“…The meat yield of the banded murex from the Ria Formosa (37.9 + 4.6%) compared favourably with similar data reported for H. trunculus from other geographical areas, such as 33.3% in Cyprus (Alyakrinskaya, 2004(Alyakrinskaya, , 2005, 33.6% in Slovenia (Dalla Via & Tappeiner, 1981) and 34.2% in Greece (Alyakrinskaya, 2004(Alyakrinskaya, , 2005 (all data converted from percentage of shell weight/total weight). The comparison of meat yield between species is rather complicated due to the different types of meat extraction (mechanized versus manual), treatments (raw versus cooked, wet weight versus dry weight) and organs/tissues included in the edible content (foot, mantle, digestive gland, gonads, etc.).…”

This study aimed to assess the influence of growth and reproductive cycle on the meat yield and proximate composition of the banded murex (Hexaplex trunculus) from the Ria Formosa lagoon (Algarve coast, southern Portugal). Samples of the edible portion (all soft-body tissues) were analysed monthly during one year. The average meat yield was 37.9 + 4.6%, with females containing more edible content (39.1 + 4.7%) than males (36.8 + 4.2%). The proximate composition comprised 70.7 + 1.4% moisture, 20.1 + 1.2% protein, 1.6 + 0.3% fat, 3.0 + 0.3% ash, and 4.6 + 1.2% carbohydrate, corresponding to an energetic value of 119.2 + 7.5 kcal/100 g wet weight. The meat yield was influenced by specimen size, increasing significantly during growth. Both meat yield and proximate composition presented seasonal fluctuations related to the reproductive cycle, which coincided mainly with the periods of maturation and spawning of this species in the Ria Formosa. Finally, H. trunculus meat yield and proximate composition were compared with similar information available for other marine gastropods.

“…Chicoreus ramosus and Fasciolaria trapezium). Only Bolinus brandaris, another muricid species whose edible content also includes all soft-body tissues, presented higher meat yield (42.5%), which is explained by the fact that B. brandaris has a weaker, thinner and 10% lighter shell than H. trunculus (Dalla Via & Tappeiner, 1981).…”

“…Both species have extended their distribution areas, possibly due to accidental introduction of juveniles among bivalves imported for shellfish culture (Vasconcelos et al, 2016). The purple dye murex (Bolinus brandaris) generally occurs in the sublittoral zone (Dalla Via and Tappeiner, 1981) although the occurring was reported at 200 m (Macedo et al, 1999). The species prefers sandy, muddy, and sandy-muddy habitats (Muzavor and Morenito, 1999).…”

“…The species prefers sandy, muddy, and sandy-muddy habitats (Muzavor and Morenito, 1999). The banded murex (Hexaplex trunculus) usually occurs between intertidal and infralittoral zones until the depth of 200 m (Dalla Via and Tappeiner, 1981;Macedo et al, 1999). Houart (2001) reported that this species is frequently occurring between the depths of 0.3 m and 30 m. The banded murex prefers both soft and hard habitats such as sandy, muddy, rocky, and sandy-muddy substrates (Macedo et al, 1999;Muzavor and Morenito, 1999;Houart, 2001).…”

Small-scale fisheries have a high socioeconomic importance for local communities. Therefore, ensuring the sustainability of fisheries resources would contribute to the socioeconomic development of fisheries communities. In this study, traps produced from plastic waste recycle materials which can be used in fishing of economically valued whelks (Hexaplex trunculus and Bolinus brandaris) that are used as natural bait in angling and longline fishing were investigated. These traps in different sizes were examined at the depths of 3-8 m in the Urla coasts of Izmir Bay, Turkey. The soaking times of traps were between 10-48 hours. The same amounts of baits (Sardina pilchardus) were equally placed in all traps. Catch per unit efforts (CPUE) of traps were calculated between 7-34 individuals/trap per day. The experimented traps were found successful for whelks fishing. Traps yield high quality and economically valued catches, related to restricted bycatch and low impact on habitat. Therefore, these traps can be suggested as alternative fishing gears designed for trap fisheries for whelks. This paper provides valuable knowledge for fisheries managers and decision makers to ensure the sustainability of local fisheries resources and small-scale fisheries.

“…Nowadays, B. branda-ris also occurs in some areas of Galicia (NW Spain), probably as a consequence of accidental introduction of juveniles together with bivalves imported for culture (Bañón et al 2008). This species generally occurs in the sub-littoral (Dalla Via and Tappeiner 1981), but can also be found at 100-200 m depth (Macedo et al 1999, Muzavor andMorenito 1999), inhabiting sandy, sandy-muddy or muddy bottoms (Macedo et al 1999, Muzavor and Morenito 1999, Anon. 2001.…”

SUMMARY: The present study reports the growth rate of the purple dye murex, Bolinus brandaris (Gastropoda: Muricidae), estimated from mark-recapture experiments. A total of 1067 specimens (shell length = 43.4±8.1 mm, range = 14.6−78.4 mm) were marked with Dymo ® tape tags and released in a semi-intensive fish culture earthen pond. After a period at liberty ranging from almost two months to around two years, 288 individuals were recaptured (shell length = 67.4±6.2 mm, range = 45.3−88.6 mm), which corresponded to a recapture rate of 27.0%. At recapture, only one specimen had lost the tag (tag loss rate <0.1%) and all remaining tags were intact and legible. Mean monthly growth rates were 0.9±1.0 mm in shell length, 0.4±0.5 mm in shell width and 0.7±0.7 g in total weight. Growth rates showed high inter-individual variability and an evident decreasing trend with specimen size. Comparison of growth rates with similar information available for other muricids confirmed that B. brandaris is a relatively slow-growing species. This provides valuable information for both fisheries management and for assessing the potential of B. brandaris as a candidate species for molluscan aquaculture.Keywords: purple dye murex, Bolinus brandaris, Gastropoda, Muricidae, mark-recapture, growth rate. RESUMEN: Crecimiento de la cañailla, Bolinus Brandaris (Gastropoda: Muricidae), mediante técnicas de marcado-recaptura realizadas en estanques de cultivo semiintensivo de peces. -Se ha estudiado el crecimiento de la cañailla Bolinus brandaris (Gastropoda: Muricidae) mediante técnicas de marcado-recaptura. Se marcaron un total de 1067 individuos (longitud concha = 43.4±8.1 mm, rango = 14.6−78.4 mm) con etiquetas plásticas Dymo, que fueron puestos en libertad en un estanque en tierra dedicado al cultivo semiintensivo de peces. En el plazo de tiempo comprendido entre dos meses y dos años, se recuperaron 288 ejemplares (longitud concha = 67.4±6.2 mm, rango = 45.3−88.6 mm), lo que corresponde a una tasa de recaptura del 27.0%. Las etiquetas permanecieron intactas y legibles en todos los ejemplares recuperados, a excepción de un único individuo (tasa de pérdida de marca <0.1%). La tasa de crecimiento media mensual estimada fue de 0.9±1.0 mm de longitud, 0.4±0.5 mm de anchura y 0.7±0.7 g de peso total. Esta tasa muestra una elevada variabilidad intraespecífica y una tendencia clara a la disminución con el aumento de la talla. Comparando las tasas de crecimiento obtenidas en este estudio con la información disponible sobre diversas especies de murícidos, se confirma que B. brandaris es un gasterópodo de crecimiento relativamente lento. Este estudio resulta de interés tanto para gestionar la pesca de este recurso como para evaluar el potencial de la especie como candidata a ser cultivada.
