1. A simple cylindrical hatching and separator box is described for Artemia salinanauplii (and other phototactic invertebrates), in which the "corner seeking effect" responsible for poor separation is avoided, and from which nauplii can be recovered very conveniently. 2. Separation is achieved by partly unscrewing an internal and closed cylinder from its fixed counter-part glued to the bottom of the box, till two slits are freed through which the nauplii migrate from the darkened internal hatching cylinder into the illuminated exterior compartment. Rescrewing the former cylinder separates the larvae from debris and unhatched eggs.

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives

Campillo, Albert.

The growth of post-larval P. serratus has been studied until the appearance of secondary sexual characters, in order to eliminate the influence of sex ratio on the mean wt. The influence of temp on intermolt period and number of molts was observed in male and female kept individually. Different sorts of food of natural origin have been tested. The rearing of post-larval lots metamorphosed at different times of the yr showed that the growth of P. serratus is conditioned not only by the temp, but also by the season. The food conversion ratio was defined in relation to the sex and age of the prawns. Shelters allowed the author to obtain a ratio of survival which varied post-larvae per square meter. The sex ratio established from several breedings as soon as...

Effect of incubation system on the development of intestinal villi, metabolism, and performance of one- to forty-day-old broiler chickens

Person, L.

Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

ABSTRACT An experiment was performed to evaluate the effect of the incubation system ― multiple-stage (MS) and single-stage (SS) ― on the characteristics at hatching, intestinal morphology, metabolism, and performance of Cobb-500 chickens from 1 to 40 d of age. A total of 1,968 fertile eggs were incubated in two setters under commercial conditions. Birds hatched in SS were longer than those hatched in MS, and the females had higher relative intestinal weight compared with males. However, at hatching, there were no differences in BW and yolk-free body mass from incubation system or sex. In the period from 1-40 d, the birds hatched in SS were heavier, had higher weight gain and better adjusted feed conversion, without differences in feed intake and feed...

ABSTRACT The aim of this study was to evaluate the effects of in-ovo vaccination on different incubation days of broiler embryos derived from young and old breeders on incubation indexes, vaccine response, and broiler performance. A number of 20,160 fertile eggs was distributed according to a completely randomized design in a 4 x 2 factorial arrangement (in-ovo vaccination on 16, 17, 18, or 19 days of incubation, and breeders of 31 or 52 weeks of age), totaling eight treatments with 15 replicates of 168 eggs each. Vaccination procedures and vaccines (strains and doses) were those routinely applied in commercial hatcheries. After hatch, 960 male chicks were housed and distributed according to the same experimental design previously applied in the hatchery....

ABSTRACT Inland waters experience extreme environmental conditions determining the evolution of several adaptive strategies of the fauna to these variable conditions. Freshwater sponges produce resisting bodies called gemmules that contain totipotent cells and specialized spicules (gemmuloscleres). Completely formed gemmules exhibit low metabolic rates and may become dormant during periods of environmental stress. Until now, few species had their hatchability tested against different environmental conditions. The purpose of the present study was to test the capacity of hatching gemmules of two freshwater sponge species (Heteromeyenia cristalina Batista, Volkmer-Ribeiro & Melão, 2007 and Radiospongilla inesi Nicacio & Pinheiro, 2011) from inland...

The influence of age (85, 140, and 270 days) of European quails breeders on the egg quality and hatching, fertility and progeny performance was evaluated. The experimental design was completely randomized in a 3x3 factorial arrangement (females' age x males' age), with ten replicates and six birds per experimental unit (four females and two males). Egg production and quality were determined during 3 periods of 14 days and incubation parameters were evaluated in eggs obtained in five consecutive days. The live performance of the progenies was analyzed until 35 days. There was no effect of male age or any interaction between the age of males and females for the evaluated variable. The female's age influenced egg production, egg weight and chick weight, with...

International study on Artemia : 15. Effect of light intensity on hatching rate of Artemia cysts from different geographical origin

Vanhaecke, P.; Cooreman, A.; Sorgeloos, P..

Artemia cysts from 4 geographical strains were incubated under standard hatching rates increased with increasing light intensities. The light-intensity threshold at which the maximal hatching rate was attained, varied from strain to strain. Differences in light sensitivity between the Artemia strains studied can, at least partly, be attributed to variation in chorion characteristics. The hypothesis is discussed that light might act as a diapause inhibitor in marine and freshwater branchiopods.

Vanhaecke, P.; Sorgeloos, P..

A comparative study has been carried out on the hatching rate of Artemia cysts of different geographical origin and on different batches of the same source. Substantial variation, among as well as within geographical strains, indicates that the hatching-rate criterion is not strain specific. In an attempt to identify the parameters which influence the hatching rate, it was found that the cyst-drying technique as well as the storage conditions may significantly affect this criterion. It has also been demonstrated that the cysts' hatchability is influenced by their previous drying and storing conditions. Optimal hatching results are guaranteed when a fluidized bed dryer is used and the cysts are stored under vacuum or nitrogen.

Vanhaecke, P.; Sorgeloos, P..

