“…The pouting, Trisopterus luscus (Linnaeus, 1758), is a species with a wide distribution across Atlantic waters, occurring from Skagerrak and the British Isles to southern Morocco and the western Mediterranean, preferably in rocky and sandy areas on the continental shelf at depths of 30 -100 m (Wheeler, 1978;Whitehead et al, 1986). Pouting on the Galician shelf has a protracted spawning season, spanning from mid-winter to early spring with a spawning peak between February and April (Alonso-Fernández et al, 2008), which is in agreement with studies conducted on ichthyoplankton in those same waters (Ferreiro & Labarta, 1988). This teleost of the Gadoid family is of major commercial importance for the artisanal fleet of a number of European countries, but especially for France, Portugal and Spain.…”

“…Studies on eggs and larvae of this species are scarce (Ferreiro & Labarta, 1988;Fox et al, 1997). Despite some existing literature concerning the developmental biology of this species, the description of its embryonic development remains incomplete (Ehrenbaum, 1905(Ehrenbaum, -1909D'Ancona, 1933) and all the data regarding incubation times and embryonic development are exclusively from Erhenbaum (1905 -1909).…”

Embryonic development and spawning pattern of Trisopterus luscus (Teleostei: Gadidae) under controlled conditions

Knowledge on early ontogeny of Trisopterus luscus is scarce and incomplete. This paper describes the first successful attempt ever at achieving the natural spawning in captivity for this species. The reproductive specimens used for this study were obtained in the Ría de Vigo in September 2008 and subsequently transported to the facilities of the Institute of Marine Research (CSIC). The spawning frequency was variable among females, 1.8–4.6 days, but no size-dependent trend was determined. The average batch size, i.e. the number of eggs released per batch, has proven significantly dependent on female length and weight. In the present study the complete embryonic development in controlled conditions (sand–filtered seawater at ~13°C, with natural photoperiod), from egg to hatched larva, has been described for the first time ever. The development of pouting eggs was divided into six stages, based on the artificially-reared material. Pouting eggs are pelagic with a smooth, clear and spherical chorion, and a homogeneous yolk. The perivitelline space is narrow and oil globules are absent. Live eggs fertilized were 0.95–1.10 mm in diameter. The embryo hatches as a yolk-sac larva with closed mouth and gut. The pouting eggs hatched during the latter half of the fifth day.

“…In general, the community structure and distributional patterns found in this study can be compared with other studies in the Iberia North western coastal area: Portugal northwestern coast (Andres et al, 1992), central western coast (Ré et al, 1982), and Galician Rias and coastal zone (Lopez-Jamar, 1977;Ferreiro and Labarta, 1988). However, this study was conducted in a very specific area: very near to the coast (near to shore shallow area before the surf zone in the direction of the shoreline), associated with unique biological and ecological features (Harris et al, 1999;Hernández-Miranda et al, 2003).…”

Monthly sampling for ichthyoplankton was conducted at three stations very near to the coast (near to shore shallow stations before the surf zone in direction to the shoreline) of Atlantic northwestern Portugal within contrasting localities: rocky shore, in front of a sandy beach receiving an estuary and a fishing port with heavy anthropogenic impact. Sampling was conducted from August 2002 to October 2003, always at full moon, at low tide and high tide in daylight hours, at the water column using a 48 cm diameter plankton net with 335 mm mesh. Analysis of the physico-chemical parameters pointed out the spatial (horizontal) homogeneity of the sampling area. Fish larvae from 41 taxa belonging to 17 families were identified; Blenniidae, Labridae, Ammodytidae, Clupeidae, Gobiidae, Soleidae and Gobiesocidae were the most representative during the study period. Parablennius gattorugine, Ammodytes tobianus, Symphodus melops, Sardina pilchardus, Lipophrys pholis and Coryphoblennius galerita were the most representative species (percentage contribution to total abundance). Peak abundance of fish eggs occurred during May, June and August 2003 and fish larvae occurred during May and July 2003 and August 2002; there was a pronounced winter/early spring (March 2003) peak in larval abundance dominated by the small sandeel A. tobianus. This study identifies the occurrence of a conspicuous assemblage of larval fishes at very nearshore shallow environments of a variety of species with different adult habitats: the fish larvae assemblage was dominated by intertidal species. The present study has shown that temporal and spatial variations in the larval fish assemblage are related to environmental conditions and biological dynamics: the results suggest that abiotic conditions mediate biotic parameters, and that both abiotic and biotic characteristics regulated the larval fishes at very nearshore shallow environments.

“…In nearby regions, studies of the LFC are also scarce (John & Re 1995, Rodriguez 2008, Garrido et al 2009, Rodriguez et al 2011, and none was carried out during the winter mixing period. Other studies were restricted to very littoral regions (Azeiteiro et al 2006) or were carried out in the Galician rias (LopezJamar 1977, Ferreiro & Labarta 1988. Thus, ours is the first study of the LFC carried out in this region during the winter mixing period.…”

The composition and structure of the larval fish community (LFC) in the NW Iberian upwelling system in late winter 2012 were examined, and the influence of abiotic and biotic factors on the horizontal distribution of fish larvae and on the horizontal structure of the LFC was investigated. The LFC, composed of 62 taxa (59 species and 3 genera) in 28 families, was dominated by Micromesistius poutassou followed by Scomber scombrus, Merluccius merluccius and Maurolicus muelleri. Multivariate analyses identified depth, sea surface temperature, geostrophic velocity and mesozooplankton biomass as the environmental factors involved in explaining variability in the LFC parameters (larval fish abundance, species richness and diversity) and revealed that the LFC was structured into coastal and slope larval fish assemblages. The main factor defining these assemblages was depth. However, the unusual coastal downwelling that occurred during the study would have participated in creating them and in maintaining assemblage boundaries, so that the importance of depth to the cross-shelf structuring of the LFC may have been overestimated. Our results suggest that larval fish assemblages in regions of coastal upwelling are driven by coastal downwelling during the winter mixing period and support the idea that fish larvae act as short-term (~10 d) biological tracers of the hydrography of the region during that period.
