Fecundity with race

Fecundity with race.

different Stok Fecundity of [is] same species have been weared for the distinguishment of race by many researcher. Different race have the nature of large size unegual fecundity and so do its egg. Hence species coming from one arrest area can know from amount of its egg. Pursuant to this matter, population can know heterogeneous or homogeneous. Fishs from one species live in various habitat like different river or in territorial water which, differing latitude possible have difference of egg in its its.

Fecundity of the size egg

Fecundity of the size egg.

Egg size measure [is] usually weared to determine the quality of related to egg yolk content where king sized egg yield king sized larva than small fairish. In making comparison of egg size measure with fekunditas have to come from [is] same ovari [of] its maturity storey;level. [Is] often anticipated that fecundity of the size egg have negative correlation [to]. [At] prolific fish duplicate to be got that egg [released] [at] small fairish breeder later;then. Although [do] not there are at all of fish [is] but got that egg size measure and fish footage have positive correlation [to], where this matter [is] followed [by] prolific king sized fish o!eh beforehand.

doubled Breeder Fecundity

doubled Breeder Fecundity.

prolific fish repeatedly during llama will entangle problem of reserve egg and egg which have expanded. Its criterion that is there [is] [do] not it[him] egg yolk. Amount of egg having its [counted/calculated] egg yolk it[him] for that season. This criterion according to Bagenal ( 1978) have been used by some writer. De Sylva ( in Bagenal, 1978) have succeeded to anticipate the amount of generation ( egg amount and batch) every generation.
If fish have egg which consist of some group, hence egg group which have expanded will be [released] at one time. By comparing the amount of egg which have had egg yolk with amount of egg which [is] very expand, to be assumed can give the amount of egg [at] [released] group every season.

total fecundity [of] fish. fecundity in fish ovari

total fecundity [of] fish.
fecundity in fish ovari.

In ovari usually there [is] two kinds of egg size measure, small and big. That big egg will be [released] in the year and small will be [released] next in the year. But often happened if condition of goodness, small egg even also will be [released] to catch up big egg. Referring to this matter hence suggested to determine fish fecundity if that fish ovari [is] in maturity phase which to IV ( according to Nikolsky) and momentary best before happened breeder.
individual fecundity will difficult to apply for fishs performing [a] breeding several times in one year, because containing egg from various storey;level and will be more be difficult again determine really egg will be [released] in the year to come. Become this good individual fecundity applied [at] fishs performing [a] annual breeding or one year once. Referring to this matter hence irrelevant individual fecundity with total fecundity. Royce ( 1972) expressing that total fecundity [is] the amount of yielded [by] egg [is] fish during life.
