Under current experimental conditions, Atlantic salmon were used as donors of intestinal microbiota, whereas gilthead seabream were chosen as recipients. In particular, Atlantic salmon with an initial body weight (BWi) of 55.0 ± 0.1 g (mean ± SD) were …

Fish tracking for automatic detection of reproductive behaviour
Automatic fish detection and tracking for analysis of reproductive behaviours in Senegalese sole (Solea senegalensis) using neural networks and DeepSORT algorithm.
The objective of this study was to automate the detection of reproductive behaviours based on captured videos and a machine leraning system, maintained in optimal conditions with a reccirculation system IRTAmar®. The senegale sole behaviours …
A comparison of recirculation aquaculture systems versus biofloc technology culture system for on-growing of fry of Tinca tinca (Cyprinidae) and fry of grey Mugil cephalus (Mugilidae)
The IRTAmar® RAS systems, recirculation modules capable of recycling up to 0.5 kg of food with a protein level of 50 % and volumes of 4,500 L per hour, were used for the trial. Each …
Trout challenge experimental design
Unvaccinated rainbow trout juveniles were purchased from Truchas de Leiza SL (Leiza, Navarra, Spain), and transported to IRTA research facilities in la Ràpita (Tarragona, Spain). Trouts were acclimated during two weeks in a 6 m3 tank …
Rainbow trout pathogenic bacterial challenge
To investigate whether the replacement of FM by increased levels of BSCP compromised the immune response of rainbow trout juveniles fed experimental diets, an in vivo bacterial challenge with the strain IRTA-17-44 of A. salmonicida …
Dominance behaviour in a non-aggressive flatfish
Senegalese sole juveniles (~ 45 g) were provided by Stolt Sea Farm (Santiago de Compostela, Spain), different fish from the same batch were used for two successive years to conduct different behavioural tests. Fish were …
Atlanctic salmon bacterial challenge
In order to investigate the immunomodulatory properties of the phytogenic compounds against bacterial infection, an experimental bacterial challenge with the strain IRTA-17-44 of A. salmonicida subsp. salmonicida was performed at the end of the nutritional trial. Bacterial suspensions of the …
Real time data on RAS
Having data in real time is a powerful tool for analyzing the behavior of the system and the animals. Knowing the period before and after a certain event does not help to know the causes …
Spicing up aquafeeds
A good experimental design is the key to ensuring that the trials provide sufficient information to be able to analyze the results from a broad perspective. IRTAmar® provides the necessary versatility so that the design …
