“…The endogenous reserves were depleted moderately fast (78% of yolk and 35% of oil globule) until mouth opening, by 4 dph. Data reported by Ben Khemis et al (2006Khemis et al ( , 2013 were 64% and 36% at 5 dph. The typical growth pattern of this mullet species with slow increases in body mass rates during the first inflexion point (at 22 dph; SGR 3.93%, present study), and an extended mixed endo-exogenous feeding period (until 13 dph) seems to be a common feature in early larval stages of the Mugilidae family.…”

“…Artemia sp. nauplii (0.3-0.5 prey mL -1 ; Ben Khemis et al, 2006) were supplied from 6 dph, which was gradually replaced with enriched meta-nauplii between 13 and 25 dph (1 prey mL -1 ) and 0.1, 0.2 and 0.5 mm commercial diets ad libitum (Skretting, Burgos, Spain) which were the only food offered to larvae from 25 dph onwards.…”

“…Traditional extensive culture systems, departing from captured wild fry, have been described as the most efficient and economic way of producing mullets Drake 1990, Yúfera andArias 2010). Chelon labrosus is an interesting species to diversify aquaculture, and the success of sustainable productions of the Mugilidae could also be a result of their reproductive strategies, food preferences and feeding behaviours (Albertini-Berhaut 1973, Bruslé 1981a,b, Drake et al 1984, Crosetti and Cataudella 1995, Ben Khemis et al 2006.…”

Summary:The main ontogenetic and functional changes of the digestive and visual systems of Chelon labrosus during the first three months from fertilization until 99 days post-hatch (dph) are described. An extended slow growth pattern (3.93%) during the first three weeks of larval life was discernible. A long transitional period of mixed endo-exogenous feeding was noticeable until 13 dph. The majority of organ systems and structures (eye, digestive system, liver, pancreas, thyroid and others) were developed and functional before first feeding (mouth opening at 4 dph). First differentiation of gastric glands was detected at 16 dph, with the appearance of a noticeable pyloric muscular portion or typical gizzard and first developed pyloric caeca from 23 dph. The presence of pinocytotic supranuclear vesicles (5 dph) was still visible in the posterior intestine until the third month of life. The eyes exhibited early differentiation and functionality (pigmentation, first cone-type photoreceptors) during the lecithotrophic phase (2 dph), and development of all typical retinal layers containing different retinal cell types was progressively discernible from 16 dph onwards. From this time, rod photoreceptor precursor cells were incorporated into the basal region of the outer nuclear layer, and increases of two types of photoreceptors (cones and rods) were detected from 23 dph.Keywords: thick-lipped grey mullet; Chelon labrosus; embryo; larva; growth; yolk; ontogeny; digestive, vision; histochemistry.Ontogenia e histoquímica funcional de los sistemas digestivo y visual y de otros órganos durante el desarrollo larvario de la liseta, Chelon labrosus.Resumen: El objetivo del trabajo se centró en describir los principales cambios ontogénicos y funcionales de los sistemas digestivo y visual de Chelon labrosus, durante los primeros tres meses de vida larvaria, desde la fertilización hasta 99 dias después de eclosionar (dde). Se observó un largo periodo de reducido crecimiento (3.93%) durante las tres primeras semanas de vida, y una amplia fase de alimentación endo-exotrófica (hasta 13 dde). La mayoría de sistemas, órganos y estructuras tisulares (ojo, digestivo, hígado, páncreas, tiroides, entre otros) se evidenciaron desarrollados y funcionales antes de iniciarse la primera alimentación (apertura de la boca a los 4 dde). Las glándulas gástricas se desarrollaron a partir de 16 dde y la porción pilórica muscular o típica molleja y los ciegos pilóricos eran visibles a los 23 dde. La presencia de vesículas proteicas supranucleares pinocitóticas era evidente en el intestino posterior (5 dde) y hasta el tercer mes de vida. Los ojos presentaron una precoz diferenciación y funcionalidad (pigmentación, fotorreceptores tipo conos) durante la fase lecitotrófica (2 dde) y se observó un desarrollo progresivo de todas las capas retinales, y conteniendo los diferentes tipos celulares desde los 16 dde. A partir de este periodo, algunos precursores de fotorreceptores tipo bastones se incorporaron en la región basal de la capa nuclear externa, y...

“…Moreover C. labrosus usually supports artisanal fisheries (Cardona et al, 2008). Since they are consumers of low trophic level species, they can be used in an economic and efficient way in extensive culture (Khemis et al, 2006). PCBs studies on this species are scarce, and only laboratory studies have been made (Narbonne, 1979).…”

“…This species is omnivorous (feeds mainly on benthic diatoms, epiphytic algae, small invertebrates and detritus) (Zouiten et al, 2008). More recently, the research in C. labrosus has increased due to its economic relevance and to its potential to be cultured in fish farms (Boglione et al, 2006;Khemis et al, 2006;Zouiten et al, 2008).

Thicklip grey mullet, Chelon labrosus, is an important commercial fish species and has been studied worldwide. However, no recent studies have been made regarding polychlorinated biphenyls (PCBs) in wild C. labrosus. Due to that, the concentration of 13 PCBs congeners were measured in muscles and livers, of males and females, of C. labrosus of different ages, allowing the estimation of PCB bioaccumulation throughout the species lifespan, in the Mondego estuary, a southern European temperate estuary. Male muscle sample concentrations ranged from 32 to 96 ng g -1 (lipid wt.) and in females from 32 to 62 ng g -1 (lipid wt.). In male liver samples concentration ranged from 106 to 158 ng g -1 (lipid wt.), while female concentrations ranged from 88 to 129 ng g -1 (lipid wt.). The most abundant congeners presenting higher percentages in all samples were CB 138, 153 and 180. No significant differences were found between the concentrations in both sexes, but muscle and liver PCB concentrations in males tended to increase with age whereas in females concentrations remained stable throughout the species lifespan. Significant differences were found between concentrations in muscle and liver.
