As the casein tempera, it is considered that some Pompeian wall. paintings were made with this particular technique, which in medieval. times translated into a glue made of lime and cheese which stands for the. modern equivalent of calcium caseinate glue.
APPLICABLE INTERNATIONAL LAW The Cormorant is protected under the 1916 Migratory Bird Treaty with Canada, indirectly under the Ramsar Convention, and the Migratory Bird Treaty Act of 1918 (MBTA). The cormorant receives no protection from the Convention of Migratory Species or CITES.hile the Ramsar Convention and the Migratory Bird Treaty with Canada remain possible avenues for international protection of the cormorant (see infra), it is the Migratory Bird Treaty Act of 1918 (MBTA) that is the primary instrument of international law concerning the migratory birds in North America.
Cormorants consume a wide variety of fish species, usually reflecting their availability at inland fisheries. Cormorants commonly take fish between 5 and 15 cm (2 to 6 inches) in length, but have been recorded eating fish of over 40 cm (16 inches) and eels of over 60 cm (24 inches) long.his is why fishery managers commonly resort to stocking to increase fish densities in their waters. The extent to which cormorants might affect a fish stock, and thus catches, will depend on the duration and level of the predation and the numbers, sizes and species of fish removed.
