Summary The effects of a commercial probiotic diet supplement (Bactocell ® ), containing lactic acid bacteria Pediococcus acidilactici were evaluated by identifying five zebrafish ( Danio rerio ) sperm quality markers. P. acidilactici (10 6 colony‐forming units per gram) was supplied to young zebrafish males (age 8 months) as a feed probiotic additive during a 10 days test period. Five transcripts, previously described as male zebrafish quality markers, were studied: brain‐derived neurotrophic factor ( bdnf ), BCL 2‐interacting killer ( bik ), double‐sex and mab‐3 related transcription factor 1 ( dmrt1 ), follicle‐stimulating hormone beta subunit ( fshb ) and leptin a ( lepa ). After exposition, males fed on with the supplemented diet with a commercial probiotic containing P. acidilactici presented an over‐expression on three fertility markers comparing to the control group: lepa , dmrt1 and bdnf . These results suggest that P. acidilactici has a potential use as probiotic supplement in zebrafish diet for the improvement of molecular parameters in testicular cells, indicating that probiotic supplementation could affect male reproductive performance.
