Abstract

Complex habitats benefit organisms by providing refuge from predators, foraging, and stress reduction. Juveniles are particularly vulnerable and rely on complex habitats as nurseries. Many studies have assigned nursery value to habitats based on juvenile abundances, rather than growth and recruitment to adult populations. Nearly all such studies have compared habitat types, rather than within habitat variation. The purpose of this study was to determine the potential value of different seagrass, submerged aquatic vegetation (SAV), densities as well as shrimp densities to growth of juvenile brown shrimp, Farfantepenaeus aztecus (Ives, 1891). Experiments in tanks examined effects of non-vegetated bottom (NVB) and artificial SAV densities and different shrimp densities on growth. Measurements included total length, dry weight, and body composition of protein, lipid, and carbohydrate. Presence and density of artificial SAV density did not result in greater growth or changes in body composition; however, individual growth and carbohydrate reserves decreased significantly with increasing shrimp density. While individual growth decreased, total biomass produced was greatest in tanks with high shrimp densities. While the value of SAV should not be reduced, it appears that the value of NVB to juvenile brown shrimp may have been ignored by previous studies.
