Abstract

In this study, it was aimed to determine the larval ontogeny of the balloon Jack Dempsey (Rocio octofasciata Regan, 1903) on the Atlantic slopes from Southern Mexico (Papaloapán River) to Honduras (Ulua River). In addition, embryonic and larval developmental stages were evaluated microscopically. Experiments were performed with 25 brood fish (20 females-5 males) and their reproduction was carried out after the appropriate adaptation period. The ellipsoidal and transparent eggs were found to be short axis with an average of 973.2±21.7 µm and long axis with an average of 2159±84.5 µm (n:60). Eggs have started to hatch at 27.30±0.41°C approximately 52 hours after spawning. It was determined that the total length of the newly hatched larvae was around 3220±20 µm (n:30), they started to feed exogenously 6 days after hatching and they started to take particulate and powder feeds at the end of 21 days after hatching. The early-stage growth formula calculated with Jack Dempsey's exponential relationship model is y = 4.097e0.052x (R2 = 0.8669, n=30).

Özet

Bu çalışmada, Atlantik’te Güney Meksika'dan (Papaloapán Nehri) Honduras'a (Ulua Nehri) kadar yayılış gösteren balon Jack Dempsey (Rocio octofasciata Regan, 1903) balığının larval ontogenisinin belirlenmesi amaçlanmıştır. Bununla beraber, embriyonik ve larval gelişim aşamaları mikroskobik olarak değerlendirilmiştir. Denemeler 25 adet anaç balık kullanılarak (20 dişi-5 erkek) gerçekleştirilmiş ve uygun adaptasyon süresinden sonra üremeleri gerçekleştirilmiştir. Elips şeklinde ve şeffaf yapıda olan yumurtaların çapları kısa eksende ortalama 973.2±21.7 µm, uzun eksende ortalama 2159±84.5 µm (n:60) olarak bulunmuştur. Yumurtlamadan yaklaşık 52 saat sonra 27.30±0.41°C'de yumurtalar açılmaya başlamıştır. Yumurtadan yeni çıkan larvaların total boylarının 3220±20 µm (n:30) civarında olduğu, kuluçkadan 6 gün sonra eksojen beslenmeye başladıkları, 21 gün sonra partikül ve toz yemler almaya başladıkları belirlenmiştir. Jack Dempsey'nin üstel ilişki modeliyle hesaplanan erken evre büyüme formülü y = 4.097e 0.052x'tir (R2 = 0.8669, n=30).
