from nest boxes is highly important. The chicks fledged from nest boxes during
the summer of 2001 represent an equivalent reproductive output of 101 pairs
breeding in natural sites, and an effective doubling of the colony size.
For each population, data were obtained on the following parameters: adult
nest attendance; adult foraging success; energy expenditure of incubating birds
(weight loss method, Bolton 1996); incidence of egg-neglect; duration of
individual incubation shifts; duration of total incubation period; rate of food
delivery to the nestling; duration of nestling fasting periods; rate of chick growth
(body mass); rate of chick development (bone and plumage development); mass
of the chick on fledging; duration of the fledging period.
Life cycle of two migratory Anguilliform species - Anguilla anguilla (L.) and
Conger conger (L.) - in the North Atlantic
FCT – 2/2.1/MAR/1728/95
The main goal of this project is to contribute for a better understanding of the
biological cycles of the species Anguilla anguilla (L.) and the Conger conger (L.).
In relation to the first species we intend to its transatlantic migrations. Concerning
the second species we intend to study the relation between spawning region(s),
distribution, duration of larval phase, sexual differentiation, fecundity and growth.
MAROV - Mapping of Marine Habitats of the Azores using Robotic Ocean
Vehicles.
PDCTM/P/MAR/15249/1999
The key scientific result of the project is the generation of detailed maps of a
set of Sites of Community Importance (SCIs - EU Habitats Directive) in the
Azores, with the objective of deriving guidelines for their management. The
project will determine habitat attributes that significantly affect the distribution and
dynamics of harvested species. Special attention will be given to determining
valuable zones for fish reproduction (for example, groupers and trigger fish), and
monitoring fish community structure and abundance. The project is highly
multidisciplinary, displays a clear symbiosis between marine science and
technology, and implements the key components in the chain that gives support
to modern systems for marine habitat mapping: data acquisition, pre-processing,
and transmission, multi-scale data integration, and information processing and
dissemination.

Small pelagic fishes from Azores: Biology and Fisheries
FCT – 4.70.94/PRADIC-CT
In the past, the monitoring of the small pelagic fishery in the Region has been
sporadic, hence, this fishery is currently poorly described, the existing information
