dc.description <p>Bu &ccedil;alışmada, Japon balıklarının (Carassius auratus) erken larva d&ouml;nemi besleme programının geliştirilmesi i&ccedil;in canlı ağırlıkları 0,97-1,13 mg ve total boyu 5,77-6,05 mm olan 2340 adet besin kesesi &ccedil;ekilmiş larva kullanılmıştır. Larvalar farklı yemleme zamanı (T1-4 ) ve farklı yemlerle (Y1-3 ; biri ticari karma yem, diğer ikisi deneme yemi) on beş g&uuml;n s&uuml;resince beslenmiştir. Kontrol gurubu (KY) da dahil olmak &uuml;zere 13 farklı muamele 3 tekerr&uuml;rl&uuml; olarak denenmiştir. Denemede 8. ve 15. g&uuml;nlerde periyodik &ouml;l&ccedil;&uuml;mler yapılmıştır. Veriler fakt&ouml;riyel (T1-4 X Y1-3 ) d&uuml;zende analiz edilerek grup ortalamaları Tukey y&ouml;ntemiyle, kontrol ve alt gruplar ise Dunnett testiyle karşılaştırılmıştır. Elde edilen yaşama ve b&uuml;y&uuml;me oranları, farklı yemleme zamanı ile canlı ve kuru yem kombinasyonlarından &ouml;nemli derecede etkilenmiştir. Kısaca, s&uuml;rekli olarak kuru yemlerle besleme, rotifer ve kuru yem kombinasyonları kadar başarılı olmamıştır. Beslenmeye rotiferle başlanan gruplarda canlı yemle besleme s&uuml;resi arttık&ccedil;a, b&uuml;y&uuml;me ve yaşama oranları da artmıştır. Buna g&ouml;re 15 g&uuml;nl&uuml;k toplam besleme s&uuml;recinde ilk 7 g&uuml;n canlı yem (rotifer) sonra 3 g&uuml;n s&uuml;reyle canlı yem+kuru yem ve daha sonra 5 g&uuml;n s&uuml;reyle de tamamen kuru yemle beslenen grupların (T4Y1-2-3 ) daha başarılı olduğu g&ouml;r&uuml;lm&uuml;şt&uuml;r. B&ouml;yle bir program Japon balığı erken larva d&ouml;nemi besleme programı olarak &ouml;nerilebilir.&nbsp;</p>
dc.description <p>The aim of this study was to develop a feeding program for early larval stage of goldfish (Carassius auratus) with an initial weight of 0.97-1.13 mg and total length of 5.77 - 6.05 mm. The study was conducted with totally 2340 larvae during 15 days, and included 13 groups with three replications. Four different feeding times (T1-4 ), three different dry (D1-3 &ldquo;one commercial feed and two test&rdquo;) diets plus continuous live food were the treatments. Larval growth were checked on 8th day and at the end of the experiment. Dry diets were fed to larvae continuously (T1 ) or after 3 (T2 ), 5 (T3 ) and 7 (T4 ) days of rotifer feeding. Also, in the control group only rotifer (R) was fed for 15 days. Results were analyzed with the factorial analysis design (feeding times &times; diets) and compared using the Tukey multiple comparison test. A comparison of the control group R with subgroups were also made using the Dunnett?s test. The present results indicate that various combinations of &ldquo;live and dry foods&rdquo; administered at different durations significantly effected growth and survival rates of goldfish larvae (P&lt;0.05). Briefly, continuous feeding with all dry diets were not as successful as the others. As the duration of rotifer feeding as first food increased, larval growth and survival also increased even if still worse than the control (15 days rotifer). The best practice for early larval feeding of goldfish could be T4D1-2-3 (7 days rotifer, 3 days rotifer + dry diet and 5 days dry diet) during the first 15 after hatching</p>
