder) and plant proteins [AO].Duplicated groups of juvenile red seabream (8.8 g ± 1.5) were fed the experimental diets for 12 weeks to near satiation. There was no statistical difference among treatment in specific growth rate. Feed conversion ratio of AO diet group was higher than that of control. In wet basis, whole body protein level was significantly higher in AO diet than FO group while lipid content was lower than control group. In fatty acid profile, AO group had significantly lower level, but significantly higher 18:3n-3 and DHA level than the other two diet fed fish.The results might suggest that further developments in microalgae diet offer a promising lipid source of n-3 PUFA as essential fatty acid on marine fish. And it showed possibility to develop non-fish meal and non-fish oil feed for marine aquaculture fish by using microalgae. K E Y W O R D Salgae, DHA, feed source, fish feed, oil, red sea bream
