Diet development and evaluation for juvenile abalone, Haliotis asinina Linne: Lipid and essential fatty acid levels

Effects of dietary grape seed oil and linseed oil on growth, muscle fatty acid composition and expression of putative Δ5 fatty acyl desaturase in abalone Haliotis discus hannai Ino

“…And diets containing EFA contributed to the faster growth of abalone (Bautista-Teruel et al, 2011;Durazo-Beltrán et al, 2003;Mai et al, 1996;Xu et al, 2004). Limited growth of abalone in all experimental groups, even though for 120-days period, may be related to the absence of dietary ARA and EPA.…”

“…In contrast, there is little information available on LC-PUFA synthesis across a wide range of aquatic invertebrates including abalone. Previously, some studies suggested that abalone might have the ability to convert LA to arachidonic acid (ARA) or ALA to eicosapentaenoic acid (EPA) based on the results of feeding experiments (Bautista-Teruel et al, 2011;Durazo-Beltrán et al, 2003;Xu et al, 2004). Mateos et al (2011Mateos et al ( , 2012a reported some studies about putitive-Δ6 Fad and elongase (without confirmation of actual enzymatic activities) in Jade Tiger Hybrid abalone (Haliotis.…”

Growth and feed utilisation of juvenile greenlip abalone (Haliotis laevigata) in response to water temperatures and increasing dietary protein levels

“…Fish oil, and the fish oil in fish meal, contains essential long chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs): eicosapentaenoic acid (20:5n-3, EPA), docosapentaenoic acid (22:5n-3, DPA) and docosahexaenoic acid (22:6n-3, DHA) (BautistaTeruel et al, 2011). LC n-3 PUFAs are important for cellular membrane structure and function, controlling and regulating cellular metabolism, and many other aspects of animal physiology (Bautista-Teruel et al, 2011). The LC n-3 PUFA fatty acid profiles of the salmon fish meal and salmon oil used in the current study were not analysed.…”

Amino Acid and Fatty Acid of Abalone Haliotis Squamata Cultured in Different Aquaculture Systems

“…: Kjedahl flask, flask, erlenmeyer, lipid beaker, and Soxhlet tube. While the materials are catalyst (K 2 SO 4 and CuSO 4 ), concentrated H 2 SO 4 , H 2 O 2 ,H 3 BO 3 , indicator solution, Na 2 (SO 4 ) 3 (alkali), HCl, chloroform, aquadest, and abalone Haliotis squamata.…”

“…Cultured abalone also represent a source of LC n-3 PUFA and good source of DPA or consumers [8,20,30,25,26,3]. The LC n-3 PUFA and total lipid contents of marine animals vary depending on various biological and environmental factors, such as diet of the animals, water temperature the reproductive cycle, and the latitude at which they were harvested [8,17,26].…”
