Larval rearing and weaning of seabass, Lates calcarifer (Block), on experimental compounded diets
Provedor de dados: 5
Autores: Fuchs, Jacques; Nedelec, Georges.
Larval rearing trials of seabass larvae, either imported from Singapore or obtained from the captive broodstock of IFREMER/C.O.P. at Tahiti, were carried out since 1987, by testing different technologies originally used in South East Asia (green-water culture, sequential water changes) or developed by IFREMER for other species (clear water system, preys enrichment, continuous water renewal).

Problems related to the lack of functional swimbladder in intensive rearing of the seabass Dicentrarchus labrax and the sea bream Sparus auratus .
Provedor de dados: 5
Autores: Chatain, Beatrice.
The primordial inflation of swimbladder normally occurs at a size of 4 to 5 mm in sea bream Sparus auratus and 5 to 6 mm in sea bass Dicentrarchus labrax . However, in intensive larval rearing conditions, lack of inflation is often observed and leads to the production of up to 80% of postlarvae whose swimbladder is not functional. They are, on the average, 20-30% smaller in weight than normal fry. Their survival rate can also be reduced by any kind of stress such as weaning, handling or hypoxic conditions. It is suggested that the selective mortality which affects the abnormal fish results both from a decrease in predatory efficiency and an increase in energetic needs.

Ontogenetic development of tetra Astyanax lacustris (Characiformes: Characidae)
Provedor de dados: 83
Autores: Stevanato,Diego J.; Ostrensky,Antonio.
ABSTRACT Ontogenetic development of the tetra Astyanax lacustris was studied under laboratory conditions. Larvae obtained by induced reproduction were maintained individually in tissue-culture plates, at 25°C. Daily observations and morphometric measurements were performed. Larvae hatched with a total length (TL) of 3.02 ± 0.34 mm (average ± standard deviation) without pigmentation and 0.06 ± 0.02 mm³ of yolk reserves. The yolk-sac larval period lasted 26 h post-hatching (hph). During this period, eye pigmentation started, the digestive tract emerged, the anus opened, and the animals began to show steady movements. Inflation of the swimming bladder initiates the preflexion stage, which extended until 230 hph. During this stage, the transition from...

The life cycle of &lt;i&gt;Anguillicola crassus&lt;/i&gt;
Provedor de dados: 27
Autores: De Charleroy, D.; Grisez, L.; Thomas, K.; Belpaire, C.; Ollevier, F.P.
For some years now the parasitic swim bladder nematode &lt;i&gt;Anguillicola crassus&lt;/i&gt; of the European eel &lt;i&gt;Anguilla anguilla&lt;/i&gt; L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...

Paratenic hosts of the swimbladder nematode &lt;i&gt;Anguillicola crassus&lt;/i&gt;
Provedor de dados: 27
Autores: Thomas, B.; Ollevier, F.P.
The host specificity and population dynamics of &lt;i&gt;Anguillicola crassus&lt;/i&gt; in a number of paratenic hosts were investigated. Various freshwater fish species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and examined for L&lt;sub&gt;3&lt;/sub&gt;-larvae of &lt;i&gt;Anguillicola crassus&lt;/i&gt;. Sixteen species were found to be infected: all the physoclist species examined (&lt;i&gt;Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus&lt;/i&gt; and &lt;i&gt;Perca fluviatilis&lt;/i&gt;) and those physostome species of which a sufficient number could be examined to detect the infection (&lt;i&gt;Gobio gobio, Leuciscus...
