It would appea that a goodly potion of Oegons salmon and steelhead angles ae quite a bit moe concened about the fish they catch today than helping plan fo fish fo tomoow Each peson who angles fo eithe of these fish is equied to have a salmon steelhead license which also doubles as a catch ecod cad and is equied by law to etun it to the Commission The infomation contained on it is impotant to biologists tying to plan fo the futue of these fine spot fish The catch ecod cads not only give manages a pictue of the total spot catch fo the yea but make it possible to calculate the catch by steam and aea The next question might be "Who caes?" Evey angle who wants to have a chance of catching a fish in the futue should cae The ecods do seveal things Fist they give a quite good estimate as to the total catch fo the yea This is extemely impotant to know when it comes to negotiations with dam buildes commecial inteests and othes who want to distub fish habitat o take the fish diectly Secondly the catch ecods when boken down by steam may be an ealy waning if touble is bewing A dop in poduction by a steam may indicate the steam has poblems and steps need to be taken to modify its chaacteistics o to put a stop to some type of envionmental degadation that might be taking place Data fom the catch ecod cads can also give diection to the Commissions hatchey pogam by indicating whee plants have been successful o pehaps whee the inceased catch may indicate an acceleated pogam is desiable With all of this in mind it would seem that any angle who caes at all about the futue of his fishing would be eage to get these cads tuned in to the Wildlife Commission as soon as possible afte the fist of the yea But not so! Though the deadline fo submitting these cads is listed as Mach 1 the etun by that time this yea was a measly 15 to 20 pecent Put in eveyday tems a petty lousy showing! Its a petty sue thing that moe angles than that caught fish It might be a bit moe undestandable if it wee only the nonangles o even the noncatches who didnt send the cads in but appaently a quite lage goup of those who managed to succeed in havesting pat of the cop cant be botheed to clean out thei billfold Actually evey cad contains impotant infomation If you bought a salmon steelhead license but fo some eason didnt get to go fishing thats an impotant piece of infomation If you fished but weent successful thats impotant also and obviously if you fished and wee successful thats impotant to know Weve head some angles say that they dont send the cad in because then the numbe of fish they caught will be tallied and thei favoite steam will get too good a eputation Could be; howeve it could also eveal that thei steam dopped in total poduction and that it needs some help The lack of catch on a steam might be intepeted by some as indicating that the steam isnt poducing any fish so it might as well be dammed because the loss of fish wouldnt be significant o that thee is no inteest in the steam so stocking ates could be dopped At any ate not sending in the cad is a bit shotsighted o selfish as well as illegal Though its past the deadline the infomation on you last yeas salmon steelhead license is still impotant but its of no value unless you take a few minutes to send it in to the Wildlife Commission Do you eally cae?

ANATOMY OF A FISH Its Pats and What They Do by LARRY BISBEE Biologist Wam wate Game Fish adipose dosal fin anal fin caudal fin o tail vental pectoal Have you eve watched a fisheman cleaning his days catch when suddenly he stops and stats poking aound with the point of his knife and exclaims "I wonde what that little gadget is?" Chances ae he is looking at some unfamilia pat of the fishs anatomy that has attacted his attention To some people the anatomy of a fish is inteesting To othes it is a slimy mess not to be eckoned with and fo many it is something which has to be taken cae of while giving little thought to anything othe than getting the job done The anatomy of a fish can be inteesting if one stops and consides ^vhat function each pat plays in sup poting the life of the citte and bette adapting him to his paticula OREGON WILDLIFE aquatic habitat In geneal the stuctue of most fishes is quite simila with some exceptions and a wide vaiety of vaiations In spite of the many vaiations in shape the gound plan of body oganization in fishes is bilateal symmety as fo the vetebates geneally To simplify mattes the anatomy of a fish will be discussed only as it applies to the feshwate species with which we ae moe familia and with an occasional efeence to othe species The ideal fom of a fish is topedo shaped o fusifom and is designed pimaily fo speed and quick apid movement in wate Of all the fishes in the wold the tuna comes closest to esembling the ideal fom Fom this genealized shape the foms of many fish depat modeately to completely and ange fom globe shaped to thead like in outline The majoity of ou feshwate species like tout and salmon closely esemble the ideal shape while bass cappie flounde and catfish epesent moe exteme vaiations Movement of fish is dependent pimaily upon the fins o appendages attached to the body Poweful sweeps of the caudal o tail fin popel the body fowad at lighting speed Dosal pelvic pectoal and anal fins ae used somewhat fo locomotion but seve pimaily as stabilizing and maneuveing ogans to aid the fish in diving climbing banking tuning and stopping in wate A fatty adipose fin located between the dosal Page 3

