FISH CULTURE

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. 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.

Weighing Fecundity. Absolute Fecundity [is] often attributed to weight, because weight more is coming near [is] condition of that fish than length. But in [relation/link] of fecundity weighing there are some difficulty. Heavy will quickly change when prolific season. For example fish of salmon and of sidat [doing/conducting] journey before is prolific, they [shall] no longger take food, become to fast to place of breed. Material for its growth [of] him taken away from [by] network of somatik. Therefore if participating correlation of fekunditas weighing of somatik in comparing one population with population or among two season have to take a care. If absolute fecundity mathematically total weighing correlation [is] including weight of gonad will generate difficulty statistically. Cause will be [entered/included] [by] egg in number larger ones of fish which in fact small berfecundity. Also [is] same difficulty will arise if fecundity attributed to factor of[is condition of, because in f

population fecundity relative from one hundred, a thousand or ten thousand individual of certain age group. Amount of fish in every age class multiplied [by] mean fecundity of that age. Result of which [is] got from suming all age group give fecundity relative. this fecundity can differ from year to year because many individual which is not prolific annually. If in one year, there are individual in number many will cause low fecundity in the year the other. fecundity with length . fecundity [is] often attributed to length than weighing, because its decrease length [of] infinitesimal relatip [do] not like weight able to decrease easily. Matter which must be paid attention in making [relation/link] of fecundity with length if taking sampel which repeatedly have to take a care, because if taken fish when gonad [is] growing this matter [do] not represent growth of somatik. Become here difference there must be [among/between] growth of somatik with growth of gonad. Most [all] writer plot ab
