Some positive growth differences can be observed, all year long, in Pecten maximus larvae cultivated in an old fishpond, compared with the water which flows into it periodically. These waters are filtered at 1 µm through CUNO cartridges. Moreover, the larvae are cultivated in the same light, temperature and food (cultured phytoplankton) conditions. This difference is significant in terms of larvae size, dry weight, organic matter, ashes, total proteins, glycogen, and lipids. A series of preliminary observations on the chemical composition of these two waters after filtration (amino acids, fatty acids, organic mater, nutritive salts), on the bacterial flora (total, heterotrophic organisms, vibrio), on the particular material using electron microscopy, on... |

The influence of different concentrations of four antibiotics : chloramphenicol, aureomycin, erythromycin and sulfamerazin, on the larval growth of Mytilus edulis (reared in the laboratory from the straight hinge stage on to metamorphosis) has been studied by an analytic method. The growth at once is a function of the antibiotic utilised and of its concentration in the culture vessel. The growth is rapid with erythromycin and chloramphenicol and slow with aureomycin. It is more important when the concentration of chloramphenicol increases. It is the contrary with aureomycin and erythromycin. [NOT CONTROLLED OCR] |
