Abstract: Morphological development and allometric growth of laboratory reared Nannacara anomala were studied from hatching to the loss of larval characters and beginning of squamation (18 days post-hatching) at 26°C. The mean total length (TL) of larvae and juveniles increased from 3.74 mm at hatching to 9.60 mm at metamorphosis. Morphogenesis and differentiation were most intense during the first week of development. During this period (TL interval = 3.74 -4.84 mm) there was an evident priority to enhance the feeding … Show more

“…The fast initial growth in the head region (allometric growth of HL, HD, ED) is probably linked to the development of nervous (midbrain and hindbrain), sensory (vision and olfaction), respiratory (gill arches and filaments), and feeding systems. Increasing head size is associated with a more developed nervous system, allowing better oxygen uptake and the application of food particles of increasing size (Fuiman 1983;van Snik et al 1997, Koumoundouros et al 1999Gisbert et al 2002;Kupren et al 2014b). In the posterior part of the body, rapid tail growth of dace individuals (allometric growth of TAL, BDA, and TD) was concomitant with the development of musculature, unpaired fins, caudal peduncle, and fin rays.…”

“…At hatching, the larval functional systems were mostly undifferentiated, a condition previously pointed out (Guimarães-Cruz et al, 2009). Major morphogenesis in early life is a prevailing condition among teleosts van Snik et al, 1997;Nakatani et al, 2001;Guimarães-Cruz et al, 2009, 2014Kupren et al, 2014). The challenges that fish face in early life are especially arduous because their relatively small size constrains the ability to avoid predators, capture prey, and withstand starvation (Barriga & Battini, 2009).…”

“…The number of pairs used in studies of allometric growth of early life stages of domestic fish are often small, less than 6 (e.g. van Gisbert, 1999;Gisbert & Doroshov, 2006;Kupren et al, 2014).…”
