| Successional progress was followed in fouling communities, developing under tropical conditions. Primary succession was simulated by immersing asbestos plates. The plates represent small, discrete, isolated parts of habitat. According with expectations, a trend of increasing space dominancy by colonial forms was detected as succession progressed. High within-habitat diversity but global persistency was confirmed for this tropical system. Several mechanisms of succession were found to operate simultaneously. In this Caribbean fouling system thestrong self-replacement tendencies of solitary forms and the low recruitment and growth rates of the potential space dominants (colonial forms) were mostly responsible for the successional patterns observed. |

| Temporal and geographical patterns of yield and selected factors affecting it: growth (von Bertalanffy K and L90: length reached after 90 days culture), survival, feed conversion rate and stocking density, were analyzed for shrimp (Penaeus vannamei) cultured in the Caribbean Colombia for the period 1991-1993. Yield did not vary between years, but it did between sites, showing the Bahía de Cispatá farm the statistically highest yield in the period considered. This pattern can be explained by the fact that shrimp there grew slowly to attain a good size, concomitantly with the highest stocking density and good feed conversion rate. In contrast, shrimp of the other sites tended to grow quicker but to stagnate at smaller sizes, stocking density tended to be... |
