“…This observation is supported by recent studies in New Zealand (Morrison et al, 2002), Germany (Thiel and Potter, 2001), the northeastern United States (Able and Fahay, 1998;Hughes et al, 2002;Hagan and Able, 2003;Lazzari et al, 2003) and California (Allen et al, 2002;Desmond et al, 2002;Matern et al, 2002). The five or fewer most abundant species in these systems are low in the trophic structure as would be expected from general patterns of relative abundance at different trophic levels.…”

“…In their survey of 26 European estuaries, Pihl and co-workers found that more than 60% of the fish species recorded in these habitats were using them as nurseries. Numerous recent publications on bay-estuarine, salt marsh, and other near shore coastal fishes contain "nursery" in the title, an indication of the continued importance of evaluating this function in shallow-water habitats (e.g., Forrester and Swearer, 2002;Gillanders et al, 2003;Lazzari et al, 2003;Minello et al, 2003). In California, most of the sampling studies of bay-estuarine fish assemblages mention the importance of the nursery function and often that a large proportion of the catch were juveniles (e.g., Yoklavich et al, 1991;Matern et al, 2002).…”

“…Similarly, the majority of individual species were only represented by juveniles, which brings out the role of the Pando estuary as a nursery site. In fact, many authors (e.g., POTTER et al, 1990;ROUNTREE;ABLE, 1992;LAZZARI et al, 2003;VEIGA et al, 2006;MARTINHO et al, 2007) have previously reported that estuaries and salt marshes are important for many fish species by providing food and nursery areas, shelter and protection from large piscivorous fishes WHITFIELD, 2000;ELLIOTT et al, 2002). This is consistent with studies of estuarine fish worldwide, as most estuarine fish communities are dominated by juvenile stages (BLABER; BLABER, 1980;POTTER et al, 1990;VALESINI et al, 1997;WHITFIELD, 2000).…”

Fish assemblage in a temperate estuary on the uruguayan coast: seasonal variation and environmental influence

2010

A B S T R A C TThe seasonal dynamics of the fish community in the Pando estuary on the Uruguayan coast were studied in relation to environmental sampled monthly between May 2002 and June 2003. Individuals collected were identified, and classified into stages (juveniles, adults) and functional groups. Relationships between community dynamics and environmental variables were evaluated using uniand multivariate techniques. Twenty-one species, mostly freshwater stragglers, estuarine and marine migrants were collected. The most abundant species were Micropogonias furnieri, Mugil platanus, Paralichthys orbignyanus and Brevoortia aurea and were represented by juveniles. The community varied seasonally with rapid shifts in spring and autumn associated with changes in temperature and salinity. Significant correlations between abundance and temperature may be related to the timing of life cycle events. In this estuary, the salinity appears to play a key role in the functional structure and in the use of the habitat by juveniles. This is relevant for the definition of estuaries as nursery areas: this definition is context-dependent and is determined by the salinity conditions. R E S U M OFoi estudado a dinâmica sazonal da comunidade de peixes em relação as variáveis ambientais do estuário Pando, localizado na costa uruguaia. Os peixes foram amostrados mensalmente entre maio de 2002 e junho de 2003. Os indivíduos coletados foram identificados e classificados em estágios (jovens, adultos) e grupos funcionais. Relações entre a dinâmica da comunidade e as variáveis ambientais foram avaliadas utilizando-se técnicas uni-e multivariada. Vinte e uma espécies foram coletadas, principalmente visitantes de água doce, estuarinas e marinhas migratórias, sendo as mais abundantes e representadas por juvenis: Micropogonias furnieri, Mugil platanus, Paralichthys orbignyanus e Brevoortia aurea. A comunidade variou sazonalmente com rápidas mudanças na primavera e no outono, associadas à variações de temperatura e salinidade. Correlações significativas entre abundância e temperatura parecem estar relacionadas com a sincronizaçao de eventos dos ciclos de vida. Neste estuário a salinidade parece desempenhar um papel-chave na estrutura funcional e uso do habitat por juvenis. Este fato é relevante para a definição dos estuários como áreas de criadouro e pela influencia da salinidade sobre o ciclo da ictiofauna local.

“…Ao mesmo tempo a própria pesca do camarão sete-barbas também pode trazer prejuízos ao meio ambiente, seja pelo impacto das redes de arrasto sobre o fundo (TURNER et al, 1999) ou pela mortalidade de juvenis de peixes e crustáceos de valor comercial ou importantes para a biodiversidade marinha através do descarte (LAZZARI et al, 2003), como reportado em diversos estudos na costa brasileira tais como SANTOS et al (1998); TISCHER e SANTOS (2001); BRANCO e VERANI (2006); PINHEIRO e MARTINS et al (2009)…”

RESUMOO tamanho de primeira maturação, ciclo reprodutivo e razão sexual do camarão sete-barbas Xiphopenaeus kroyeri foram estudados a partir de amostras mensais em duas áreas litorâneas do Estado do Espírito Santo, entre 2003 e 2004, visando subsidiar futuras medidas de manejo. As coletas foram feitas com redes de arrasto de fundo em pequenos barcos de pesca artesanais , entre 4 e 8 m de profundidade. Foram capturados 6.006 exemplares sendo 2.766 fêmeas, 3.182 machos e 58 de sexo indeterminado. As fêmeas foram significativamente maiores do que os machos. O comprimento médio de primeira maturação gonadal das fêmeas foi de 9,026 cm. As fêmeas adultas foram mais numerosas do que os machos entre dezembro e fevereiro, coincidindo com o pico de desova, enquanto que os machos adultos predominaram no trimestre subsequente. Essa alternância de proporções foi associada a migrações batimétricas reprodutivas das fêmeas. O ciclo anual de maturação gonadal, a abundância sazonal, variação dos tamanhos médios e a presença sazonal de juvenis sugerem a existência de desova contínua e recrutamento de dezembro a fevereiro e em julho e agosto. As dificuldades de se estabelecer um período de defeso adequado no estado indicam que o manejo do recurso deva receber maior atenção devido aos aspectos envolvidos, sejam sociais, biológicos ou ambientais.Palavras chave: Xiphopenaeus kroyeri; reprodução; recrutamento; defeso; razão sexual; pesca artesanal BIOLOGY OF THE SEA-BOB SHRIMP FROM THE ESPÍRITO SANTO COAST, BRASIL ABSTRACTThe size at first maturity, reproductive cycle, sex ratio and recruitment of the sea-bob shrimp Xiphopenaeus kroyeri were studied from monthly samples in two coastal areas of the Espírito Santo state between 2003 and 2004 in order to support sustainable management of this species. The samples were obtained with bottom trawls in small artisanal fishing boats from 4 to 8 m deep. A total of 6,006 specimens were captured being 2,766 females, 3,182 males and 58 of undetermined sex. Females were significantly bigger than males. The average length of first maturation of females was 9.026 cm. Adult females predominated over males between December and February, coinciding with the spawning peak, while males predominated in the subsequent quarter. This alternation of proportions was associated with bathymetric migrations of reproductive females. The annual gonadal maturation cycle, seasonal abundance and sizes and recruits suggest the existence of continuous spawning and recruitment in December-February and in July and August. The difficulties of establishing a closed season in proper condition indicated that the management of the resource should receive more attention because of the issues involved, whether social, biological or environmental.
