fa بررسی رفتار تغذیه ای لاروماهی شانک زردباله در تغذیه با غذای زنده و خوراک میکروکپسوله تغذيه تغذيه كاربردي Applicable <p style="margin-left:38.75pt;">Feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae&nbsp; on different ratios of live food and&nbsp; microencapsulated diet (MED). Food consumption rate increased progressively with increasing larval weight. The results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to ingest and digest MED from the onset of exogenous feeding.</p> <p style="margin-left:39.2pt;">Comparing the average number of rotifers and MED ingested by larvae in treatments including either only live food or MED did not show any significant differences (P>0.05). In addition, the gut contents examination from the larvae fed simultaneously on both rotifer and MED, revealed that the larvae&#39;s tendency towards live food and/or MED was a function of live food density in the rearing tanks. The larvae preferentially ingest live food even when these are present at a very low concentration in comparison to MED. The mouth diameter of larvae has a strong influence on the amount of ingested rotifers and MED.</p> <p style="margin-left:39.7pt;">There was a significant positive correlation between larvae growth and the &nbsp;average number of both live food and MED ingested by larvae in this trial (P<0.01). Although larvae survival rate had a positive correlation with the number of rotifers&nbsp; ingested, the amount of MEDin the larvae&#39;s gut did not show effect on larvae survival rate (P>0.05).</p> Live Food, Breeding, Rotifer, Yellowfin seabream larvae 51 64 http://isfj.ir/browse.php?a_code=A-10-1417-59&slc_lang=fa&sid=1 B Sarvi بهزاد سروی Sarvi2613@yahoo.com 100319475328460016404 100319475328460016404 Yes A Matinfar عباس متین فر 100319475328460016405 100319475328460016405 No H Mahmoudzadeh همایون محمودزاده 100319475328460016406 100319475328460016406 No G.R Eskandary غلامرضا اسکندری 100319475328460016407 100319475328460016407 No Y Abdollah Tabar یاسر عبداله تبار 100319475328460016408 100319475328460016408 No
