Associated characteristics

Species Development state Trait Primary Data Secondary Data
Osmerus eperlanus Larvae Temperature during larval development The observation of larval develoment was held at the five following regimes at constant temperature: 9.5, 10.8, 12.0, 13.8 and 18.3°C 9.5 °C
Osmerus eperlanus Larvae Full yolk-sac resorption In talking about larval development, we refer to the period from hatching of the embryo from egg shell to full resorption of the vitelline sac. As the age of the smelt is counted in relative duration untis, the larval period falls in the age interval between 200 and 340 ts. The duration of the larval development may be counted easily for each temperature regime using the following formula: log ts (t) = 3.22665 -0.13876t + 0.00297t² where t is the temperature. For example, value ts is equal to 116 min at 10.8°C, so the duration of the total larval development at the given regime is 116 (min) x 140 (ts) = 16240 min or 11 days and 7 hours 11.7 °C * day
Osmerus eperlanus Larvae Initial larval size The l ength of the body is 6.0-6.1 mm including the length from the rostrum the anus, at age 200-210 ts 6.05 mm
