<p>Arroyo Moreno (AM) is an estuarine water flow located between Boca del Río and Medellin municipalities from Veracruz State; although this estuarine habitat is situated in a state natural reserve, their environmental conditions had been altered in last decades by anthropogenic activities, which had caused changes on biotic communities including fishes. The aim of this contribution was to describe the temporal variation of fish species composition from Arroyo Moreno; an updated list of fish species was compiled for this estuarine channel, this list was made with ethnographic information provided by local fisherman using surveys, fish species catalogues, previous publications and complemented with cast net samplings. Sixty-two fish species were recorded, of these 18 were collected directly for us, another 41 species were identified by surveyed fishermen; the most abundant ecological guilds were marine temporary, freshwater temporary, and marine migrant species. With the historical fishermen’s information was inferred than both fish species richness, abundance and size had diminished noticeably in commercial fish species mainly, this outcome was related by the fishermen to the use of estuarine channel as drainage attributed to urban development in the zone.</p>

Fish Species Composition

Estuaries are critical aquatic environments that are used by many fish during their life cycle. However, estuaries often suffer from poor water quality as a result of anthropogenic activities. Fish diversity studies in estuaries are common, although few have examined whether correlations exist between water quality, metal contamination and fish assemblages. In the present study we investigated the effect of abiotic conditions, heavy metals and estuary characteristics on the abundance, diversity and composition of fish in four intermittently open estuaries along the Illawarra coast of south-eastern Australia. The heterogeneity of environmental conditions was reflected in the fish assemblages in each estuary. Environmental variables predicted fish species composition, and estuaries in particularly poor condition contained few species (estuarine residents) in high abundance, indicating their ability to acclimatise and survive in conditions that are hostile to other species. Overall, these findings demonstrate that estuarine fish assemblages may be useful indicators of estuary condition and reveal the importance of managing anthropogenic activities in the surrounding catchment to improve water quality so that biodiversity of fish can be restored in these estuarine environments.

Accurate assessments of watershed-level species composition are necessary for comparative ecological studies, ecosystem health assessments, monitoring, and aquatic conservation prioritization. Several studies have addressed sampling effort requirements for characterizing fish species composition at a section of stream, but none have examined watershed-level requirements. In the spring and summer of 2002, we extensively sampled nine Great Lakes watersheds to assess sampling-effort requirements. Sampling requirements increased with the targeted percentage of estimated species richness. Sampling 15–119 randomly selected reaches of stream, stratified by stream order, was on average sufficient to detect 80%–100% of estimated species richness. Watershed size (km2) and estimated species richness each showed a weak, negative correlation with sampling-effort requirements in our study streams, with Pearson's correlation coefficients of –5.06 and –0.590, respectively. Because of among-watershed variability in sampling effort requirements, field crews should plot species accumulation curves onsite to determine adequate inventory completion. Based on the difficulty of detecting the last 10% of species, random sampling should be conducted in conjunction with targeted sampling of rare species.
