directions. Having certain tendencies, he must move along their lines to the limit of their potentialities."

So, there you go

Topic that came up in class tonight...  One of the "mini-project" topics that my students are addressing is the idea of "fish as pets", the idea being to find out a little about the natural history of the species that have come to be popular in people's homes.  A number of the fish that students have chosen to examine are tropical marine species, and we had a discussion tonight about the conservation impacts that the aquarium trade is having.  And then this.  A new paper appearing in Marine Policy examines just that issue, concluding that international law is not doing an adequate job of protecting reefs and reef species from decimation from collectors.  Collectors remove some 30 million fish per year, belong to perhaps 1,500 species.  Since many collected fish will die before reaching markets, collectors overharvest to be sure they have enough to meet their needs.  Some fish, like the Banggai cardinalfish, have disappeared from much of their previous range.  The authors recommend that to deal successfully with the issue, pressure must be exerted on the U.S. market which accounts for over half the trade in reef fish.
