“…Spawning of Scorpaena porcus in captivity showed the spawn floats on the surface, and hatching began 56 hours after fertilization (range 53 hours to 59 hours) at 20⁰C water temperature. By the time hatching began, the gelatinous matrix around the eggs had dissolved and disappeared (Szabolcs et al, 2010).…”

Reproductive mode in Helicolenus dactylopterus has been debated since around 1900, and to our knowledge, no previous report on free floating egg mass of H. dactylopterus. Some authors claim viviparous strategy, others oviparous, or also that the species display a zygoparous or embryoparous form of oviparity. The most recent publications (ovarian studies) claim H. dactylopterus «definitely appears to be zygoparous», and due to «release of developing zygotes in the early phases of development», is zygoparous.We report on the first free floating, gelatinous egg mass matrix of Helicolenus dactylopterus, observed in situ. It was observed from Haganes pier, Bergen, Norway 10 April 2020, at 20 cm depth. Live eggs were mostly of the same size (~1 mm), and at late blastula stage. Pictures of live eggs from within the «Haganes matrix» is provided. Ethanol preserved eggs were obtained for DNA barcoding, employing sequences from the cytochrome c oxidase subunit I gene (COI). COI showed 100% similarity with sequences of adult blackbelly rosefish, H. dactylopterus. The species is previously known for internal fertilization, and the in situ observation of the Haganes matrix, with embryos at late blastula stage, is confirming theories of a zygoparous strategy.

One of the most important aspects of the marine environment study is the investigation of the diversity of parasites, especially in marine fishes (Sasal et al., 1997). Parasites are commonly used as biological tags in fish population studies, and especially for discriminating between fish stocks in fisheries studies (Catalano et al., 2014;Mackenzie, 1983;Poulin & Kamiya, 2015). The important factors that affect the viability of natural populations and communities are infestation with parasites and parasitic diseases (Combes, 1995;Morand & Arias Gonzalez, 1997), given that marine fish individuals may suffer from parasitic attacks (Faliex & Morand, 1994).The black scorpionfish (Scorpaena porcus L., 1758) is a marine demersal non-migratory fish species inhabiting the waters of the Eastern Atlantic from the British Isles in the north to the Canary Islands in the south including the Mediterranean and Black Seas (Hureau & Litvinenko, 1986). The fish is known as a commercial fisheries species in the Mediterranean basin, also a prospective aquaculture species (Németh et al., 2010). Instead of this, the black scorpionfish is known as a traumatogenic fish species, which is dangerous for human health (Halstead et al., 1990).According to the published data, in the past, the black scorpionfish was sporadic in the whole North-Western Black Sea (NWBS) including the Odessa region (Movchan, 2011;Zambriborshch et al., 1995). This Atlanto-Mediterranean fish species avoid the desalinated and cold parts of the sea. In the Gulf of Odessa, this fish was a common component in the historical period (Vinogradov, 1960) but almost disappeared in the 1980 -1990s (Zambriborshch et al., 1995. In recent several decades, the black scorpionfish increased in number in the Gulf of Odessa (Khutornoy, 2000;Zamorov et al., 2019). In 2005-2010, the density of this fish in the Gulf of Odessa, by the data of net catches, was recorded as sporadic (Chernykova & Zamorov, 2011). But it started to be a common species in the
