NANFA-- Something about fish death after spawning season
Thu, 21 Jun 2001 23:11:54 +0700

Though the situation is somewhat different, here in Thailand streams I had
collected nemacheiline loaches in late winter [here in March] and most are
healthy, fat and many females are filled with eggs that sometimes run out of the
body even without pressing the belly. In late April [just past the peak of the
hottest time of the year] most I collect are thin and females become very rare.
Since these nemacheiline loaches produce large [>1mm] clear orange eggs is it
possible that the energy and resources used to produce these eggs exhaust the
female and the lack of nutritious food and rising temperature do them in?