A comparative hatching study has been carried out with reference Artemia cysts as well as cysts from Argentina, Australia, Brazil, Canada, France, Italy, the People' s Republic of China, the Philippines and the USA. Hatching rate, percentage and efficiency vary considerably from one cyst source to another. These hatching criteria are, however, not strainspecific since significant variation is found among cyst batches from the same geographical origin. The limitations of the "hatching efficiency" concept are discussed and a new criterion "hatching output", i.e. the biomass of nauplii expressed in mg dry weight produced per gram cyst product, is proposed for evaluation of the hatching quality of Artemia cyst brands. The...

Using cyst material produced in an indoor cyst production system from 4 Artemia strains belonging to the species A. franciscana (San Francisco Bay, California, USA; Macau, Brazil; Great Salt Lake, Utah, USA) and A. parthenogenetica (Lavalduc, France), different factors were studied that affect dormancy in brine shrimp cysts. Preliminary experiments under varying (a)biotic culture conditions revealed an interaction between environmental conditions and hatching characteristics. Results obtained under better-defined conditions demonstrated a significant positive correlation between the amount of food available to the adult Artemia populations and the hatchability of their encysted...

L’implantation récente de Rapana venosa, gastéropode prédateur originaire d’Extrême Orient, en plusieurs points du globe (USA, France, Uruguay, Argentine) et son impact sur les populations de bivalves autochtones justifient un certains nombre de recherches engagées par les pays concernés. Le présent rapport compile les dernières informations scientifiques disponibles sur la biologie de R. venosa. Par ailleurs, l’opportunité d’obtenir des pontes en milieu naturel et en captivité en 2001 a permis de faire des observations sur la maturation des larves. Il apparaît que dans les conditions de températures régnant en Baie de Quiberon en été (18 à 22°C), les larves de Rapana venosa sont capables d’éclore.

Lethal temperatures for Rhamdia quelen larvae (Pimelodidae)

Ciência Rural

Chippari-Gomes,Adriana Regina; Gomes,Levy Carvalho; Baldisserotto,Bernardo.

The lower and upper lethal temperatures (LT50) of R. quelen larvae were determined. The larvae were obtained from two spawning periods with hatching temperatures of 21 and 26ºC respectively. Larvae were placed in tanks at which the temperatures were either increased 1ºC every 15min, or reduced 1ºC every 20min until larval movement ceased. This temperature was then maintained for 96h. Minimum mortality (29.0 ± 1.5%) was observed in the larvae held at hatching temperatures. The lower LT50 were 15.01 and 16.72ºC, and the upper LT50 were 29.25 and 27.83ºC for the larvae hatching at 21 and 26ºC, respectively. Thus, apparently there is no difference with relation to temperature change tolerance between larvae hatched in both temperatures.

Metaplasia in swim bladder epithelium of the endangered annual fish Austrolebias nigrofasciatus (Cyprinodontiformes: Rivulidae) results in inadequate swimming and delayed growth

Suquet, Marc; Dreanno, Catherine; Petton, Bruno; Normant, Yvon; Omnes, Marie-helene; Billard, Roland.

The survival of turbot eggs and the rearing capacities of larvae stemmed from artificial fertilization practices using frozen-thawed spermatozoa were evaluated. Furthermore, the viability of sperm samples stored during a 9 month period in liquid nitrogen was assessed. No significant difference in the fertilization rate, hatching rate, survival and wet weight of 10-day old larvae were observed using fresh or frozen-thawed spermatozoa. The motility recorded at 10 s and 60 s post-activation and the fertilization capacity of frozen-thawed spermatozoa were not significantly decreased during a 9 month storage period in liquid nitrogen. These results confirm the high quality of the turbot spermatozoa stemmed from the cryopreservation process, allowing their use...

ABSTRACT Laboratory breeding of annual fish is often impaired when fish fail to inflate the swim bladder after hatching. These fish, which are known as belly-sliders, cannot swim in the water column, moving mainly on the bottom of water. Therefore, we wanted to understand the factors underlying failed inflation of swim bladder in the annual fish Austrolebias nigrofasciatus and determine the implications of this condition on the growth of juveniles. To identify how the initial filling of the gaseous vesicle is compromised, and to determine the implications of this condition on juvenile growth, we analysed the histology of the swim bladder of both normal swimming fish and belly-sliders during their initial growth phase (first month of life). In addition to...

Enrichment of culture media with amino acids improves embryo development. However, little is known about the specific action of each amino acid during embryogenesis. The present study was undertaken to examine the effect of L-glutamine (Gln) and tryptophan (Trp) on mouse embryo hatching, expansion and viability in vitro. Blastocysts were collected from 6- to 8-week-old female BALB/c mice (N = 30) and cultured in M2 medium containing either 0.125, 0.25 or 0.5 mM Trp, 1 mM Gln, or M2 alone. Gln significantly increased (100%; P < 0.05) blastocyst hatching at 24 h compared to M2 alone or Trp; moreover, Trp inhibited blastocyst hatching when compared to M2 alone (P < 0.05) at 72 h. In contrast, the percentage of embryos reaching the state of expanded...
