In recent decades, biologists have sought to tag animals with various sensors study aspects of their behavior otherwise inaccessible from controlled laboratory experiments. Despite this, chemical information, both environmental and physiological, remains challenging collect despite its tremendous potential elucidate a wide range animal behaviors. this work, we explore the design, feasibility, data collection constraints implantable, near-infrared fluorescent nanosensors based on DNA-wrapped...
Subclass Elasmobranchii belongs to an old evolutionary class of Chondrichthyes that diverged 450 mya, presenting a wide diversity reproductive strategies while preserving the ancient mode internal fertilization. Despite such success, many species in this group are at serious risk extinction. Understanding principles sperm progressive motility and physiology vertebrates is crucial for advancing future assisted techniques safeguard deepening our understanding evolution reproduction. possess...
Elasmobranchs are one of the most endangered vertebrate groups on planet, but despite this situation use reproductive techniques in elasmobranch conservation strategies has been scarce. Among these techniques, sperm preservation is a potential tool for ex situ and aquaria sustainability. However, there no widespread protocols sperm, shark cryopreservation never achieved before. Here we present establishment successful tested several species. We have formulated extender that can be used...
A specimen of angular roughshark Oxynotus centrina has been kept successfully in captivity for the first time. Over a period 24 months, preyed exclusively on contents elasmobranch egg cases, suggesting specialized trophic niche.
The superorder Batoidea (rays, skates, and relatives), constitutes one of the most threatened group vertebrates. Strengthening ex situ conservation programs developed in research centers public aquaria could be a way addressing this situation. However, captive breeding must improved to prevent capture wild animals develop proper reintroduction strategies. Sperm extraction artificial insemination are two techniques commonly used other species, which also rays like. different reproductive...
The chondrichthyan fishes, which comprise sharks, rays, and chimaeras, are one of the most threatened groups vertebrates on planet. Given this situation, an additional strategy for protection these species could be ex situ conservation projects developed in public aquaria research centers. Nevertheless, to increase sustainability develop properly reintroduction strategies, captive breeding techniques, such as sperm extraction artificial insemination, should developed. These techniques...
There are numerous reports of billfishes spearing objects, marine organisms, and even humans. Whether or not this behaviour is intentional and, if so, what its functional meaning, open questions. In 2016, an adult blue shark (Prionace glauca) was found to be killed by a juvenile swordfish (Xiphias gladius) in the western Mediterranean. Here we report on three more recent cases involving both species same area. February 2017, male stranded Garrucha (Spain) with fragment swordfish’s rostrum...
The European eel (Anguilla anguilla) is a commercially valued species for aquaculture. Over the past decades, it has experienced drastic reduction in its natural stocks. Thus, breeding captivity considered essential, nowadays, to guarantee aquaculture and reduce pressure on populations. Traditionally, been sexually matured by means of weekly hormonal injections, which cause stress fish. purpose this research study was assess use osmotic pumps as new method induce sexual maturation male...
Chondrichthyans, which comprises elasmobranchs (sharks and rays) holocephalans (chimaeras), are one of the most endangered group vertebrates on planet. Ex situ conservation programs, such as captive breeding, tools that can be used to improve status some sensitive species belonging these groups. However, use reproductive techniques is necessary when planning sustainable breeding programs in controlled environments. In recent years, our has described protocols achieve viable sperm extraction...
On 15 March 2021, a male Hexanchus griseus was incidentally captured by commercial bottom trawler at 550-730 m depth in the Gulf of Valencia (Spain). The specimen measured 251.8 cm total length, weighed 86.2 kg and its reproductive system fully developed, characterizing it as smallest mature bluntnose sixgill shark recorded Mediterranean Sea. hosted ectoparasitic copepod Demoleus heptapus. Remains Stenella coeruleoalba calf were identified stomach content applying molecular methods. feeding...
Chondrichthyan fishes, which comprise sharks, rays, and chimaeras, are one of the most threatened groups vertebrates. Given this situation, possible strategy for protection these species could be use ex situ conservation projects. However, to develop sustainable programs, captive breeding techniques, such as sperm extraction its preservation, should used. Two main obstacles must overcome techniques: first, lack knowledge scarce previous work focused on gametes from animals; secondly,...
