“…do Sui, however, on the average, the weight biomass was greater during the daytime collections. This result differed from those obtained by LASIAK (1984) and GIBSON et of. (1993), who observed higher weight biomass during the low tide nighttime.…”

“…The greater diversity in the low tide catches, independent of the time of day, observed at Pontal do SuI, was also present in the collections of DELANCEY (1989) on the American East coast. While the ichthyofauna ofPontal do SuI, apparently, maintains between daytime and nighttime species composition, in other beaches this species composition appears to change between these periods (LASLAK 1984;GIBSON et of. 1993).…”

ABSTRACT. Fishes were sampled by beach seine during the day and night at the high and low sygygy tides, on asandy beach at the southeast coast ofBrazil. The quantitative results appear to indicate a larger concentration of fish in the surf zone of this beach, in low tides at the start and end of the day. Only eight from the 17 most abundant taxa, appeared to have been influenced singly or in combination by the factors ofthe moon, day, night and tide.

“…However, the viability of these indexes should be tested within each biological context. For example, it should be possible to distinguish the natural seasonal movements of the ichthyofauna related to their recruitment and reproduction patterns (Gibson et al, 1993;Pessanha et al, 2003;Félix et al, 2007;Félix-Hackdart et al, 2010) from other fluctuations resulting from stochastic variations or anthropogenic impacts, in addition to how the indexes respond to these changes.…”

ABSTRACT. We use two taxonomic indexes to assess the variability of the taxonomic structure and diversity of the ichthyofauna of two low-energy environments in southern Brazil and to compare the temporal patterns of these two ichthyofaunas. Sampling was conducted in the infralittoral zones of Maciel (Paranaguá Bay, PR) and Indio Beach (Norte Bay of Florianópolis, SC). A fyke net was set up at a depth of 0.5 to 2.0 m and left in place for 48 h for each of the samplings. A total of two diurnal and two nocturnal samplings were conducted monthly per one year. The ichthyofaunas at the two sites exhibited similar temporal dynamics, with their abundance and biomass presenting a tendency to increase with increasing temperature during the spring and summer months. A total of 113 species were captured, of which 47 were present at both sites. Harengula clupeola, Sphoeroides testudineus and S. greeleyi were especially abundant at both sites. The co-occurring species displayed similar day and night occupancy trends. In all seasons, the obtained values for the average taxonomic distinctness and variation in taxonomic distinctness were within the confidence intervals. The seasonal reproduction and recruitment patterns led to slight changes in taxonomic distinctness during the year, which were within the expected intervals. Keywords: ichthyofauna, taxonomic distinctness, nycthemeral dynamics, sheltered beach, southern Brazil.Comparación de los patrones taxonómicos y temporales de la ictiofauna capturada con red fyke en dos ambientes protegidos en el sur de Brasil RESUMEN. Se utilizaron dos índices taxonómicos para evaluar la variabilidad de la estructura taxonómica y diversidad de la ictiofauna en dos ambientes de baja energía en el sur de Brasil, así como para comparar sus patrones temporales. Los muestreos se realizaron en las zonas infralitoral de Maciel (Bahía de Paranaguá, PR) e Indio Beach (Bahía Norte, SC). Se instaló una "fyke net" a una profundidad de 0,5 a 2 m, durante 48 h, para cada uno de los muestreos. Durante un año se realizó un total de dos muestreos diurnos y dos nocturnos. La ictiofauna en los dos sitios mostró dinámicas temporales similares, con su abundancia y biomasa presentando una tendencia a aumentar con el incremento de la temperatura durante los meses de primavera y verano. Un total de 113 especies fueron capturadas, de los cuales 47 estuvieron presentes en ambos sitios. Harengula clupeola, Sphoeroides testudineus y S. greeleyi fueron especialmente abundantes en ambos sitios. Las especies coexistentes mostraron tendencias similares de ocupación tanto de día como de noche. En todas las estaciones, los valores obtenidos para la distinción taxonómica media y para la variación en la distinción taxonómica estuvieron dentro de los intervalos de confianza. Los patrones de reproducción y reclutamiento estacionales llevaron a ligeros cambios en la distinción taxonómica durante el año, que estuvieron dentro de los intervalos esperados.

“…A great variety of organisms live in such habitats and fishes and crustaceans play important roles in these communities (Brown & McLachlan 1991). In northern Europe, the numerically dominant macrofauna consists of a few fish species, especially plaice Pleuronectes platessa and gobies of the genus Pomatoschistus, and 2 crustaceans (Crangon crangon and Carcinus maenas) (Macer 1967, Pihl & Rosenberg 1982, Evans 1983, Gibson et al 1993. Here, as in many other similar nursery habitats, juvenile stages predominate and their small size renders them vulnerable to a wide variety of predators .…”

The distribution and movements of juvenile plaice Pleuronectes platessa and their potential predators and competitors were recorded in a small microtidal (-20 cm) bay on the west coast of Sweden uslng underwater television and conventional nettlng techniques. There was generally close correspondence between the results obtalned by the 2 methods. Young plaice moved upshore at dusk and returned to deeper water at dawn. Larger predatory fishes also moved upshore at night but not as far as the plaice; they also entered shallow water later and left for deeper water earlier than the plaice. One interpretation of these nocturnal upshore migrations by plalce, therefore, is that they minimse predation risk. Although stomach fullness was greater at night, the availability of suitable food items for the plaice throughout the bay makes it unl~kely that the upshore movements were solely related to feeding. Because there was a strong diel temperature fluctuation In the bay, such movements also ensured that the fish remained in a fairly constant temperature. The main competitor of the plaice for food in July, the shrimp Crangon crangon, showed no such migratory movements and was mostly active during the day. The other dominant large crustacean (Carcinus maenas) was nocturnally active and did not markedly change its depth distribution over the 24 h period. The observed patterns of movement suggest that the timing of immigration and emgration is mainly triggered by changes in light intens~ty because only in C. rnaenas was any relationship found between activity and the phase of the tidal cycle.
