“…The treatments that received food after the PNR kept showing high mortality and did not show a development pattern similar to the treatments that received food early (until the 5 th DAH). The capacity to resist food deprivation before the PNR depends on the larval size, temperature, and the fish species (Blaxter, Ehrlich, 1974;Houde, 1974). For example, for the freshwater species, Odontesthes bonariensis (Valenciennes, 1835), the PNR occurred on the eighth day after hatching at 26ºC (Strussmann, Takashima, 1989).…”

“…Once the endogenous reserves are exhausted, the larvae need to make a successful transition from endogenous to exogenous feeding to assure their survival and growth in that phase (Blaxter, Ehrlich, 1974). Some factors, such as availability and composition of the food (Sánchez-Velasco, 1998), temperature, photoperiod (Paul, 1983;Porter, Bailey, 2007), development of the digestive tract, visual acuity, and the swimming ability of the larvae (Makrakis et al, 2005), are important for a successful feeding transition.…”

Effects of delayed first feeding on growth of the silver catfish larvae Rhamdia voulezi (Siluriformes: Heptapteridae)

The effects of the timing of first feeding on the point-of-no-return (PNR) and growth of laboratory reared silver catfish Rhamdia voulezi larvae were studied. The experiment began immediately after the complete absorption of the yolk sac, 3 days after hatching (DAH). , and 9 th DAH. Zooplankton and newly-hatched Artemia spp. were used to feed the larvae. To evaluate the effect of food deprivation on growth, the standard length and weight of 594 larvae were assessed. Larval growth was significantly affected by the time of first exogenous feeding. The larvae fed from 3 rd to 5 th DAH showed a significantly higher development than those fed from 6 th DAH. The larvae reached the PNR on 6 th DAH. Survival and larval growth strongly depended on the timing of initial feeding. In order to avoid potential mortality by starvation and obtain good growth, the silver catfish larvae R. voulezi must establish successful initial feeding within 5 days after hatching. Keywords

“…On the other hand, a late supply of food can bring about irreversible changes in the alimentary system, as a result of exceeding the so-called point of no return (PNR), after which larvae are not able to digest ingested food (e.g. Blaxter and Ehrlich 1974). In the research carried out at 5 DPH (2 days after swim bladder inflation), 10 % of the larvae were able to take the first exogenous food (Artemia sp.…”

Dynamics of yolk sac and oil droplet utilization and behavioural aspects of swim bladder inflation in burbot, Lota lota L., larvae during the first days of life, under laboratory conditions

et al. 2013

The study concerns investigation of early larval development of burbot, Lota lota. As part of a two-year study, the first 15 days (until the end of yolk sac resorption) of burbot larvae development under controlled conditions were examined. The aim of the study was to observe the moment of swim bladder inflation and the behavioural aspects of this process, as well as the analysis of yolk and oil droplet resorption and the beginning of exogenous nutrition. It was observed that larvae began to inflate their swim bladder on the 3rd day posthatch. On 5 DPH, none of the larvae without an inflated bladder was able to swim up the distance separating it (10 cm) from the water surface. Since 9 DPH, 50 % of larvae started exogenous feeding, and the absence of yolk was observed on 13 DPH and oil droplet on 14 DPH, while on 15 DPH, 100 % of feeding larvae were observed. The presented results indicate that the analyzed period is critical for burbot, and it is characterized by a high mortality rate (over 60 %). Additionally, the results suggest that, under controlled conditions, the latest moment when burbot larvae should be given exogenous food is 9-10 DPH and until the moment of the swim bladder inflation, larvae should be kept in tanks with a low water depth (up to 10 cm). The data presented in this study could have a significant influence on the efficiency of larvae rearing, both for aquaculture and for restocking purposes.

“…There is evidence from a previous study that the distribution of prey organisms is responsible for the size-dependent vertical distribution pattern . The difference in the distribution pattern between small and large larvae during the night could also be due to size-dependent sinking speeds of herring larvae (Blaxter and Ehrlich, 1974). When light intensity falls below a critical value at dusk, herring larvae are not able to prey any longer on their food organisms.…”

“…Hence, the swimming intensity of herring larvae is reduced (Blaxter, 1968;Batty, 1987). The occurrence of larger herring larvae in deeper water layers during the night can therefore be explained by the increasing sinking speed with larvae size (Blaxter and Ehrlich, 1974). If one assumes that the herring larvae migrate actively in the vertical plane, a size dependency is also reasonable due to the better swimming ability of larger larvae.…”

SUMMARY: The distribution of herring larvae in relation to environmental conditions and the occurrence of possible prey and predator organisms was studied during a 4-day period on a permanent station in the northern North Sea in September 1999. The vertical distribution of herring larvae was sampled in 20-m intervals by means of a multiple-closing net. To resolve the small-scale patchiness of herring larvae and planktonic prey and predator organisms, a towed in-situ video system was used, the Ichthyoplankton Recorder. A diel vertical migration of herring larvae was observed with different intensities depending on their body length. Small larvae (<10 mm) were concentrated in the upper water layers during daytime and were distributed more homogenously during night time. Large larvae (>16 mm) showed the highest abundances in the upper water layers during the day and were concentrated in deeper water layers during the night. The presented results appear to be relevant for individual-based modelling of the fate of larval herring populations.Keywords: Clupea harengus, vertical distribution, larval behaviour.RESUMEN: La distribución a pequeña escaLa y La migración verticaL de Larvas de arenque deL mar deL norte (Clupea harengus, teLeostei: cLupeidea) en reLación con factores abióticos y bióticos. -Se han estudiado la distribución de las larvas de arenque en relación a las condiciones ambientales y la incidencia de posibles presas y organismos depredadores a lo largo de un periodo de 4 días en una estación permanente situada en el Mar del Norte en septiembre de 1999. La distribución vertical de las larvas de arenque fue muestreada en intervalos de 20 m mediante una red de apertura múltiple (multiple opening/closing net). Para determinar a pequeña escala la heterogeneidad en la distribución de las larvas de arenque, así como de las presas y depredadores planctónicos, se utilizó un sistema de vídeo in-situ (The Ichthyoplankton Recorder). Se observó una migración vertical nictimeral con diferentes intensidades dependiendo de la longitud corporal de las larvas. Las larvas pequeñas (<10 mm) se concentraban en las capas superiores de la columna de agua durante el día y se distribuían más homogéneamente durante la noche. Las larvas más grandes (>16 mm) mostraban su mayor abundancia en las capas superiores de la columna de agua durante el día y se concentraban en capas de agua más profundas durante la noche. Los resultados presentados en este trabajo pueden ser relevantes para la modelización (individual based modeling) del destino de las poblaciones de larvas del arenque.Palabras clave: Clupea harengus, distribución vertical, comportamiento de las larvas.
