I found this:
He cites the example of a peach farmer who sprayed his trees with pesticide, only to have a rainstorm quickly wash the chemicals off the trees.
"The rainwater containing the recently applied insecticide ran into his pond," he writes. "The catfish did their job, cleaning the water by sucking up the pesticide; but because of their efficiency, most of them floated to the top of the pond dead. None of the fish that had fins and scales died" (ibid.).
Even commercially raised catfish are a potential health risk, he notes. "Consumer Reports tested fish bought in multiple markets in the United States. Fish are considered spoiled when bacteria counts are greater than 10 million per gram of flesh. Nearly all catfish had counts that went off the scale at 27 million per gram, even when properly prepared" (ibid.).
Dr. Russell's conclusion ". . . Although swine help clean the earth, and shellfish and catfish are ideally designed to purify the water, we don't want to eat what they clean up!" (ibid.)>

Biblically "clean fish" are generally free swimming in bodies of water. Most "unclean" fish are either bottom dwellers or predatory scavengers. The prohibition against eating scaleless fish protects against the consumption of fish that produce poisonous substances in their bodies. A U.S. Navy manual comments, "All the important fish with poisonous flesh... lack ordinary scales.... Instead, these poisonous fish are covered with bristles or spiny scales, strong sharp thorns, or spines, or are encased in a bony box-like covering. Some have naked skin, that is, no spines or scales" (Survival on land and Sea, 1944).
Many sea creatures listed as venomous (four sharks, 58 stingrays, 47 catfish, 57 scorpion fish, 15 toadfish, etc.) do not have true scales (Caras, Venomous Animals of the World, 1974). Eels—nocturnal predatory scavengers that eat "almost any kind of food, dead or alive"—would also be considered unclean (International Wildlife Encyclopedia, 1990). Eel blood contains a toxic substance "which can be dangerous if it comes "into contact with eyes or another mucous membrane" (Encyclopedia of Aquatic Life, 1988).
The biblical guidelines were designed to point people to the safest kinds of fish to eat. However, care must be taken—even clean fish should be adequately cooked before eaten. Raw fish (such as sushi or sashimi) or poorly cooked fish can transmit several kinds of parasitic Tapeworms and flukes (Black, Microbiology, 1993).
A Different Purpose
Shellfish, lacking both fins and scales, are clearly excluded by the biblical dietary laws. But why would lobsters, crabs, crayfish and shrimp, which are considered delicacies in many parts of the world, be prohibited? The answer lies in understanding the role they were designed to play in nature.
Lobsters are "nocturnal" foragers (Encyclopedia Americana, 1993). They are "bottom walkers" and "predatory scavengers" Encyclopedia of Aquatic Life) that "scavenge for dead animals" and other bottom-dwelling organisms and debris (Encyclopaedia Britannica, 1995). They are usually caught in lobster pots "baited with dead fish." Lobsters have long antennae and tiny hair-like sensors all over their bodies "that can detect specific chemical molecules in the environment (released by decaying organisms), which can help the lobster identify and locate food"—even in the dark (New Standard Encyclopedia, 1993)! Lobsters have been observed to bury a dead fish and then dig it up later, at intervals, to eat a bit more of it (International Wildlife Encyclopedia).
Crabs are referred to as "professional garbage hunters" and as "scavengers" that eat almost anything. The edible crab prefers dead fish, but will eat any carrion [dead, putrefying flesh" (International Wildlife Encyclopedia). Common shrimp, a small, delicate relative of crabs and lobsters, live by day in the mud or sandy bottoms of bays and estuaries all over the world. However, they become active at night as predatory scavengers and are "bottom dwelling detritus feeders [eating dead and decaying matter" (Encyclopedia of Aquatic Life).
These organisms were all created for a very important ecological purpose. They are, in essence, the "garbage collectors" or the "cleanup crew" for the bottoms of lakes, rivers, beaches, bays and oceans. They were not intended to be food for human beings. That is also why the consumption of raw, pickled or undercooked crabs, crayfish, snails and shrimp carries a significant risk of parasitic infections like liver flukes, which infect up to 80 percent of some rural populations in Southeast Asia (Black).
Danger On the Half Shell
There are also important and logical reasons why God created and then clearly labeled clams, oysters, mussels and scallops as unclean and inappropriate for human consumption. These creatures are found in lakes, streams and coastal areas around the world where they perform specialized roles. As stationary filter-feeding mollusks, they pump large amounts of water over their mucus-covered gills, trapping tiny pieces of food (silt, plant debris, bacteria, viruses) which they then eat (Encyclopedia Americana, "Mollusks"). As a result, "mussels and other animals feeding on microscopic particles are the ultimate scavengers of the sea" (International Wildlife Encyclopedia). Filter-feeding organisms are the "vacuum cleaners" for aquatic environments. Their role is to purify the water.
Once you understand the purpose for which God created shellfish, the reason they are unclean should become obvious. Just as you would be reluctant to make a meal out of the contents of your vacuum cleaner bag or the material that collects on your furnace filter or in your septic tank, the decision to eat shellfish should also be considered carefully! Because their method of feeding is "ideal for concentrating bacteria in sewage," in addition to collecting and concentrating pathogenic viruses, heavy metals and nerve toxins produced by plankton, these shellfish present a serious health hazard to consumers (International Wildlife Encyclopedia, Black).
How serious is the threat of disease? The American Food and Drug Administration has stated that "raw oysters, clams and mussels—so savored by gourmets—account for 85 percent of all the illnesses caused by eating seafood" (FDA Consumer, June 1991). Outbreaks of cholera, typhoid, hepatitis A, Norwalk virus, salmonella and paralytic shellfish poisoning are just some of the health problems frequently linked to the consumption of these mollusks (U. C. Berkeley Wellness Letter Feb. 1994).
Notices have been published that pregnant women, the elderly and "individuals with immune systems weakened by certain diseases (cancer, diabetes and AIDS) should... avoid eating or handling uncooked shellfish" (Consumer Research, July 1993). These dangerous and potentially life-threatening situations can be avoided by understanding and following the biblical dietary laws that prohibit eating marine organisms that lack fins and scales.

Maybe a weird website but this page does seem somewhat useful. It mentions tuna as being included, too, but that seems incorrect.
