The paper presents the first results of the analysis of archaeo-faunal remains from the monastery at Nitra-Zobor site (SW Slovakia). The majority of the 5201 analysed specimens (five samples) came from the cellar and floors of two monk’s houses from the Camaldulese Monastery of St. Joseph (1693–1782). The remainder originated from areas between the houses (one sample), layers connected to the construction and destruction of the baroque monastery (two samples), a single medieval feature (one sample) and unspecified contexts (two samples). The material is dominated by aquatic or semi-aquatic taxa (97.3%) including fish (Pisces), crayfish (Astacus astacus), otter (Lutra lutra), beaver (Castor fiber) and the European pond turtle (Emys orbicularis). Only freshwater fish such pike (Esox lucius), carp (Cyprinus carpio), Danube catfish (Silurus glanis), sturgeon (Acipenser sp.), tench (Tinca tinca), dace (Leuciscus leuciscus), and bleak (Alburnus alburnus) were identified. Large-sized individuals predominate in the assemblage pointing to the anthropogenic selection of fish, and a wealth of natural resources or favourable artificial fishponds. The representation of skeletal elements from the head, trunk and fin indicate that complete fresh fish were brought to the site. Monks consumed whole or portions of fish (traces of butchery and chewing are recorded). The assemblage from house no. 9 had an exclusively fasting character, while house no. 3 yielded bones of domestic mammals - young sheep/goat, cattle, chicken, goose and turkey. The spatial differences are explained through the context of finds, when in the latter are related with the construction and destruction of the baroque monastery. The meat of domestic mammals was probably consumed in the monastery by service staff and other secular persons that often visited and used local public services.

Forty-eight hours fasting profoundly supresses LH secretion in female rats.The following neural pathway mediating fasting-induced suppression of LH secretion has been suggested by a series of experiment:a signal associated with fasting emanting from the upper digestive tract reaches the A2 region in the medulla oblongata via afferent vagal nerve so as to activate the noradrenergic pathway projecting to the hypothalmic paraventricular nucleus (PVN); this results in an increased corticotropin-releasing hormone release to suppress LHRH release and than LH release.The PVN and A2 region of the medulla oblongata are the estogen feedback sites to activate the above-mentioned neural pathway.The estrogen feedback action on the PVN and A2 region is considered to be due to an increased expression of estrogen receptors in these nuclei after 48-h fasting.The response of gonadal axis during fasting could be due to the changes in some nutrients, such as glucose and free-fatty acids.In this context, malnutration could be a kind of stress accompanied by an increased feeding behavior and decresed gonadal activity.
