Serranus hepatus is a bycatch species in the Mediterranean trawl fishery for which knowledge on biological features such as otolith morphology is generally poor in the Mediterranean Sea. In the present study, the weight–length relationship, age, growth and ten otolith morphometric variables of this species were investigated in two distant areas, the Eastern Ionian and southwestern Aegean Seas. Isometric growth in weight was defined in both areas. Growth parameters also did not differ between the two study areas. Six of the otolith variables (radius, otolith length, otolith width, otolith area, perimeter and ellipticity) showed a significant relationship with size without significant differences between the two areas. Significant differences between the two areas were only defined for five of the morphometric variables (otolith length, width and area being the most important). Further studies to discriminate between potential stocks of S. hepatus seem to be necessary, information that is needed for stock identification, stock assessment and fisheries management.

“…DFO [22] identified an unknown number (described as "many") of the 48 predated smolt based on the occurrence of otoliths in stomach contents of the striped bass. Identifying fish species in diets using otoliths is possible [76], but it can be complicated as otoliths are subject to erosion in the gut [77,78]. Identifying otoliths in diet studies requires protocols that include reference collections and/or atlases to address otolith erosion and double counting [77,79].…”

The native striped bass (Morone saxatilis) population of the Miramichi River, New Brunswick is undergoing an unprecedented recovery while Atlantic salmon (Salmo salar) numbers within that system continue to decline. Atlantic salmon smolt depart from the Miramichi system during the striped bass spawning period and it is hypothesized that elevated striped bass abundances will increase encounter rates and predation on smolts. We summarize all available striped bass diet studies occurring within the native range of Atlantic salmon and present a review of the feeding behavior and diet preferences of striped bass before, during, and after their spawning period. The key studies vary in methodologies and interpretability. We present a standardized approach for assessing striped bass predation threats and smolt vulnerability and thus an improved understanding of the species interactions to guide future management in the Miramichi River.

“…Growth data of D. vulgaris are crucial for the development of proper management strategies, yet many biological aspects of this species remain unknown (Pauly 1983), with most age and growth studies focusing on adult individuals (Gordoa and Molí 1997, Gonçalves et al 2003, Pajuelo and Lorenzo 2003, Mouine et al 2010, Dulčić et al 2011, Hadj-Taieb et al 2013. Although validations of daily ring deposition (Vigliola 1997, Villanueva andMolí 1997), TL and otolith measurements (Altin and Ayyildiz 2018), spawning dates, and pelagic larval duration (PLD; Macpherson and Raventos 2006, Galarza et al 2009, di Franco et al 2013) have been reported, only one daily growth rate study has been conducted to date (Ayyildiz et al 2015).…”

Daily growth rates and pelagic larval duration were investigated in the common two-banded seabream (Diplodus vulgaris). Fish were sampled using a beach seine from the shallow waters of Gökçeada Island, Turkey, between June 2013 and June 2014. The minimum and maximum daily age estimates were 41 and 339 d, respectively. The mean daily growth rate of young-of-the-year D. vulgaris was 0.330 mm·d–1. Our results showed that D. vulgaris exhibits a Type Ia settlement-mark with a pelagic larval duration of 29 d. The hatching period occurred from November to April. The maximum hatching frequencies were observed in winter, when the water temperature was relatively low. The natural logarithm of young-of-the-year abundance data was plotted against age, and the instant mortality coefficients were estimated. The relationships between total length and otolith morphometric measurements (otolith length [OL], width [OW], and radius [OR]) were defined by linear equations. Furthermore, it was observed that this ratio exhibited a linear relationship with OL, OW, and OR and total length and daily age.
