Twenty males and twenty females were observed under semi-natural and experimental conditions to test the hypothesis of serial monogamy. Unde...
متن کاملEffect of rearing temperature on the body shape of Angel fish (Pterophyllum scalare Lichtenstein, 1823) during early development using geometric morphometric method
Temperature as an environmental factor, play important role in fish life. Angel fish (Pterophyllum scalare) is one of the most popular fish species that its production has developed in the ornemental fish industery and there is little information about the effect of rearing temprature in the aquarium.

متن کاملGrowth and reproductive performance by different feed types in fresh water angelfish (Pterophyllum scalare Schultze, 1823)
It is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. In this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. Twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth...

متن کاملSudden weaning of angel fish pterophyllum scalare (Lichtenstein) (Pisces; Cichlidae) larvae from brine shrimp (Artemia sp) nauplii to formulated larval feed
This study investigated the effects of sudden weaning of angel fish larvae (Pteraphylum scalari) from Artemia nauplii to commercial larval feed. Four days post hatch (DPH) larvae were reared in four different weaning protocols (TR1-TR4) with triplicates in a complete randomize design. Larvae in TR1 and TR4 were exclusively fed Artemia nauplii and dry feed respectively. In TR2 and TR3, larvae we...
