TL;DR: The occurrence of two ceratomyxid species in each host species supports that the genus Ceratomyxa is host-specific not only in sparids but also in serranids, which agrees with data previously obtained from Sparidae in Mediterranean Sea and from Serranidae in GBR, Australia.
Abstract: First parasitological surveys of Myxozoa are performed on the sparid saddled seabream Oblada melanura (Linnaeus, 1758) and the serranid painted comber Serranus scriba (Linnaeus, 1758) caught from the Bay of Bizerte and the Gulf of Tunis respectively in Northeast Tunisia, Western Mediterranean In this study, 6 bivalvulid myxosporean species belonging to the 3 genera Ceratomyxa Thelohan, 1892, Myxodavisia Zhao, Zhou, Kent & Whipps, 2008 and Zschokkella Auerbach, 1910, are isolated infecting their hosts Two species Ceratomyxa sp 1 ex O melanura (Prevalence (P) = 36%) and Ceratomyxa sp 2 ex O melanura (P = 13%) infected the saddled seabream and four species Ceratomyxa sp 1 ex S scriba (P = 117%), Ceratomyxa sp 2 ex S scriba (P = 67%), Myxodavisia sp (P = 83%) and Zschokkella sp (P = 56%) infected the painted comber These myxosporeans differ, in vegetative stages and/or in mature spores, from all the previously known congeneric species, and are described here on the basis of their morphological and morphometric features, their host and tissue specificities and their biogeographical distribution This is the first report of myxosporean infections in O melanura and S scriba The occurrence of two ceratomyxid species in each host species supports that the genus Ceratomyxa is host-specific not only in sparids but also in serranids, which agrees with data previously obtained from Sparidae in Mediterranean Sea and from Serranidae in GBR, Australia A member of the myxosporean genus Myxodavisia is recorded from the Mediterranean Sea for the first time, and Zschokkella spp infections have not previously been recorded from a host in Serranidae During the examination, a several cases of Co-infection among myxosporeans, both with two and three species, are provided and statistically studied Indeed, 5% of the breams and 94% of the combers are infected with more than one myxosporean parasite The relationship between myxosporean infections and some biological parameters are pointed out A higher prevalence of myxosporean infection is coincided with the peak period of spawning activity in May-June for S scriba For both hosts, analysis using Fulton’s condition factor (K) has revealed no significant difference between infected and non-infected fishes Clinically, no external signs of disease have been occurred in infected hosts, but some changes in the bile fluid, colour, and viscosity and in the gall bladder ’s tissue are examined in S scriba

TL;DR: A histological approach is used to describe hermaphroditism, dynamics of follicle development, and spawning patterns in three species from the northwestern Mediterranean Sea: the Mediterranean rainbow wrasse, painted comber, and annular sea bream.
Abstract: The usefulness and importance of histological techniques in reproductive studies have been widely discussed for gonochoristic fish species. In the case of hermaphroditic fishes, histology is a particularly important tool for the proper identification of sexual pattern (i.e., sequential, simultaneous, or nonfunctional hermaphroditism). We used a histological approach to describe hermaphroditism, dynamics of follicle development, and spawning patterns in three species from the northwestern Mediterranean Sea (Balearic Islands, Spain): the Mediterranean rainbow wrasse Coris julis (sequential hermaphrodite), painted comber Serranus scriba (simultaneous hermaphrodite), and annular sea bream Diplodus annularis (nonfunctional hermaphrodite). Development of secondary growth follicles was asynchronous in all three species, and similar peaks in spawning activity occurred between May and July. However, notable differences in sexual cycle and egg production were found. For the painted comber, hydrated follicl...

TL;DR: Analysis of gonad organization and development revealed that painted comber Serranus scriba is a functional simultaneous hermaphrodite, which indicates that this species is slow-growing and long lived.
Abstract: The population biology of painted comber Serranus scriba (Linnaeus, 1758) of the Canary Islands coast was studied to estimate gonad morphology, sexuality, age and growth. Analysis of gonad organization and development revealed that it is a functional simultaneous hermaphrodite. Its anatomy and growth pattern of the reproductive cells is similar to that described in other species of the genus Serranus , although the sequence of vesicles appearing varies during vitellogenesis. Spawning season occurred from January to September with a peak in June. Individuals reached 50% maturity at 17.3 cm TL and 95% at 22.7 cm TL. Length–weight relationship was described by the following parameters: a = 0.01 and b = 3.10, being allometric positive. Age was determined from annuli in whole forming an opaque zone and a translucent zone in each annulus per year. The high percentage of otoliths with translucent zone during the annual cycle indicated that this species presents continuous growth throughout the year. Age range was 2–11 years for fish measuring 15.0–29.4 cm TL. This species is slow-growing and long lived. The growth parameters obtained were L ∞ = 34.18 cm TL, k = 0.13 years −1 , and t o = −2.50 years. Otolith length was the best predictor of fish length, while the otolith weight was the best predictor of age.

TL;DR: The results confirm that a practice of catch-and-release (voluntary or mandatory) for S. scriba needs to be promoted among recreational anglers and factors such as surface temperature, fish size, and hook type could not explain the mortality of fish released into tanks.
Abstract: Alos, J. 2008. Influence of anatomical hooking depth, capture depth, and venting on mortality of painted comber (Serranus scriba) released by recreational anglers. - ICES Journal of Marine Science, 65: 1620-1625.Immediate (4-5 h) and delayed (10 d) hooking mortality for released fish kept in tanks was evaluated for painted comber (Serranus scriba) taken by the recreational fishery of the Balearic Islands (western Mediterranean). Results showed low rates of immediate (10.8%) and delayed (3.3%) hooking mortality, a total mortality of 14.1%. Anatomical hook location and capture depth were the most significant predictors of mortality; 70.4% of fish caught with a deep location of hook died as a consequence of the damage caused, bleeding, and long unhooking times. Fish caught in depths >16 m showed evidence of external barotrauma caused by rapid decompression, which increased the probability of death. The most common forms of barotrauma were swimbladder enlargement and stomach inversion. For fish vented with the aid of a hypodermic needle to extract excess gas, mortality was reduced by half. Factors such as surface temperature, fish size, and hook type (“J” hook vs. circle hook) could not explain the mortality of fish released into tanks. Therefore, the results confirm that a practice of catch-and-release (voluntary or mandatory) for S. scriba needs to be promoted among recreational anglers.

TL;DR: In this paper, the authors investigated spatio-temporal variability in the abundances and biomasses of four species of inshore serranids (the dusky grouper Ephinephelus marginatus, the island grouper Mycteroperca fusca, the painted comber Serranus scriba, and the blacktail comber S. atricauda) throughout the Canarian Archipelago (central-east Atlantic Ocean) with underwater visual transects.
