“…These factors can explain the differences in L 50 observed between the Mediterranean and Atlantic populations. In fact, L 50 appears to always be greater for the Atlantic populations than the Mediterranean populations: 56.2 cm TL in Portuguese waters (Azevedo, 1996), 53.0 cm TL in Atlantic Iberian waters (Duarte et al, 2001;Landa et al, 2014), 58.7 cm TL in the Bay of Biscay (Quincoces, 2002), and 70.4 cm TL in Scottish waters (Laurenson et al, 2008). Considering the Mediterranean Sea, Tsimenidis (1984) estimated an L 50 at 34.0 cm T in females and 24.0 cm TL in males of L. budegassa in the Aegean Sea, while Colmenero et al (2013) found 48.2 cm TL for females and 33.0 cm TL for males in the north-western Mediterranean.…”

“…In general, its contribution in terms of the volume of landings is low, except in some areas such as the Gulf of Lions and the Catalan Sea (Ungaro et al, 2002;Colmenero et al, 2013). In the European Atlantic waters, the blackbellied angler investigations have included estimation of growth parameters (Dupouy et al, 1986;Duarte et al, 1997;Landa et al, 2001Landa et al, , 2008Landa et al, , 2014Quincoces, 2002); characterisation of reproduction (Azevedo, 1996;Duarte et al, 2001;Quincoces, 2002) and diet (Crozier, 1985); and evaluation of spatial distribution (Azevedo et al, 2008, Barcala et al, 2019. However, despite the ecological and economic relevance of the blackbellied angler, in the Mediterranean Mediterranean Marine Science Indexed in WoS (Web of Science, ISI Thomson) and SCOPUS The journal is available on line at http://www.medit-mar-sc.net www.hcmr.gr DOI: http://doi.org/10.12681/mms.36320…”

In the Mediterranean Sea, the blackbellied angler, Lophius budegassa Spinola, 1807, represents a relevant fraction of the commercial by-catch of bottom trawling and small-scale fisheries that use passive gears (e.g., set nets, bottom longlines, etc.). Despite its importance, there are no comprehensive studies on the population dynamics of this species, and there is still scarce and scattered knowledge of its biology and ecology. Biomass, morphometric, and biological data of the blackbellied angler were collected from 1994 to 2021 by means of the Mediterranean International Bottom Trawl Survey (MEDITS) programme in the Ligurian and northern Tyrrhenian Seas, and in the EU Data Collection Framework during the period of 2006-2021. Furthermore, ageing was performed on specimens collected from 2013 to 2021 during the MEDITS programme. There were high values for the density indices and the spatial distribution of biomass in the central sector of the investigated area (the Tuscan Archipelago), mostly on the continental shelf. The length-weight relationship showed negative allometric growth when considering the sexes together, and no difference between the sexes. The size at first maturity (L50) was estimated at 39.4 cm total length (TL) in females and at 29.2 cm TL in males. The obtained Von Bertalanffy growth parameters were: in females, L∞ = 74.50 cm, k = 0.10 years-1, and t0 = -0.40 years; in males, L∞ = 61.30 cm, k = 0.14 years-1, and t0 = -0.38 years. There were differences in growth between males and females for L∞ (χ2 = 10.04; p < 0.05) and k (χ2 = 6.12; p < 0.05).

The aim of this study was to provide a first approximation of the growth, reproduction, and length–weight relationships of Symphodus ocellatus in the southeastern Black Sea, Turkey. A total of 320 specimens (273 males, 47 females) were collected between June 2015 and May 2016, and their biological parameters were estimated for each sex and both sexes combined. Total length ranged from 6.90 to 13.70 cm and the parameters (a, b) in the power length–weight relationships were a = 0.065 and b = 2.38 for males and a = 0.102 and b = 2.20 for females. Age was successfully estimated by commonly accepted procedures for otolith analysis. The von Bertalanffy growth parameters from the otolith age estimation were L∞ = 12.66 cm, k = 0.764, and t0 = –1.151 (0–3 years) for males, and L∞ = 14.15 cm, k = 0.764, and t0 = –0.188 (1–3 years) for females. The monthly gonadosomatic index values reflected a spawning period between April and July, with a spawning peak in May–June. The present study provides the first estimate of the growth and reproduction of S. ocellatus in the southeastern Black Sea of Turkey and compares the results with those from other areas.
