Age structure of annual Nothobranchius fishes in Mozambique: is there a hatching synchrony?

Popis výsledku v původním jazyce

In this study, the age structures of populations of African annual Nothobranchius fishes are examined for the first time. Daily increments in sagittal otoliths of N. furzeri, N. kadleci, N. orthonotus and N. rachovii were used for age determination. Fourhypotheses were tested: 1) timing of hatching is consistent with the calendar onset of the rainy season, 2) hatching is synchronized within a population in a pool, 3) there is a difference in hatching date between geographical regions differing in meantotal annual precipitation, and 4) sympatric Nothobranchius species hatch at the same time. The results show that daily increment analysis represents an applicable method for age determination in Nothobranchius spp. Timing of hatching was not consistentwith the calendar onset of the rainy season. Hatching dates were relatively uniform in some populations, whilst there was considerable variability in others.
