“…Solea solea maintained a similar production throughout the study period and similar values to other systems elsewhere (0.02 for the Irish Sea, Costa et al, 2002, and 0.24 g WW m À2 y À1 for Osterschelde estuary, Hostens and Hamerlynck, 1994). Pomatoschistus minutus showed a considerable decrease in production in the drought year of 2005 contrarily to P. microps, which is more tolerant to higher temperatures (Fonds and Buurt, 1974). More details and comparisons of both Pomatoschistus spp.…”

“…Accordingly, the production showed a clear decrease during the dry year of 2005, with the highest decreases observed for Dicentrarchus labrax, Platichthys flesus and Pomatoschistus minutus. It is difficult to ascertain the main factors for this decrease (in agreement to the ''Estuarine Quality Paradox'', Elliott and Quintino, 2007), yet experimental studies have revealed the limiting effect of high temperatures and salinity variations on eggs and larval development of P. minutus and Pomatoschistus microps (Fonds and Buurt, 1974) and of P. flesus . Solea solea seems more tolerant to variations in temperature and salinity (Fonds, 1975).…”

The production of resident (Pomatoschistus minutus and Pomatoschistus microps) and marine juvenile fish species using the Mondego estuary (central Portugal) as nursery grounds (Dicentrarchus labrax, Platichthys flesus, Solea solea), was assessed in order to: (1) understand the potential of the estuary for fish production; (2) know the production of nursery fish species likely to be exported to the coastal stocks; and (3) how anthropogenic and natural stress could influence the estimated production. C, night temperatures). The secondary production was estimated using the increment summation method, after recognition of the cohorts. Production was in general lower in the Mondego estuary when compared to other systems, which was associated to the estuary's small area (only 3.4 km 2 , less than 1/4 of area compared to other studied systems). Dicentrarchus labrax was among the most productive species. Production decreased in the drought year for all species, especially evident for D. labrax, P. minutus and P. flesus. No direct effects could be attributable to the salinity and temperature variations and to the low freshwater discharges (resulting from the drought and high temperatures), yet these were pointed as probable major reasons for the decreased production. A significant reduction (15e45% reduction in the estuarine production) was also concluded for the potential production to be exported for coastal areas by the nursery species in the drought conditions.

“…Furthermore, eggs of the common goby survived well in a wider salinity range (5 to 35%0), than those of the sand goby (15 to 35%0). In Kvambukten Bay the sand goby bred 1 mo earlier than the common goby (Evans & Tallmark 1984), which also supports the results of Fonds & van Buurt (1974). In Gullmar Fjord a slight temporal and spatial segregation of the 2 gobiids may thus occur which should reduce competition for suitable nestsites.…”

“…The eggs of the sand goby, on the other hand, occurred both close inshore and in deeper water (Fonds 1973, Hesthagen 1977 Evans & Tallmark 1979). According to experimental findings by Fonds & van Buurt (1974), temperature and salinity boundaries for the development of gobiid eggs will influence gobiid distribution. Eggs of the common goby survived within a narrow temperature range (15 to 20 "C), compared to the eggs of the sand goby (10 to 20 "C).…”

Segregation of coexisting predatory fish and shrimp species on marine shallow soft bottoms was studied in the Gullmar Fjord (Sweden). Here, the gobiids Pomatoschistus minutus (Pallas) and P. microps (Krayer) and the brown shrimp Crangon crangon L. are the most abundant epibenthic species close inshore. A temporary reduction in number of one of the species was balanced by an increased recruitment of other species in the guild, so that the overall density of epibenthic predators was kept at approximately the same level. Experimental validation of field results showed that segregation maintained by interspecific territoriality is an important mechanism regulating guild structure. We argue that competitive relations undoubtedly are of importance in maintaining structure of the epibenthic communities in Gullmar Fjord, but of minor importance for overall density of the guild.

“…The common goby is sympatric with the sand goby P. minutus in several estuaries, and presents some degree of habitat and diet overlap (Leitão et al 2006;Złoch and Sapota 2010). Nevertheless, the sand goby is less tolerant to salinity and temperature fluctuations than the common goby, preferring to inhabit estuarine zones with higher salinities or the sea, whereas P. microps is preferentially found in brackish waters (Fonds and Van Buurt 1974;Pampoulie et al 1999). In the Minho estuary, during winter, salinity can reach extremely low values even near the river mouth.…”

Structure, growth and production of a remarkably abundant population of the common goby, Pomatoschistus microps (Actinopterygii: Gobiidae)

The common goby, Pomatoschistus microps, is a relevant species from estuarine food webs, playing important roles as predator of polychaetes and crustaceans and as prey for larger fishes and crustaceans. The Minho estuary (NW Portugal) is a relatively wellpreserved and productive system. To assess the population structure and production of P. microps in this estuary, monthly samples were undertaken in three different areas along an estuarine gradient in the lower estuary. The density of P. microps varied considerably among seasons and sampling stations, with higher densities occurring in summer and autumn. The lowest densities were found closer to the sea. In general, the density of females was higher than the density of males in all sampling stations, while juveniles were more abundant within a salt marsh area. Compared with other European estuaries, our data showed a remarkable higher density and production values of P. microps. This may be related to the high freshwater input and the low salinities found in this estuary. In addition, we hypothesize that the lower density of the sympatric species P. minutus and the high availability of bivalve shells observed in the Minho estuary may have also contributed to the present results, once P. minutus and P. microps often display a diet overlap and the bivalve shells are crucial for the common goby reproduction.
