NPR/NGS RADIO EXPEDITIONS Barbara Block -in CA -Monterey Bay Aquarium TUNA Feb. 11, 1997 BB = Barbara Block CF = Charles A. Farwell AC = Alex Chadwick G 00:46-2:14 -ambi kids @ monterey aquarium, music in bg 2:44 BB -what is neat what is going on is that the tuna here are patrolling waiting for the first bite of food to come in and once they finish feeding -what you are going to see is we are going to drop in the water column to the bottom of the tank and what is going to happen -and what's going to happen is that one the food hits the water they are going to establish the normal pattern that we think they feed in nature with -and then watch them come up -(AC -here they are) there they go. and they are going to come up from the bottom from the depths (?) (AC -they are dropping in what? squid?) they are dropping in squid -lots of squid (AC -ah!) 3:18 AC -tell me what the fish are doing -what the tuna are doing ¬ BB -what the tuna are doing is coming up from almost the bottom of the tank to head up and hit the squid from below. so what they do is silhouette the squid with a light at the top of the tank. they are actually coming up as they feed in nature -from deeper in the tank and then coming up towards the squid. so watch a large tuna. get your eyes on a large tuna. now what they are doing is coming down and then coming back up -and it is sort of hard to see. and almost all of the approaches to the squid are coming from below and then up at the squid. AC -there they go G 3:55-4:14 ambi -kids watching with music in bg 4:16 AC -they are amazingly fast (BB: they are) for big animals BB -they are -they are actually quite deep in the tank now ¬ let's see if they come up now -there is a lot of food on the surface -there you go -there are some large tunas on the surface. ok. they leave their pectoral fins out and they are actually flying through the water like airplanes getting lift from the pectoral fins. and despite their large size and bulk they are very maneuverable. now you are getting a beautiful view. this is not any different from perhaps what you would see in nature. coming out of the murky depths and picking off the squid 4:52 4:53-5:00 ambi bed 5:01 AC -do they like to feed near the surface like this? BB -well actually this particular species of yellow fin tuna ¬what we have noticed in the wild is that they like to be down at depths and then come up quickly to the surface and then go back down again. think of them as being a bit skittish of the surface. and if you watch in here, even in the tank you've got that phenomenon happening. you don't see yellow fin tuna right at the surface. what you have are the big yellow fin tunas down lower in the tank in about 6 to 10 feet and then coming back up to get the squid...and so for the public what you get is a real view of how this system works in the open ocean. you've got mixed groups -bonitos (?) and tunas, barracuda along with the sea turtles and molas and the interactions here at a feeding frenzy are probably similar to what one might see in the open ocean. 5:50 G 5:51-6:06 ambi -kids, music in bg -esp. good bc child saying FISH, look at the FISH (I think -a bit faint) 6:07 BB-the goal here at the aquarium this spectacular view ¬this window onto the open ocean (good bc of the music in bg) to get an idea at what these animals are doing so that we have an appreciation for the organism that is distinct from its view in a can. 6:26 AC -i have been to the Boston aquarium for instance, and others, but i have never seen tuna at an aquarium. BB -in japan there are tuna in... (Notes truncated)
