「Head and neck」with「plugging orifice and emissions」may refer to the manner in which FISH propagate and what causes ejaculation: the triggering mechanism for male fish ejaculation is the proximity to the eggs of a female, any female of the species—she may have even already departed, but if her pheromones linger in the water, sperm is spawned and spurted. Close proximity, even for a few moments, causes male fish to blast their wad into the surrounding waters. Female「plugging orifice」pheromones are sensed by the male「head and neck」with resulting「many emissions」. The action of pulling in a net full of fish often brings many males and females of the same species into close proximity, causing instantaneous ejaculation triggered by the female pheromones, all in all「many emissions」by both sexes.
　Glyph means FISH, a type of animal not often found in rice paddies today despite the central element.「head, and gills (flaps of boneless meat), plugged orifice with many emissions」or「head and neck in danger, looking up」with「filled mouth」and「many emissions」describes the act of hooking a fish with bait in the mouth, and while fish may not actually be looking up, not many fish were hooked and caught by fishermen situated below the fish in the old days before scuba gear. Gill nets also snag a fish by the neck and head. And from a human's perspective, but not the fish's perhaps, a「mouth filled」nearly all the time with water.
　It should be mentioned that carp are perhaps the only fish species hardy enough to survive in rice paddies feeding on mosquito larvae, although the term「fish」might be applied loosely to any aquatic animals living in rice fields, including freshwater prawns, crayfish, crabs, turtles, bivalves, frogs, and possibly insects. Thousands of other fish species cannot survive in rice paddies. Some evidence suggests that the Chinese began raising carp in rice paddies about 3,500 years ago near the end of the Shang Dynasty, both to eat and to keep the mosquitoes under control. Initially, the fish may have been swept into paddies together with flood waters from nearby rivers.
　The「blocked or closed orifice」element can also refer to the entrance to the gullet of the animal, something particularly noticeable as a characteristic of FISH simply by looking into any fish's wide open mouth. Not all, but most other animals do not have a closed esophageal orifice, and instead close the mouth as the means of regulating what enters the digestive system. FISH obviously do not keep the mouth closed or else they cannot extract oxygen dissolved in water with gills, hence the need for a「blocked orifice」in the back of the mouth instead. Other than while swallowing and activating the epiglottis, air-breathing animals maintain an open gullet to allow air intake into the lungs, organs not possessed by most species of FISH. Most fish do not survive too well in rice paddies, although carp are sometimes used to quell mosquito larvae outbreaks.
　FISHING is often performed using a stiff rod held in one or both hands, and these elements are also「head and neck with filled orifice, screwing orifice and many emissions」that refer in hundreds of glyphs to sexually suggestive double-meanings, much as do「tree, woody (木)」「thread, ejaculation (糸)」「grain, seeds at tip of stalk (禾)」and so on. Use your imagination for the stiff rod, bending rod, fishy smells, casting line, baiting, getting a nibble, wriggling, trolling, foul hooking, snagging, snaring, trapping, or any other concept associated with FISHING. A fish itself also become euphemistic of a slimy, slippery wet penis just pulled from a wet spot, complete with the meatus resembling the fish's opening and closing mouth, and gills resembling the glans flange and prepuce, a client as a「sucker」is born every minute, or so. Analogy of the female as the bait of a proprietress,「filling mouth」with「head and neck of slippery meat」and「many emissions」or filling some other wet orifice with a fishy odor, is obvious…why do you think they call them 'hookers'?
In its original parlance, describing a thing or situation as "smells fishy" did refer to having probable cause for extreme doubt and suspicion, but most folks do not realize why innocuous fish are so maligned in this manner. A fishy or pungent-smelling discharge from the vagina or penis may signify the presence of an infection, so caution was advised...and still is today.
