Ascophrys rodor (Campillo and Deroux) parasite of the reared common prawn P. serratus). ArchiMer
Deroux, G.; Campillo, Albert; Bradbury, Ph. C..
A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical...

Contribution à l'étude de la crevette rose Palaemon serratus (Pennant) : Exploitation, Biologie, Elevage, Epidémiologie ArchiMer
Campillo, Albert.
This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast. Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations. The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between...

Contribution a l'etude de l'elevage de la crevette rose Palaemon serratus (Pennant) en captivite. ArchiMer
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...

Developpement embryonnaire de Palaemon serratus : Resultats preliminaires ArchiMer
Bellon, H.
The formation of the limbs, the digestive tract, the nervous system, the sensory and hormonal structures begins in this prawn during the embryonic stage C, according to Richard's definition (1974) and is performed at the stage H. The digestive tract differentiates with a caudo-cephalic gradient. The digestive gland is formed at least partially by vitellophages. The C.N.S. appears with a cephalo-caudal gradient and the regions of the eyestalk are quickly differentiated. The organ of Bellonci and the sensory pore appear independently during the stage F. The first neurosecretory cells are detected in the brain during the stage D.

Etude de la Sensibilite Thermique des Larves du Crustace Decapode : Palaemon Serratus (Pennant). ArchiMer
The whole of experiments carried on from thermal constraints on the larval development of Palaemon serratus allows the following observations: -individual rearings obtain the best survival rates in the witness groups and neutralize by a dense food and the absence of intraspecific cannibalism, factors which can interfere with the results ascribed only to the experiments; - slight thermal increases (10 and 12 degree C) do not involve secondary effects on the post larvae when the development is realized at 20 degree C; - if the TL 50 is reaching 34 degree C, letal effects are observed, as soon as the final temperature; - whatever is the temperature increase, the relation = mortality/temperature reached is similar and this factor mortalities observed, that...

Evolution des acides nucleiques au cours du developpement larvaire de la crevette rose Palaemon serratus (Pennant). ArchiMer
Campillo, Albert; Regnault, M.; Luquet, P..
The evolution of nucleic acids in larvae of P. serratus reared in the laboratory from hatching to metamorphosis has been studied. From the 1st larval stage to the post-larval stage, DNA and RNA concn decrease: from 185 to 95 uMoles-bases/g PSD for DNA and from 133.5 to 78.75 uMoles-bases for RNA. The concn decrease is not regular; it is emphasized between stages 4 and 5 on the one hand, and between stage 7 and the post-larva on the other hand. The amount of DNA and RNA per larva increases proportionally to the wet weight from stage 1 to the post-larva. As the weight is multiplied by 7.6, total DNA and total RNA are multiplied by 3.80 and 4.25 respectively. The RNA/DNA ratio has a mean value of 0.77; it increases slightly from stage 1 (0.72) to the...

Histogenese de l'organe Y (glande de mue) chez l'embryon de la crevette Palaemon serratus (Pennant) (crustace decapode Natantia) ArchiMer
Leroux, A.
The Y organ appears during the embryonic development of the prawn (P. serratus ) at a stage approximately C, according to Richard's definition (1974). 3 weeks separate this stage from hatching at a temperature of 20 degree C. The organ formation is realized over 48 hours and is marked by an histological modification and a small mitotic crisis in the epidermal tissue from which it differentiates. Its metameric localization is mainly maxillular.

In order to estimate the effects of chlorine used in cooling systems of electric power plants on zooplankton, some experiments have been realized with the four first larval stages of the prawn (P. serratus Pennant). Chlorine injection was performed by constant adding at 16 and 20 degree C with times exposures of 5, 15 and 25 minutes. If there is no detectable variations in sensitivity of different stages, toxic effects of oxydants issued from chlorination can be observed (for both the two acclimatation temperatures) at 15 minutes exposure with a LD 50 : 32 mg/l of chlorine.

Influence du taux de proteines sur la croissance ponderale de Palaemon serratus (Pennant) elevee au laboratoire ArchiMer
Campillo, Albert; Luquet, P..
The quantitiative requirements for protein have been determined in P. serratus reared from the post-larval stage to the 4th month. It appears that the apparent optimum percentage of protein in the diet is a minimum of 60%. At the 8th month, the mean wt of prawn reared with the best artificial diet (diet IV) is only 49% of the wt of shrimp reared with the digestive gland of Patella as a diet. The prawns reared to 4th month on a low-protein diet then reared on a natural diet until the 8th month, show important compensatory growth. However, the prawns do not achieve the wt of the control population, their average wt representing only 16% of the controls.

Variations des activites digestives en fonction des facteurs du milieu chez les crustaces ArchiMer
Galgani, Francois; Benyamin, Y; Vanworhmoudt, A; Cecaldi, J.
Proteolytic enzymes of hepatopancreas of six species of peneids (Penaeus kerathurus, P. japonicus, P. monodon, P. stylirostris, P. merguiensis and P. vannamei ) have been studied. Some of their physiological variations have been characterised. Increase in acclimation temperature of crustaceans enhances increase of specific activities of proteases. Variations of salinity does not modify specific activities, nor quantities of trypsin, nor electrophoretic patterns of these different proteases.
