Summer of Chub

Just in time for summer, baby Arroyo chub have hatched in our Nature Garden pond!  Sharp-eyed Will Hausler from live animal programs spotted dozens of tiny black fish darting around in the shallows at one end of the pond.  He shared his discovery with Leslie Gordon, our live animal programs manager, who arranged the chub introduction and has been keeping tabs on them.

Her first thought was that they must be the offspring of the chub we released in March, but she wasn’t sure. It’s hard to tell what kind of...

Arroyo #Chubwatch 2015

After three long years of planning, 45 arroyo chub were finally released into the Nature Garden's pond last week.

Arroyo chub, Gila orcuttii, are a native freshwater minnow found only in the coastal streams of Southern California, says Chris Thacker, Museum Curator of Ichthyology (fishes). They are classified as threatened in this native range and are noticeably missing from the lower reaches of the Los Angeles river. So, when it came time to think about fish in the Nature Gardens pond, all our scientists and educators wanted Arroyo chub.

 
The chub were transported from the...

Urban Foraging: Carp Caviar from the L.A. River!

Ask me where my favorite spot to explore urban nature is in Los Angeles, and I'll almost always say the river. This is particularly true during, and after, our seasonal rain storms. We're used to extreme heat episodes, wildlfires, and the odd earthquake* or two. But, by and large, us Angelenos are unaffected and unimpressed by the elements. Going down to the river after a good rain, you get a rare chance to see, hear, and feel the raw power of nature.

*Anyone else wake up abruptly last Monday morning after the 4.4 trembler, wondering how much water you could salvage from your toilet's holding tank?

Piranhas Found in L.A.!

Piranhas are the stuff of B-movies, sensationalized nature television, and the tropical rainforest. Most would think they have little bearing on life here in L.A., however as I learned last week, this is not the case.

Piranhas are here in L.A.! They are sometimes confiscated from pet stores and, on occasion, they are even found in our waterways. The Museum's Ichthyology collection houses over 30 confiscated piranha, and at least one that was caught in the "wild." According to the collections record, this Red Piranha (see below) was netted from "Simi Valley Public Golf Course, Lake B." It was collected on April 28, 1988 and measured 275mm (almost 10 1/2 inches)! Most interestingly the...
