“…In the present study, at least 3 spa-119 tial groups were discriminated, corresponding to areas of high and low hydrodynamic impact, similar to the zonation patterns found at Zuma Beach, California (Morin et al 1985) and Masnou Beach, Spain (Munilla & Vicente 2005) for the subtidal communities along a depth gradient. Occupying more hydrodynamic areas (1.3 to 3.4 m depth), composed by fine to medium sands, were some crustaceans adapted to environmental stress (such as the hermit crabs), which agrees with other surf zone studies (Vicente & Sorbe 1999, Beyst et al 2001a, Connor et al 2004, Janssen & Mulder 2005. These depths presented the lowest species number and density, which was also reported by Morin et al (1985), Jansen & Mulder (2005) and Munilla & Vicente (2005) at the shallow, more hydrodynamic areas down to 7 m depth, beyond which the species richness increased (water depths shallower than 30 m).…”

“…Less frequent are the studies on the swash, surf (Vicente & Sorbe 1999, Beyst et al 2001a and sub-littoral areas (Morin et al 1985, Hernández-Arana et al 2003, Wieking & Kröncke 2003, Connor et al 2004, Hoey et al 2004, Janssen & Mulder 2005, due to constraints in the sampling procedures near the wave breaking and sub-littoral regions. In these areas, the sediment texture and dynamics are assumed to have a major role in the structure of the benthic community (Snelgrov 1998, Miller et al 2002, Hoey et al 2004).…”

The subtidal macrobenthic community of a temperate beach in southern Portugal was studied along a depth gradient (1.3 to 32 m deep), which was long enough to comprise both highly hydrodynamic and calmer areas, to assess the influence of the spatial and temporal differences in hydrodynamic impact at the seafloor on the organization of a macrobenthic community. These differences were assessed by studying the variations in wave climate, depth of closure and extension of the mixed profile. A spatial zonation was detected from highly hydrodynamic shallow depths, 7.2 m deep shorewards, to the calmer deeper areas, from 8.4 m seawards. Accordingly, in the shallowest depths, species richness and densities were lower, with the inhabiting species, mainly crustaceans and surf clams, adapted to the environmental severity. Both species richness and densities increased along the depth gradient, and the community became dominated by polychaetes, nematodes and nemerteans. Seawards, within the relict sediments (deeper than 25 m), species richness and abundance decreased again. The community patterns also changed in response to the occurrence of strongly hydrodynamic episodes (such as storms), which had a higher impact than the seasonality. It was concluded that harsh physical environmental conditions reduce species richness, both spatially and temporally. With respect to density, other parameters related to life cycle characteristics, recruitment success and biotic interactions may also have some impact. 352: 113-124, 2007 port, varying with large and small spatial changes in hydrodynamics (Hewitt et al. 2003). Seasonal differences in the hydrodynamics or punctual disturbance events, such as storms, may be an important conditioning for the benthic community (Hernández-Arana et al. 2003). The wave climate impact on the sea bottom can be expressed in terms of the depth of closure (D c ), i.e. the depth below which limited sediment transport due to wave action is expected to occur (Nicholls et al. 1998). Thus, the D c separates the active cross-shore profile from a deeper zone where the sediment transport is much weaker and morphological changes are less perceptible. As a result, the D c can be seen as a proxy of the wave energy acting at a given shoreface. Deeper values of D c are associated with higher wave energy levels and sediment exchanges, while shallower values result from lower wave energy and consequent smaller degree of sediment transport and morphological changes. The macrobenthic community existing at the nearshore must be able to adapt to the different wave energies and to the consequent sediment mixing, resulting in changes to the spatial and temporal distribution patterns.

“…Bioindicators and biotic indexes are being used by Europeans to assess water quality of water bodies [24] for last 100 years. Potentiality of zooplankton as bioindicator is very high because their growth and distribution are dependent on some abiotic (e.g., temperature, salinity, stratification, pollutants) and biotic parameters (e.g., food limitation, predation, competition) [7][8][9] . Another study [11] in river Ramjan of Bihar, India revealed that abiotic parameters (e.g., pH, transparency, temperature, dissolved oxygen and some micronutrients) in relation to seasonal fluctuation influence zooplankton abundance.…”

Problem statement:This review tended to summarize some recent research on zooplankton as bioindicator in India and some other countries of the world. Approach: These researches were mainly on fresh water bodies. Results: Qualitative as well as quantitative analysis were done by Shannon diversity index (H'), Evenness index (J), Species Richness index (S) and Saprobic index. In most of the cases zooplankton population size was correlated with biotic and abiotic parameters (pH, alkalinity, temperature, dissolve oxygen, transparency, phosphate, chlorine). Species of Rotifers, Cladocerans, Copepods and Ostracods were found in all cases. Species variation of these order deceased in polluted water. Some species were not found in some highly polluted area though these species have high tolerance level. Conclusion/Recommendations: All the results of the studies indicated that potentiality of zooplankton as bioindicator is very high. Other countries can develop these concepts to monitor water quality.

“…They are used as live feed to rear many difficult species which feed exclusively on live feed. Mysids of different size range are found suitable as live-feed in the larval rearing of newly hatched squid and cuttlefish larvae (Domigues et al, 2001;Nabhitabhata, 1996;Anil, 2003), nursery rearing of ornamental fishes, food-fishes and serve as livefeed for many other marine organisms (Beyst et al, 2001), thus acting as a trophic link between primary producers and secondary consumers. Mysids are omnivorous and cannibalistic, feeding on diatoms and small crustaceans such as copepods (Odum and Herald,1972;Mauchline,1980).…”
