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...

Vorticella - Protozoan Parasite

One of the protozoans I recently photographed, is Vorticella.A few evenings ago I captured multiple videos with the same organism.. heavily populated slide with these flower-like contractile stalk organisms.http://pirx.com/droplet/gallery/vorticella.html contains a clear photograph of this organism I compared with, among others on the web."Vorticella is a sessile, peritrich ciliate. Disturbed contracts...

Fish Dissection

Preliminary Student Dissection of FishHead and Gills -- high magnification and some microscopy of gills, and various sections from gills to head.This is for my term project in Aquaculture Practicum. I'm closely observing details as I go through the fish and then to study about certain features and processes in fish anatomy, and last create a model/s of those important parts of a fish.Warning: Some...

Teaching a man to fish...

Today I visited the local fish market for "fish heads" to do part of my fish dissection project. I want to investigate how the brain of a fish works and interconnected. They were very kind and supplied me with a bag full of fish heads, on the house. *smile*I saw they had this neat bumper plate in the wind...

Yellow Perch

Yellow Perch ProductionModified in parts from class notes by Dr. Doug Holland, Aquaculture Program, Brunswick Community CollegeYellow perch (Perca flavescens) is a relatively new species to aquaculture. This species is widely distributed, ranging from Nova Scotia to South Carolina along the Atlantic seaboard and throughout the Great Lakes region and as far west as the Dakotas and Nebraska. Commercially, it has been cultured in the upper Midwest, and in the Eastern US from Pennsylvania to South Carolina.The...

Rainbow Trout Culture II

Rainbow Trout Culture IINotes modified from Dr. Doug Holland, Aquaculture, Brunswick Community College.Feeds and FeedingMany companies manufacture high quality trout feeds. Feeds in all particle sizes are available, beginning with crumbles #00, 0, 1, 2, 3, 4 which are best suited for fry and small fingerlings. Advanced fingerlings, larger fish and broodstock should be fed floating or sinking pellets...

Paramecium

I'm taking another blind shot at this, but this creature I've regularly seen under freshwater slides -- must be Paramecium.ParameciumFrom Aids to the Recognition of Fresh-Water Algae, Invertebrates, and FishesIn school I was taught Paramecium had the shape of a "shoe," and this creature does at times while its on the move.But its an oval-shaped creature, sitting still. There are many species of Paramecium,...

Protozoa, their role and impact on Aquaculture

Protozoa, their role and impact on AquacultureProtozoa means “first animals,” and are described as unicellular (single cell, or acellular) eukaryotes [eukaryotes are distinguished from prokaryotes by the structural complexity of the cells - characterized by having many functions segregated into semi-autonomous regions of the cells (organelles), and by the cytoskeleton]. Protozoa exist either as individuals...
