“…Lombarte et al, (2000), who studied the spatial segregation of M. barbatus and M. surmuletus in the western Mediterranean, have also reported that M. barbatus shows a clear preference for the areas where the shelf becomes wider, while M. surmuletus prefers narrow shelf areas with rocky or sandy bottoms. In addition, ecomorphological studies suggest the existence of adaptive morphological and anatomical characteristics that allow M. barbatus to exploit better than its congeneric species resources from muddy and turbid bottoms (Lombarte and Aguirre, 1997).…”

SUMMARY: The present work attempts to study the spatio-temporal distribution of Mullus barbatus and M. surmuletus in the Mediterranean Sea by using a time series of data from an international bottom trawl survey that covered a wide area of the Mediterranean Sea. The experimental surveys were accomplished annually from 1994 to 2000 on approximately 1000 pre-defined sampling stations distributed in 15 major areas. Selection of stations was based on a depth-stratified random sampling scheme that included five depth strata: 10-50, 50-100, 100-200, 200-500 and 500-800 m. The examined species were found throughout the studied region, mostly in depths down to 200 m. Abundance differences among major areas were found to be statistically significant and were attributed to the different exploitation patterns, as well as the different abiotic and biotic conditions prevailing in each area. Although both species undergo high fishing pressure, results did not demonstrate any decreasing trends in their abundance indices suggesting the existence of a good stock-recruitment relationship over the studied period. However, the dominance of young fish that has been found, makes the stocks highly vulnerable to recruitment changes; hence protection of spawning and nursery areas seems to be essential for their conservation.

“…They show common morphological characteristics that differentiate them from other genera of Mullidae, including the arrangement of the teeth (Hureau 1986, Aguirre 1997) and the cephalic musculature and skeleton that determine the head profile characteristic of the genus Mullus (Gosline 1984). They also have common behavioural features, especially relative to feeding, since both species are benthic carnivores.…”

“…Barbels have been found to vary considerably in structure, size, and sensory equipment (e.g. Gosline 1984;Uiblein et al 1998;Lombarte & Aguirre 1997). However, many other morphological traits of goatfishes, such as body size, coloration, head form, otolith form, or the number of countable characters, such as gillrakers, fin rays, or vertebrae, may vary interspecifically (e.g.…”

Goatfishes (Mullidae) as indicators in tropical and temperate coastal habitat monitoring and management

This review investigates if goatfishes qualify as habitat indicators and play a role as key species for use in coastal ecosystem monitoring and management, emphasizing major gaps of knowledge in goatfish ecology and systematics. Currently, 66 species of goatfishes are known, the family occurring widely in tropical, subtropical and temperate habitats from the upper littoral down to the upper slope. Studies of goatfish occurrence and abundance in natural habitats have documented general preferences for sand-associated bottoms after post-larval settlement that goes hand in hand with the development of the characteristic barbels. Species, populations and later life-history stages may, however, differ significantly from each other in habitat use. Some species are more restricted to hard bottoms, others separate mainly by depth. Goatfishes respond to human-induced factors such as fisheries and habitat modification, as reflected by abundance, size, or weight changes, or changes in their distributional ranges. Temperature increase may lead to increased reproductive or growth rates and longer warming periods may induce goatfishes to migrate to higher latitudes, as exemplified by striped red mullet (Mullus surmuletus) in the North Sea. Isolated occurrences of this species in the Norwegian Sea at 608N have been documented. Goatfishes may act as allochthonous ecosystem engineers through their vigorous foraging behaviour with barbels and mouth, which leads to the stirring-up of sediments and associated detritus particles high into the water column. Goatfishes play a key role in the formation of multi-species foraging associations as nuclear species that are followed by many other species. The role of goatfishes in food webs has been rarely evaluated and the many interactions goatfishes may be involved in have not yet been sufficiently considered. There is also a considerable lack of basic systematic and taxonomic knowledge, new species still being described and intraspecific morphological variation and genetic differentiation requiring more detailed studies. Goatfishes clearly deserve more attention in future coastal habitat exploration, monitoring and management efforts.
