| Abstract | Live prey selection by African catfish, Clarias gariepinus, larvae was examined under laboratory conditions. Larvae were offered plankton, plankton + trout starter (TS) and plankton + betaine supplemented trout diet (BTS) for 7 days after exogenous feeding. Five larvae were sampled to determine their gut contents and selectivity index for each treatment 15 min after the feeding. It was observed that dry diets (TS and BTS) improved the growth (P < 0.05), but did not significantly influence the prey selection of the larvae. It was determined that African catfish larvae preferred Copepods and Rotaria sp. to other zooplankton species for all feeding regimes. Ozet: Mevcut cal›flmada karabal›k, Clarias gariepinus, larvalar›n›n canl› yem secimi laboratuar koflullar›nda incelenmifltir. D›fl beslenmeye gecen larvalara 7 gun boyunca plankton, plankton + alabal›k bafllang›c yemi ve plankton + betain ilaveli alabal›k bafllang›c yemi verildi. Yemlemeden 15 dakika sonra her muameleden 5 larva mide iceriklerini ve secicilik indekslerini tespit etmek icin orneklendi. Kuru yemlerin larvalar›n canl› yem secimlerini etkilememesine ramen, buyumelerini onemli derecede iyilefltirdii gozlendi (P < 0,05). Tum yemleme rejimlerinde de karabal›k larvalar›n›n dier zooplankton turlerinden cok Kopepod ve Rotaria turlerini tercih ettii belirlenmifltir. |
