• Lowered nutritional quality of prey decrease the growth and biomolecule content of rainbow trout fry 

  Taipale, Sami J.; Pulkkinen, Katja; Keva, Ossi; Kainz, Martin J.; Nykänen, Hannu (Elsevier Inc., 2022)

  Diet quality is crucial for the development of offspring. Here, we examined how the nutritional quality of prey affects somatic growth and the lipid, carbohydrate, protein, amino acid, and polyunsaturated fatty acid content ...

• Effects of weekend starvation and the duration of daily feeding on production parameters of rainbow trout Oncorhynchus mykiss 

  Tunçelli, Gökhan; Pirhonen, Juhani (Elsevier BV, 2021)

  It would often be practical to starve the cultivated fishes over the weekends, e.g. to save in labour costs. We evaluated the possibility that domesticated juvenile rainbow trout (Oncorhynchus mykiss) could compensate for ...

• The effect of peracetic acid on microbial community, water quality, nitrification and rainbow trout (Oncorhynchus mykiss) performance in recirculating aquaculture systems 

  Suurnäkki, Suvi; Pulkkinen, Jani T.; Lindholm-Lehto, Petra C.; Tiirola, Marja; Aalto, Sanni L. (Elsevier, 2020)

  Microbial biofilters control water quality and enable the overall function of recirculation aquaculture systems (RAS). Changes in environmental conditions can affect the abundance and interactions of the diverse microbial ...

• Effect of peracetic acid on levels of geosmin, 2-methylisoborneol, and their potential producers in a recirculating aquaculture system for rearing rainbow trout (Oncorhynchus mykiss) 

  Lindholm-Lehto, P. C.; Suurnäkki, Suvi; Pulkkinen, Jani; Aalto, Sanni L.; Tiirola, Marja; Vielma, J. (Elsevier BV, 2019)

  In recirculating aquaculture systems (RAS)s, off-flavors and odors, mainly caused by geosmin (GSM) and 2-methylisoborneol (MIB), can accumulate in the flesh of fish from RAS water, reducing the profitability of production. ...

• Tracing activation efficiency of the bio-filtration bacteria in a recirculating aquaculture system using stable isotope analysis 

  Foore, Nathan (2016)

  One challenge in starting a new recirculation aquaculture system (RAS) is to find the most efficient method to activate the nitrifying bacterial biofilm in the bio-filtration system. It has been suggested that chemical ...
