  Many galaxy properties are known to correlate with the environment in which
the galaxies are embedded. Their cold, neutral gas content, usually assessed
through 21cm HI observations, is related to many other galaxy properties as it
is the underlying fuel for star formation. With its high sensitivity and broad
sky coverage the blind Arecibo Galaxy Environment Survey (AGES) survey brings
significant improvement to the census of HI properties of galaxies in a wide
range of environments, from voids to the core of a massive cluster. Here we
present an HI census over a volume of ~44000 Mpc$^{3}$ towards the merging
cluster Abell 1367 and the large-scale structure (LSS) surrounding the cluster
out to cz = 20000 km/s. The survey is sensitive down to a column density of
N$_{HI}$ = 1.5 x 10$^{17}$ cm$^{-2}$ for emission filling the beam and a line
width of 10 km/s. As an approximate mass sensitivity limit, a member of A1367
(at a distance of 92 Mpc), containing M$_{HI}$ = 2.7x10$^{8}$ M$_{\odot}$
distributed over a top-hat profile of 50 km/s width would be detected at
4$\sigma$. The results are analysed in combination with optical spectroscopy
data from SDSS which we use to estimate the local galaxy density based on the
Voronoi-Delaunay method. In total we detect 457 HI sources, 213 of which are
detected for the first time by the AGES survey, 134 of which are presented in
this article for the first time. 225 of the detections are in the cluster and
232 in the remaining volume surveyed. Here we present the full catalogue of HI
detections and their basic properties, including optical ones. We concentrate
on the difference between the cluster and the foreground and background LSS,
revealing a continuous correlation of HI detected fraction (and HI deficiency)
with local galaxy density, independent of global environment.
