Record #139221:

Oogenesis and gonad maturation in the copepod Calanus finmarchicus and the prediction of egg production from preserved samples / Barbara Niehoff, Hans-Jürgen Hirche.

Title: Oogenesis and gonad maturation in the copepod Calanus finmarchicus and the prediction of egg production from preserved samples / Barbara Niehoff, Hans-Jürgen Hirche.
Author(s): Niehoff, Barbara.
Hirche, Hans-Jürgen.
Date: 1996.
In: Polar Biology. (1996.), Vol. 16(8) (1996)
Abstract: Study was made in transition from winter to spring in fjord in northern Norway. Observations on whole (transparent) animals and histological sections were combined to establish system of maturation stages, to describe spawning cycle and to estimate egg production rates from preserved samples. Four oocyte stages were identified and related to macroscopic system of four gonad development stages that can be applied to whole stained animals.To predict egg production rate one must know clutch size and interval of clutch deposition, which should be possible solely from preserved samples.
