. Growth in salmon smolt

    urgent. Growth in salmon smolt

    1. The problem statement, all variables and given/known data

    smolt weith is 35g we shall find the weight after 61 days.

    2. Relevant equations

    specific growth rate:; K' = Ln (N2 / N1) / (t2 - t1)
    growth rate is 1,9 %


    3. The attempt at a solution

    I find 110g when I use this forumula 35g*1,019^61
    But Others have found 115g as answer. So im confused. My formula might not be valid for this ?

    also if I use this calculator and put in 1 day 35g and 61 day 110 g The growth rate is only 1.87 and with 115g its 1,95 but with 112g its 1.9 So if this calculator is correct 112g the right answer ?

    Please answer if you understand. Its probably a easy task im just so confused
