“…This outcome suggests that the duration between gamete release and the appearance of recruits >2 cm is about 2 months. This result sounds plausible, given the fact that larval dispersion in most pomacentrids is reduced (10-24 days, Thorrold andMilicich 1990, Nemeth 2005), and that males guard fertilized eggs for only a few weeks (Thresher 1984, Asoh and Yoshikawa 2002, Bessa and Sabino 2012. Some authors have suggested that some variability in the time of recruitment may arise as a result of several spawning acts, or that larval duration varies due to environmental uncertainty (Robertson 1990, Thorrold andMilicich 1990).…”

Summary:Similiparma lurida is a common fish inhabiting shallow-water rocky bottoms of the northeastern Atlantic oceanic archipelagos, and the coasts from Portugal to Senegal. This study was conceptualized to integrate information relative to key population traits of S. lurida, including length and age structure, growth, reproduction and length at maturity, with a description of abundance patterns on shallow reefs, including temporality of recruitment and habitat preferences by juveniles, sub-adults and adults. We then hypothesized that seasonal cycles of spawning and recruitment were synchronized. This species reaches a total length (TL) of up to 15.7 cm and an age of 18 years. Males grow faster and longer (K=0.28 years -1 , L ∞ =14.487 cm TL) than females (K=0.23 years -1 , L ∞ =13.461 cm TL), which affects the overall ratio of males to females (1:0.26). The size at which 50% of sexual maturity is reached was 10.344 cm TL for males and 8.471 cm TL for females. Fish increase growth during the spawning season, which occurs from November to March, including a maximum in February. After two months of this peak, juveniles reached maximum abundances (April) in high relief reef areas. Adults, however, show a preference towards rocky bottoms covered with algae interspersed with sand patches, suggesting ontogenetic changes in microhabitat preferences when juveniles turn into adults.Keywords: Pomacentridae; Similiparma lurida; life history; recruitment; coastal fish; spatial distribution; northeastern Atlantic.Estrategias de vida de un relevante pez de arrecife, la fula negra Similiparma lurida (Pomacentridae) en el Noroeste Atlántico Resumen: Similiparma lurida es un pez común que habita en aguas poco profundas de fondos rocosos someros de los archipiélagos oceánicos del Atlántico Norte, y las costas desde Portugal a Senegal. Este estudio se conceptualizó para integrar información relativa a atributos poblacionales clave de S. lurida, incluyendo: estructura de tallas y edad, crecimiento, reproducción y talla de primera madurez con la descripción de los patrones de abundancia en arrecifes poco profundos, incluyendo la temporalidad en el reclutamiento y preferencias de hábitat por juveniles, sub-adultos y adultos. Esta especie alcanza hasta 15.7 cm de longitud total (LT) y 18 años de edad. Los machos crecen más rápido y son más largos (K=0.28 years -1 , L ∞ =14.487 cm LT) que las hembras (K=0.23 years -1 , L ∞ =13.461 cm LT), lo que afecta a la sex ratio de machos y hembras (1:0.26). El tamaño en el que se alcanza el 50% de la madurez sexual fue 10.344 cm (LT) para los machos y 8.471 cm (LT) para las hembras. El crecimiento es mayor durante la temporada de desove, que ocurre de noviembre a marzo, incluyendo un máximo reproductivo en febrero. Dos meses después de este pico (abril), los juveniles alcanzaron abundancias máximas en zonas de arrecifes de gran relieve. Los adultos, sin embargo, muestran una preferencia hacia los fondos rocosos cubiertos de algas intercaladas con parches de arena, lo que sugiere cambios ontogené...

“…44 According to previous studies, water temperature, dissolved oxygen, pH, light and hereditary variation can influence the speed of fish embryo development. 45,46 Hatching timing may also depend on the size of the eggs, because the yolk material is frequently correlated with the duration of prehatching development. 47 Influence of external environmental conditions on the embryonic development still needs to act through gene expression and regulation.…”

The information on the early ontogeny of the endemic Labeobarbus megastoma and Labeobarbus platydorsus fish species of Lake Tana are absent. In this paper we describe for the first time the full developmental sequence from egg to fingerling in controlled conditions. In addition, information on larval behavior, identification and developmental rates are provided. Embryonic development lasted 50:30h (26.3°C) and 61:38 (23.4°C) for the two species L. megastoma and L, platydorsus respectively and larval development to the morphology until the fry became very similar to the adult fish lasted 40 days (24.4°C). The mean total length of the newly hatched larvae of L. megastoma and L. platydorsus were 5.7±0.03 and 6.4±0.03mm respectively. The larvae hatched with closed mouth and anus, unpigmented eyes, large yolk and complete yolk absorption and exogenous feeding started on day 10 (8.9±0.07 and 10.5±0.12mm TL for L. megastoma and L. platydorsus respectively). The first posterior swim bladder aeration completed 5 days and 5 days and 6 h with 8.4±0.06 and 8.2±0.08mm TL for L. megastoma and L. platydorsus respectively and show full juvenile pigmentation and behaviour on the 41st day.

ABSTRACT. The topmouth gudgeon, Pseudorasbora parva (Temminck & Schlegel, 1842), is a small cyprinid fish that inhabits the littoral zones of freshwater habitats throughout Asia and Europe. It is regarded as an invasive species in Europe, but in its native range, in China, as food and as an environmental bio-indicator. In this study, the embryonic and larval development of P. parva was investigated for the first time. The eggs of P. parva are transparent, adhesive and elliptical. The mean size of fertilized eggs was (1.63×1.31) ± 0.04 mm. From fertilization to hatching, embryonic development could be divided into eight stages and 34 phases, and the incubation period lasted for 109.25 hours at 24 ± 1 °C. Newly hatched larvae were 4.1 ± 3 mm in length, and the yolk absorption was completed within six days after hatching. The first and second swim bladders formed at the third and ninth day, respectively. The pectoral fin formed before the hatching stage, followed by the caudal, dorsal, anal and ventral fin formation after hatching. About 20 days after hatching, the morphology of the fry was similar to the adult fish. These findings provide a basis for determining the complete ontogeny of P. parva, as well as facilitate the management and utilization of this fish.
