Assessment of the relative catch performance of hake, red mullet and striped red mullet in a modified trawl extension with T90 netting

Scientia Marina, 2018
We studied the relative catch performance of a modified trawl fitted with an extension piece using a 90º turned mesh (T90) in comparison with a standard trawl net used in NW Mediterranean bottom trawl fisheries employing a diamond mesh net.

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

Incidence and significance of cystic structures in the ovaries of gadoid fish

Scientia Marina, 2011
Fish regulate egg production by atresia. Sometimes, oocytes are encapsulated in cystic structures that might remain in the ovary for months, altering female reproductive potential in future spawning seasons.

Bioeconomic simulation analysis of hake and red mullet fishery in the Gulf of Saronikos (Greece)

Scientia Marina, 2007
Hake (Merluccius merluccius) and red mullet (Mullus barbatus) are two of the most important species in Greek fisheries due to their high commercial interest. Both have been reported to be overexploited and in need of management to preserve the continuity
