CAPTIONS
Fig. 1. | Map of the Venetian Lagoon, showing the Locations of Valle SPARESERA (I) and Valle FOSSE (2). |
Fig. 2. | Planimetric map of Valle SPARESSERA showing the ponds used for the production experiment. The arrows indicate the direction of water flow caused by the tide and pumping system. |
Fig. 3. | Schedule for the pond fertilization program (ponds A, B, C, D, E, F) throughout the whole experiment, from pond preparation to just before harvesting. |
Fig. 4. | Nutrient content measurements at the moment ponds D was fertilized in Valle SPARESERA. The arrows indicate the dates on which the fertilizations were carried out. |
Fig. 5. | Nutrient content measurements in Valle FOSSE. The arrows, left, indicate the sole date on which fertilization was effected (organic + inorganic) |
Fig. 6. | Water temperature readings in pond D in Valle SPARESERA. |
Fig. 7. | Histogram of the phyto and zoo-planktonic biomasses given in wet weight, with corresponding chlorophyll a curve in a Valle SPARESERA. It also shows the qualitative composition of the most representative species of the community. |
Fig. 8. | Histogram of the phyto and zoo-planktonic biomasses given in wet weight, with corresponding chlorophyll a curve in Valle FOSSE. It also shows the qualitative composition of the most representative species of the community. |
Fig. 9. | Transparency curves of the water in pond D in Valle SPARESERA and pond F in Valle FOSSE using the SECCHI disk. The arrows indicate the dates of Fertilization; the last arrow, right, (coloured white ), shows the final fertilization, which was not applied to pond D. |
Fig. 10. | Histograms of the macrobenthonic biomasses given in wet weight in pond D, Valle SPARESERA, and pond F, Valle FOSSE; The qualitative composition of the main zoological groups are given for these biocenoses. The curves express the fractions of the biomasses actually used by the penaeids, namely, annelids, crustaceans and insects taken together, and the soft parts of the mollusks that they are able to attack (Hydrobia sp and others), and the Cerastoderma glaucum under 3 mm in size. |
Fig. 11. | Curves showing the weight increases of the populations of Penaeus japonicus in pond D and F in the Valle SPARESERA and Valle FOSSE, respectively. |
