Description of hake (Merlucius merlucius) spermatozoa: flagellar wave characteristics and motility parameters in various situations

Popis výsledku v původním jazyce

The objective of this study was to complement published hake (Merlucius merlucius) sperm motility characteristics by obtention of data more specifically dependent on flagella: beat frequency, flagellar wave amplitude, wave length, number of waves along the length of the flagellum and curvature of the wave. The changes of these parameters are described in relation to the time period elapsed since activation are described using high resolution video images of flagella while quantifying the progression during the swimming period from the activity initiation to full cessation of movement several minutes later. The main characteristic of the swimming period of hake spermatozoa shows a progressive decrease of forward displacement resulting from a cumulativedecrease of several activity descriptors: the beat frequency, the percentage of motile cells, the wave amplitude, the number of flagellar waves and the linearity and shape of flagella. All these parameters decrease within 7-8 min after ac
