Sự vận chuyển cá bột loài cá bơn (Platichthys flesus L.) ở vịnh MariagerAbstract
Flounder larvae (Platichthys flesus L.) were studied from April to June 2000 in Mariager Fjord, Denmark. Low density (1.0 individual per 100 m3) of larvae was found in the fjord during the sampling period and most larvae were found in April. Flounder larvae were observed to utilise the tidal currents for their upstream transport. Higher densities of flounder larvae were found in the surface layer during flood than ebb tide, whereas the opposite pattern was found near the bottom of the water column. The hypothesis that flounder larvae are hatched in the fjord was rejected because no flounder larvae at the early stage II and I was found in the samples. The transport time needed by larvae for upstream migration over a distance of 9 km was about 3.5 – 4 days. Hatch date analysis showed that flounder larvae in Mariager Fjord were hatched in two different periods and they might represent two different cohorts of larvae.Journal
