DHA (22:6n-3) supplementation is valuable in Totoaba macdonaldi fish oil-free feeds containing poultry by-product meal and beef tallow

Trophic Levels Predict the Nutritional Essentiality of Polyunsaturated Fatty Acids in Fish—Introduction to a Special Section and a Brief Synthesis

“…Additionally, diet-to-tissue transfer of 22:6n-3 is enhanced among Cobia fed SFA-based feeds (Woitel et al 2014a(Woitel et al , 2014b. Based on these data and other recent findings from our group (Trushenski and Kanczuzewski 2013;Trushenski et al 2013aTrushenski et al , 2015Rombenso et al 2015Rombenso et al , 2016aRombenso et al , 2016bRombenso et al , 2017Rombenso et al , 2018Bowzer et al 2016;Emery et al 2016;Bergman and Trushenski 2018;Mata-Sotres et al 2018) it seems likely that LC-PUFA nutritional requirements could be met at lower dietary inclusion rates if the required fatty acids are provided in the context of SFA-rich alternative lipids.…”

“…Totoaba Totoaba macdonaldi (a warmwater marine carnivore) the importance of 22:6n-3 was confirmed, as was the apparent essentiality of 20:4n-6, though there appeared to be some additional benefit in providing 20:4n-6, 20:5n-3, 22:6n-3 together in some cases (Bowzer et al 2016;Emery et al 2016;Rombenso et al 2015Rombenso et al , 2016aMata-Sotres et al 2018).

Growth, thermal preference and critical thermal maximum for Totoaba macdonaldi: effect of acclimation temperature and inclusion of soybean meal in the diet

“…Corresponding editor: Alvaro Bicudo Totoaba (T. macdonaldi) is a species endemic to the Gulf of California (Flanagan & Hendrickson 1976) that is considered to have aquaculture potential (Rueda-López et al 2011). Recent studies have evaluated its nutritional requirements (Badillo-Zapata et al 2016, Fuentes-Quesada et al 2018, Mata-Sotres et al 2018. However, no studies have addressed the effect of the thermal conditions, particularly the interaction between temperature and diet, on its biological performance.…”

Prebiotic agavin in juvenile totoaba, Totoaba macdonaldi diets, to relieve soybean meal‐induced enteritis: Growth performance, gut histology and microbiota

“…However, its high crude fat content (close to 15%; CF) makes it challenging to formulate diets as the primary protein source, especially in those species with low crude fat requirements as totoaba (Rueda‐López, Lazo, Correa‐Reyes, & Viana, 2011). Additionally, PBM lacks LC‐PUFAs making the FM replacement struggling (Badillo‐Zapata et al, 2016), unless a DHA extract is supplemented (Mata‐Sotres et al., 2018).…”
