Some yeast strains have been proposed as probiotics to improve the health of cultured fish. Cobia is a tropical benthopelagic fish species with potential for marine aquaculture; however, one main limitations its large-scale production high mortality larvae. In this study, we evaluated probiotic autochthonous yeasts from intestines cobia. Thirty-nine isolates were recovered intestinal mucosa 37 adult healthy cobia by culture methods. Yeasts identified sequencing ITS and D1/D2 regions 28S rRNA...
This study investigated the effect of intermittent feeding on water quality, occurrence skin parasites, feed consumption, and growth performance juveniles (102.7 ± 5.1 g) longfin yellowtail, Seriola rivoliana. Fish were exposed for 89 days to six different regimes: continuous daily fed one or twice a day (treatment 24R1 24R2); 2-day fasting refed once 1 48R1 48R2); 3-day 96R1 96R2). Water quality was not affected by strategies. Likewise, condition factor up 48 hr. On other hand, lowest...
The bacterial community of the intestinal microbiota influences many host functions, and similar effects have been recently reported for fungal (mycobiota). Cobia is a tropical fish that has studied its potential in marine aquaculture. However, study underreported mycobiota not investigated. We analyzed gut profile present mucosa reared adult cobias fed two diets (frozen pieces (FFPs) formulated feed (FF)) 4 months by sequencing 16S rRNA (V3-V4) internal transcribed spacer-2 (ITS2) regions...
Abstract The median lethal concentration (LC 50 ) of unionized ammonia (NH 3 ‐N) in longfin yellowtail, Seriola rivoliana juveniles was assessed after 96 h exposure using a semistatic water system. Experimental fish were exposed triplicate to different concentrations: 0.55 ± 0.00; 0.94 0.02; 1.18 1.72 0.02, and 1.97 0.09 NH ‐N mg/L. Additionally, control group (0.00 0.00 mg/L) included. LC S. 0.58 Fish concentrations for displayed several lesions on gill tissues, that is, hyperplasia,...

Aquaculture is a productive activity in economic growth due to market productivity which supports many Ecuadorian communities. However, exotic species has been the basis of this without considering endemic and mega-diverse component Ecuador. On other hand, current aquaculture systems use lot water, generating discharge nitrogen phosphorus, causing negative impact on natural watersheds. The present investigation focused diversification production environmental care, through polyculture...
