How Fish Smell and Breathe

I've completed part of my term project, focusing on the "nostrils," or more properly, nares in fish. I based my findings primarily on Koi anatomy. Species vary. In species with barbel (the hair-like appendage from sides of mouth, like this koi) are also used in the detection of scent / food as well.750 pixels750 pixelsAdding longer cilia. Needs some trimming.Just completed this morning... the model...

Aquaculture - Koi Diet

While studying on anatomy of fish and the technical definition of "barbel" which is used for the fish sense of "smell" in location of food and whatnot, I came across this golden tidbit on another website.The Fundamentals of Feeding Koi and GoldfishBy Stephen M. MeyerFeeding OptionsCarp and goldfish evolution has seen to it that the proper functioning of their digestive systems requires dietary variety...

Southeastern Plankton Monitoring Network (SEPMN)

On April 11, 2007, I gathered my first plankton sample (on my own) as instructed by NOAA's SEPMN (Southeastern Phytoplankton Monitoring Network), Jeff Paternoster. Data is collected and monitoring for toxic phytoplankton blooms along the Atlantic, and entered into the national database. It's a network of volunteers, and NOAA provides training and equipment free of cost.The slide contained numerous...

Hybrid Striped Bass - White Grub and Yellow Grub

Two snail types which pose threat to hybrid striped bass culture.While working around the ponds at BCC, I'd seen one pond where quite a number of the ram's horns snails lay along the embankment. I went back to collect some for display and identification. (I collect mollusk shells). While there, instructor John Baka informs me of a second disease aside of yellow grub (caused by Ram's Horn), it is the...

Koi - show fish

Images enlarge to full resolution.Koi, Japanese Carp, show fish (youtube upload). These were taken at the Brunswick Community College Aquaculture center, and are currently being kept in a recirculating system.The fish are large. Though related to Goldfish, they grow up to over a ft in length. These particular fish measure over ft in length.One student remarked today, though large enough for food-fish,...

Dolphin Slaughter

Here's an excerpt from an article on artificial intelligence, and includes dolphin intelligence in comparison with human.Is Artificial Intelligence Possible?By Tommy ConnollyBy many of the physical methods of comparing intelligence, such as measuring the brain size to body size ratio, cetacean surpass non-human primates and even rival human beings. For example “dolphins have a cerebral cortex which...

Spirogyra

Recently, the instructors at Brunswick took myself and another student to the ponds and showed us certain common elements that are important to proper pond management and care. One of the important things I learned was about filament algae, and the threat it poses to fish.Pond with filamentous algae, at Brunswick Community CollegeEnlarge to full 2816 x 2112 pixels resolutionFilamentous algae, at Brunswick...
