This study aimed to compare the fertility of eggs between artificially matured female silver eels that spawned spontaneously and those were by manual stripping. The effects two methods spawning on ovulation fertilization rate also investigated. For this purpose, 18 wild European captured in Bonello lagoon (North Adriatic Sea) carp pituitary extract-injected undergo sexual maturation ovulation; a final injection 17,20β-dihydroxy-4-pregnen-3-one (DHP) was administered when at least 30% oocytes...
The reproductive performances of silver European eel in term gonad development and egg production, employing slow-release implants with the androgen 17-MT (1 mg) combination traditional weekly injection carp pituitary extract (CPE) was evaluated. Wild female eels (Anguilla anguilla) underwent a standard induction protocol CPE were randomly divided into three groups (N-group, no implant; Y-group, control, C-group, treatment). results showed that 17-MT-treated females (Y-group) reproduced...
This investigation focused on an episode of chronic mortality observed in juvenile Huso huso sturgeons. The examined subjects underwent pathological, microbiological, molecular, and chemical investigations. Grossly severe body shape deformities, epaxial muscle softening, multifocal ulcerative dermatitis were the main findings. more constant histopathologic findings moderate to rarefaction disorganization lymphohematopoietic lymphoid tissues, myofiber degeneration, atrophy interstitial edema...
The European eel is a critically endangered teleost fish with very poor success rate for captive breeding and artificial reproduction. Therefore, to support its conservation, new strategies are needed ensure fertilization. Objective analysis of sperm motility may be critical as it potentially represents one the most important reproductive quality parameters. Spermatozoa acquire once in contact hyperosmotic solutions saltwater, yet exact mechanisms role temperature still clarified. main aim...
During the 1970s and 2010, population of Anguilla anguilla declined significantly, species is now classified as a critically endangered by International Union for Conservation Nature (IUCN). Considering its social, economic, ecological importance, it necessary to understand biological mechanism that controls dynamics, in particular passage from resident phase migratory phase. this their life cycle, environment plays key role maturation spawners which will eventually undertake long spawning...
This study evaluated the growth performance and survival rate of Anguilla anguilla glass eels reared in 4750 m2 earthen ponds dependent on trophic resources provided by natural macrobenthic populations. Two (M ponds) had mostly muddy-soil bottom whereas other two (S sandy-soil bottom. A total 4795 pigmented (0.73 ± 0.26 g) were stocked, at a density 1.6 fish/m2. After 360 days growth, S exhibited final mean body weight (15.57 5.36 significantly higher than those seeded M (9.85 4.11 g). Mean...
The European eel (Anguilla anguilla, Linnaeus 1758) is a catadromous fish with significant cultural, scientific, and commercial value. protection of this species particularly difficult because the biology life cycle remains unknown in many aspects. (A. anguilla) population has declined alarmingly over past 30 years; condition led to questions about long-term welfare species. This work aims perform histological analysis on gonad samples from eels coming four different lagoons North Adriatic...
is a commercially valuable species. It overexploited in the natural environment and considered to be an innovative species for aquaculture. However, large-scale farming generally designed only based on economic requirements, disregarding any form of enrichment that induces behavior aquatic Although many studies have shown influence environmental terrestrial vertebrates, fish, cephalopod mollusks, information effect body patterns
European eel Anguilla anguilla is among the highly valued species for aquaculture. Since its peculiar biology, it not yet possible to complete whole life cycle in artificial conditions and supply depends entirely on wild catches. In last 50 years this has suffered a population reduction of 99 % mainly due overfishing. conservation perspective, fundamental importance improve aquaculture production eel, avoid extinction preserve residual genetic variability, allowing at same time fulfilling...
The European eel, Anguilla anguilla (Linnaeus, 1758), is a species of high conservation and commercial value. Also, with aquacultural value, it was one the most farmed in Europe before its decline. Conservation measures for this are currently being implemented, some which release adults to allow them migrate spawning grounds artificial reproduction minimise impact overfishing. Much progress has been made regarding closing life cycle, but several problems remain be solved, such as weaning...
Abstract The reproductive performance of Octopus vulgaris broodstocks fed two different diets (mixed fish [F group, BW 1,048.14 g] or mixed crustaceans [C 998.44 g]) was analyzed using an experimental recirculating aquaculture system consisting a tank equipped with spawning and incubation chambers. A total 8 females (F1–4; C1–4), males (M1–M8) were selected. DI the C group significantly (p < 0.05) higher (3.0 ± 0.29%) than F (2.16 0.67%). SGR in (1.43 0.12%) (1.18 0.25%). Egg clusters,...
Because of its complex life cycle and due to multiple stress factors, the European eel is suffering a dramatic decline has been declared Critically Endangered by IUCN. A possible way address this problem could be relieve pressure on natural stocks implementing mass production artificial breeding protocols. previous study based direct observation parentage assignment underlined presence an allegedly hierarchic structure among males in semi-natural mating conditions, with consequent bias F1...
The eel (Anguilla anguilla) population in Europe has declined dramatically since the 1980s and shows no signs of recovery. There are several threats to this species: migratory barriers, loss habitats, hydroelectric dams, overfishing, illegal trade. As a result, become part ICUN endangered species is protected by various institutions. Information data on maturation stage needed monitor silver escapement assess trends. In sampling activities spanning from 2012 2022 index was calculated 1852...
