Conservation biology?

You tag 250 juveniles and 120 adults in the wild. You also observe that adult females tend nests where they deposit eggs. You collect some of the eggs to hatch and rear in aquaria back in the lab. Next year, you recapture as many tagged fish as you can and find that 64 or the juveniles have become adults and 31 are still juveniles. The rest are nowhere to be found and you presume they have died. You recapture 97 of your tagged adults. Use these data as appropriate to determine values for the rates axy from the previous question (please express these numbers as fractions, rather than decimal numbers). What data from the field and the lab would you need to determine a value for the remaining rate?

now, the next questions asks this:

Now use the data described in the previous question to determine values for per-capita survival (S), growth (G), and fecundity rates (F), again in terms of fractions rather than decimals. Add an appropriate subscript for any rate that occurs in more than one stage (in this case, to distinguish between adult and juvenile survival). Express each rate axy the previous question in terms of the biologically appropriate combination of the three underlying vital rates (S, G, and/or F).

i dont have enough information to calculate the fecundity rates do i?

You don't have enough data to calculatefecundity .

data?.,.
