Buna göre alıştırma sıcaklıkları balıkların alt ve üst sıcaklık toleranslarını 3-4 °C etkilemiştir. CTMin alıştırma tepki oranı (ARR) değerleri alıştırma sıcaklıklarına bağlı olarak kılıçkuyrukta 0,42-0,42, platide 0,20-0,34 arasında değişirken, CTMax ARR değerleri kılıçkuyrukta 0,29-0,48, platide ise 0,33-0,44 arasında değişmiştir. Platinin termal tolerans poligon alanı (232 °C2) kılıçkuyruktan (217,3 °C2) biraz daha geniş bulunmuştur. İki balık türünün alt sıcaklık toleranslarının düşük olması, kışın su sıcaklığının 10 °C’ye düştüğü subtropikal iklimlerde bu balıkların coğrafik dağılımlarını ve yetiştiriciliklerini sınırlar. KW - Sıcaklık toleransı KW - Poeciliidae KW - TTPA KW - CTM KW - ARR N2 - Thermal tolerance parameters of swordtail (Xiphophorus maculatus) and platy (X. helleri) at three acclimation temperatures were determined in the study. The CTMin values at 20, 24 28°C acclimation temperature were 9.41,10.42 and 11.95 °C respectively for platy and 9.38,11.5 and 13.23 °C for swordtail, while CTMax values were 37.41, 39.19 and 40.52 °C for platy and 36.94, 38.89 and 40.07 °C for swordtail. Accordingly, acclimation temperature affected the lower and upper temperature tolerances of fish by 3-4 °C. The CTMin ARR values varied between 0.42-0.42 in swordtail and 0.20-0.34 in platy, while CTMax ARR ranged between 0.29-0.48 in swordtail and 0.33-0.44 in platy depending on acclimation temperature. Thermal tolerance polygon area of platy (232 °C2) was slightly higher than that of swordtail (217.3 °C). The fact that both fish species have lower temperature tolerances is limits their geographic distribution and aquaculture in subtropical climates where the water temperature drops to 10 °C in winter.
