First detection of the non-indigenous gastropod Rapana venosa in the southernmost coast of Brazil

Incorporation of Rapa Whelk (Rapana venosa) meal in diets for rainbow trout (Oncorhynchus mykiss) fry

“…Concerning the invasive features of R. venosa, the European Union Parliament reported its negative effects on the blue mussel ( Mytilus galloprovincialis ) and the striped venus ( Chamelea gallina ) populations that the precautionary solutions must be taken in response to predation pressure, which poses a significant threat to the ecological balance (Anonymous, 2011). Other studies also indicate several serious adverse effects of R. venosa on green sea turtle Chelonia mydas (Lezama et al., 2013; Spotorno‐Oliveira et al., 2020) or bivalve species such as Mactra isabelleana, Ostrea puelchana (Spotorno‐Oliveira et al., 2020), Ostrea edulis and Flexopecten glaber (Chukhchin, 1961; Drapkin, 1963). Bringing in the snails that are discarded by processing facilities could have a positive economic impact; moreover, the invasive nature of the species also supports the idea that this animal can be used in fish feeds instead of fishmeal (Sahin et al., 2018).…”

“…Rapana venosa , the veined Rapa whelk, is a prominent member of the Muricidae, known as the family of predatory marine snails (Kerckhof et al., 2006), and is one of the marine organisms that has the potential to replace fishmeal due to its high protein content and desirable amino acid profile (Sahin et al., 2018). Although R. venosa is native from the Japanese Sea, Yellow Sea, Bohai and East China Seas to Taiwan (Savini & Occhipinti‐Ambrogi, 2006), its known reproducing populations are established along the Black Sea, Adriatic, Marmara, Aegean Seas, coasts of Brittany, the Netherlands, Chesapeake Bay, La Plata River estuary in Argentina–Uruguay and southern Brazil in time (ICES, 2004; Spotorno‐Oliveira et al., 2020). Concerning the invasive features of R. venosa, the European Union Parliament reported its negative effects on the blue mussel ( Mytilus galloprovincialis ) and the striped venus ( Chamelea gallina ) populations that the precautionary solutions must be taken in response to predation pressure, which poses a significant threat to the ecological balance (Anonymous, 2011).…”

Effects of Rapana venosa meal‐supplemented diets on reproduction, histopathology and some blood parameters of rainbow trout ( Oncorhynchus mykiss ) broodstock

“…Rapana venosa (whelk) is one of the predatory marine snail species that belong to the Muricidae family (Kerckhof et al, 2006) and is native to East Asia waters (Savini & Occhipinti‐Ambrogi, 2006). Nonetheless, its presence in the world waters extended due to its invasive nature, and it established along many seas from the Black Sea to the La Plata River estuary in Argentina–Uruguay and southern Brazil in time (ICES, 2004; Spotorno‐Oliveira et al, 2020). Although there is plenty of information about the suppressive effects of whelk on populations of various economic bivalve species (Berndt et al, 2014; Lezama et al, 2013; Savini et al, 2004; Savini & Occhipinti‐Ambrogi, 2006), its economic value for human consumption in Asian countries (Janssen et al, 2014) makes it significant.…”

Microwave Technology Using Low Energy Concentrated Beam for Processing of Solid Waste Materials from Rapana thomasiana Seashells

“…In 1942 it was first recorded in the Black Sea. In a very short time, it spread along the Caucasus coasts, the Sea of Azov [39,40], the Marmara Sea, the Aegean Sea, the Adriatic Sea, the Mediterranean Sea, the United States (east coast) [41] and Brazil (south coast) [42]. RT fishing mainly uses the dredging method, in addition to methods such as scuba diving.…”
