Effect of tank size on food intake and growth in individually held juvenile rainbow trout Oncorhynchus mykiss (Walbaum)

Looking for skin and gill parasites as biological tags for Atlantic bluefin tuna (Thunnus thynnus)

2008

Skin and gill parasites found in juvenile Atlantic bluefin tuna (Thunnus thynnus) caught in the Bay of Biscay, northeast Atlantic, were examined with the aim of finding biological tags. The degree of infection of different microhabitats was analyzed and the annual prevalence by species of parasite obtained. Of the specimens examined, 98% had parasites, and the gills were by far the most infected microhabitat, followed by the skin and the pectoral fin. Within the gill cavity, parasites were most commonly found in the afferent margins of the primary lamellae. Three species of Copepoda were identified, two species of Monogenea, and eleven Digenea. Thus, ten species (Digenea: Didymozoidae) and …

Effects of repeated handling, with or without anaesthesia, on feed intake and growth in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum)

2006

The effects of weekly anaesthetization with clove oil and tricaine methanesulphonate (MS-222) on feed intake and growth were examined in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum), held individually. Repeated handling without anaesthetics significantly reduced feed intake and weight gain compared with an unhandled control group during an 8-week experiment. When anaesthetics were used during handling the feed consumption and weight gain were significantly (MS-222) or not significantly (clove oil) higher than in fish handled without anaesthesia. When compared with the unhandled control group, neither of these two anaesthetics had significant effects on feed intake but, in contrast …

Sexual Abuse-Current Medico-legal, Forensic and Psychiatric Aspects

2013

Abstract Violence against women and minors is a worldwide problem that has not yet been sufficiently acknowledged. There are many obstacles especially when sexual abuses have to be evaluated. These problems are present both when victims of sexual abuse are evaluated and when sex offenders are dealt with, especially when the offenders are juvenile sex offenders (JSO). These issues give cause for great concern about prognosis, and the resulting psychosocial implications, and call for a special effort from the scientific community in identifying appropriate prevention and treatment methods. This chapter is divided into two parts. The first part deals with the forensic and psychiatric features,…

In guerra senza il nemico. Die Katrin wird Soldat di Adrienne Thomas

2015

Negli anni che vanno dalla guerra franco-prussiana all'avvento del fascismo in Italia, la costruzione ideologica dell’immaginario nazionalistico e del discorso identitario in Europa si fa pervasiva e totalizzante, investendo gli ambiti tradizionali della letteratura, delle arti ­ figurative, del discorso politico e ­ filoso­fico e modellando il dibattito pubblico, le nuove forme di espressione artistica, ­ no a caratterizzare alcuni movimenti d’avanguardia. Esito catastro­fico di questa duplice «estetizzazione della politica» e «politicizzazione dell’estetica», per dirla con Walter Benjamin, è il primo confliitto mondiale, che costituisce il principale riferimento tematico di questo volume,…

Effects of Emergence Time and Early Social Rearing Environment on Behaviour of Atlantic Salmon: Consequences for Juvenile Fitness and Smolt Migration

2015

Consistent individual differences in behaviour have been well documented in a variety of animal taxa, but surprisingly little is known about the fitness and life-history consequences of such individual variation. In wild salmonids, the timing of fry emergence from gravel spawning nests has been suggested to be coupled with individual behavioural traits. Here, we further investigate the link between timing of spawning nest emergence and behaviour of Atlantic salmon (Salmo salar), test effects of social rearing environment on behavioural traits in fish with different emergence times, and assess whether behavioural traits measured in the laboratory predict growth, survival, and migration statu…

Crescere in IPM. Il trattamento dei giovani adulti autori di reato

2017

Il trattamento dei giovani adulti all’interno delle strutture penitenziarie minorili, in seguito all’emanazione del D.L. 92/14 convertito in legge nel mese di agosto dello stesso anno, impone una riflessione e un’analisi sulle opportune modalita trattamentali non solo per i soggetti minorenni ma anche per giovani adulti tra i 18 e i 25 anni. Confrontarsi, infatti, con l’esigenza di rispondere in modo adeguato ai bisogni di una nuova tipologia di utenza e il principale compito dell’educatore penitenziario che necessita di programmi di formazione per acquisire competenze specifiche e costruire idonei percorsi trattamentali. Questi, se dotati di senso e rispondenti alle necessita di crescita d…

Growth rates of F0 and F1 larval and juvenile European seabass Dicentrarchus labrax in resonse to ocean acidification and warming

2022

Ongoing climate change is leading to warmer and more acidic oceans. The future distribution of fish within the oceans depends on their capacity to adapt to these new environments. Only few studies have examined the effects of ocean acidification (OA) and warming (OW) on the metabolism of long-lived fish over successive generations. We therefore aimed to investigate the effect of OA on larval and juvenile growth and metabolism on two successive generations of European sea bass (Dicentrarchus labrax L.) as well as the effect of OAW on larval and juvenile growth and metabolism of the second generation. European sea bass is a large economically important fish species with a long generation time…

The cis-regulatory sequences required for expression of the Drosophila melanogaster adult cuticle gene ACP65A.

2009

Post-embryonic development in insects requires successive molts. Molts are triggered by ecdysteroids, and the nature of the molt (larval, pupal or adult) is determined by juvenile hormones. The genes encoding cuticle proteins are targets of both classes of hormones, and therefore are interesting models to study hormone action at the molecular level. The Drosophila ACP65A cuticle gene is expressed exclusively during the synthesis of the adult exoskeleton, in epidermal domains synthesising flexible cuticle. We have examined the cis -regulatory sequences of ACP65A using phylogenetic comparisons and functional analysis, and find that only about 180 bp are essential, including an 81 bp intron. T…
