“…The ability to tolerate certain periods of food deprivation is crucial to larval survival and growth (Chen et al, 2007). However, food deprivation should be avoided before the complete development of the larvae, because it may damage gut cells, which are important to digestion and food absorption.…”

“…Several methods have been used to describe the effects of food deprivation in adult and larval fish: morphometric and gravimetric measurements (weight) (Peña, Dumas, 2005;Shan et al, 2009;Faria et al, 2011), RNA/DNA content (Faria et al, 2011), histological criteria (Gisbert et al, 2004), enzyme activity (Chen et al, 2007), and swimming ability (Faria et al, 2011). Available research on these issues at present is still scarce and especially targeted at fish larvae of marine species, such as Paralichthys californicus (Ayres, 1859) (Gisbert et al, 2004), Paralabrax maculatofasciatus (Steindachner, 1868) (Penã, Dumas, 2005), Seriola lalandi Valenciennes, 1833 (Chen et al, 2007), Oplegnathus fasciatus (Temminck, Schlegel, 1844) (Shan et al, 2008), and Miichthys miiuy (Basilewsky, 1855) (Shan et al, 2009).…”

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

“…Long term tissues (muscle, notochord, cartilage, and nervous system) only showed histological changes under extreme starvation suffered from starved treatment larvae and only few studies have analyzed their response to starvation (O'Connell, 1976;Uriarte & Balbontín, 1987;Pizarro et al, 1998;Catalán & Olivar, 2002;Catalán, 2003). On the other hand, short term tissues (gut, liver, and pancreas) have been widely used and probed to be more sensitive to starvation than long term tissues (Sieg, 1998;Chen et al, 2007;Diaz et al, 2011). Gisbert et al (2004) found that after two days of food deprivation P. californicus larvae showed a significant reduction in height of gut epithelial cells.…”

The use of morphological and histological features as nutritional condition indices of Pagrus pagrus larvae

et al. 2013

Morphometrical and histological techniques were employed to characterize Pagrus pagrus larvae nutritional condition. Larvae were reared in laboratory under controlled conditions with the main objective of testing whether these methodologies allowed finding differences between larvae from different feeding treatments. Once yolk was consumed (three days after hatching) larvae were assigned to a feeding treatment: starved during the whole experiment; delayed feeding, starved during three days; fed during the entire experiment. Algae (Nannochloropsis oculata) and rotifers (Brachionus plicatilis) were provided to larvae for feed treatments. Larvae were fixed daily; for morphometrical purposes in 5% formaldehyde solution, and in Bouin for histological sections. Results herein obtained showed that both methodologies are sensitive enough to distinguish larvae characterized by different nutritional condition states obtained from the feeding treatments. Consequently, these methodologies could be employed in wild red porgy larvae in order to asses their nutritional condition. These techniques could also be employed to check larval quality obtained with aquaculture purposes to estimate the effects of changes in rearing protocols or kind of food supply and thus, to guaranty a higher survival of early developmental stages of reared larvae.Con el objeto de determinar si las técnicas morfométricas e histológicas permiten diferenciar larvas en estado de inanición de las sometidas a tratamientos de alimentación, ejemplares de Pagrus pagrus fueron criados en laboratorio bajo condiciones controladas. Una vez que el vitelo fue consumido (tres días luego de la eclosión) las larvas fueron sometidas a diferentes tratamientos de alimentación: completamente privadas de alimento, privadas de alimento durante tres días y luego alimentadas, y alimentadas durante todo el experimento. Algas (Nannochloropsis oculata) y rotíferos (Brachionus plicatilis) fueron proporcionados a las larvas de los tratamientos de alimentación. Diariamente se fijaron ejemplares de los tres tratamientos en formol 5% para estudios morfométricos y en Bouin para estudios histológicos. Los resultados obtenidos dan evidencias de que las metodologías presentadas son suficientemente sensibles para determinar diferencias en la condición de larvas sometidas a los tratamientos de alimentación. Por lo tanto, podrían ser empleadas para determinar la condición nutricional de las larvas de besugo recolectadas en el mar. Por otra parte, éstas metodologías podrían ser empleadas para determinar la calidad de larvas producidas en acuicultura y evaluar los efectos de modificaciones introducidas en los protocolos de crianza o en el tipo de alimento suministrado con el objeto de mejorar la supervivencia de los estadios tempranos de desarrollo.

“…Despite the wide distribution of this species, relatively little is known about the early life history, mainly due to the fact that the spawning areas are not properly understood, and it is difficult to collect larvae and juveniles from the open sea. The use of hatchery-reared juveniles to supply the yellowtail kingfish aquaculture industry in Australia, Japan and New Zealand has recently enabled researchers to investigate some aspects of the early life-history characteristics of this species (Carton 2005, Chen et al 2007, Moran 2007, Moran & Wells 2007, Moran et al 2007a. As has been observed with larvae of other fish species, there is considerable inter-and intracohort variation in survival and growth during the early life stages of yellow-tail kingfish (Ebisu & Tachihara 1993, Chen et al 2006, Moran 2007.…”

A study was undertaken to measure the effects of conspecific density on the growth, mortality and deformity rate of yellowtail kingfish Seriola lalandi Valenciennes during the first feeding period. Newly hatched larvae were stocked in replicate tanks at initial densities of 40, 60 and 100 ind. l -1 until 30 d post-hatch (DPH). Live prey was administered at frequent intervals in an effort to maintain absolute prey density for all treatments. There was a negative relationship between conspecific density and mean individual length during the first half of the trial, which was attributed to food depletion between supplementary feedings at higher conspecific densities. The effect size (partial eta-squared) of conspecific density decreased considerably during the trial, to the point where the initial stocking density had no discernible effect on cohort growth or mortality rate. The apparent morphological deformity rate ranged from 17 to 32%, but did not differ between treatments. Jaw malformations were the most commonly observed deformity (12 to 30%). The weights of juveniles at the end of the trial were log-normally distributed, with some disproportionately large individuals skewing the weight distributions. There was substantial variation in mortality between and within treatments (74 to 97%), and the conspecific densities of each replicate at 30 DPH did not reflect the relative ordering of the initial treatments. Median individual weight was highly correlated with mortality and weight variance, and the positive skewness of populations decreased as mortality increased. Both trends indicated a strong population size-structuring mechanism. Given the controlled experimental conditions the size-structuring mechanism was not predation or cannibalism. Differential feeding success and an unidentified size-specific mortality agent are hypothesized to be the mechanisms by which mortality was able to strongly influence population size distributions.

Conspecific density is an important factor in moderating growth and survival, because it affects the intensity of competition for food and shelter and also the degree of aggression and cannibalism (Smith & Reay 1991, Hecht et al. 1996, Kotani et al. 2009). This is true both in the wild (Folkvord et al. 1994, Sakakura & Tsukamoto 1996, Smith & Fuiman 2003 and under the high-density conditions associated with aquaculture (Hecht & Pienaar 1993). The current study evaluated the effects of conspecific density on the mortality, growth and size distribution of yellowtail kingfish during the first feeding period.As is common for many marine fish species, considerable size heterogeneity develops during the first feeding phase in juvenile yellowtail kingfish, even in cohorts where the genetic parentage, age and la...