Chances ae some faint vibations wee telegaphed fom you feet though the gound and into the wate whee they wee picked up by the sense ogans of the fish and sounded the alam Located along the mid line on eithe side of the body ae single ows of tiny poes extending fom the head to the tail This is the lateal line system of sense ogans found only in fish and the aquatic stages of amphibians The sense ogans ae pat of the nevous system and ae used to pick up vibations much too low fo the human ea to detect Most fish see though a pai of lidless eyes that ae much like ou own though modified fo vision unde wate Most often the eyes ae lateal on the head with patially independent fields of vision and movement Vaiations ange fom the blind cave fish which have no eyes to the flounde and othe flatfishes that have both eyes on one side of the head Heaing and balance as in highe vetebates is centeed in the inne ea In all fish the oute and middle ea ae missing leaving the inne ea as a specialized pat of the lateal line sensoy system A "swim bladde" o "ai bladde" is chaacteistic of tue fishes and is found in the body cavity usually lying ove the othe ogans found thee The ai bladde func Page 6 tions as a esonato in sound peception as a sound poduce as an accessoy beathing ogan and in weight egulating A good example is the ai bladde found in catfish The skeleton of a fish is a complex combination of extenal and intenal featues having both soft and had pats Most easily ecognizable is the so called axial fim skeleton composed of the skull the vetebal column the ibs and the intemuscula bones which give a fish its geneal shape The pelvic and pectoal gidles povide fim suppot fo the paied fins The extenal skeleton is less easily ecognized as such by the novice and is composed of scales fin ays and connective tissue that toughens the skin and joins it to undelying muscula tissue bone and catilage Like most othe vetebates muscle tissue makes up a good pat of the body Tunk muscles ae the most abundant and ae attached to the fim skeleton They ae pimaily used in movement of the skeletal pats and in locomotion To the aveage peson these muscles ae the "salmon steaks o fillets" which ae highly pized as food Unlike most vetebate muscle aangement the muscle tissue in fish is laid down in a schematic patten and appeas as neat stacks of flakes when the skin is emoved They give a fish consideable stength fo its size Most fish ae dependent upon thei aquatic habitat fo the life giving oxygen which they must have to suvive Catfish ae an exception and have the ability to absob oxygen though thei skin as well as though thei gills and fo this eason they can suvive fo seveal days out of wate povided thei bodies ae kept cool and moist To most othe fishes the ciculatoy system consisting of the gills the heat and the blood vessels is thei sole means of suvival The gills ae the lungs to a fish Exchange of cetain gaseous waste poducts fo fesh oxygen occus in the many delicate gill filaments attached to the ea edge of the moe idged gill aches A set of gills ae found on eithe side of the head in and at the ea of the mouth cavity whee wate ciculation is eadily available A stiff bony gill cove potects these delicate ogans fom outside damage Attached to the gills by a shot atey is the heat found lying in the foepat of the body cavity just below the gullet The heat of couse pumps the blood though a tubula netwok of ateies veins and capillaies A small ogan associated with the manufactue and destuction of blood cells is the spleen usually found at the ea end of the stomach The gound plan of the digestive tact of vetebates was established among fishes The ogans associated with this system lie in a continuous seies beginning at the mouth and ending at the anal opening just anteio to the anal fin and occupy the geate pat of the body cavity The ogans lying in between these two openings ae the mouth cavity the phaynx the gullet the stomach the pyloic caeca and the small and lage intestines The one ogan which puzzles the most people and ceates the most sti is the pyloic caeca attached to the intestines and lying just behind the live The pyloic caeca is a cluste of small finge like pouches that look vey much like a gob of woms at fist glance The caeca when pesent in fish has a digestive and /o an absoptive function A lage maoon coloed ogan occupying the font pat of the body cavity is the live which plays an impotant ole in the digestive pocess and also acts as a stoage place fo fats and blood suga Anothe ogan closely associated with the live is the gall bladde which acts as a tempoay stoage place fo live secetions Othe ogans in the digestive tact need little explanation since most ae easily ecognized The kidneys as most people ecognize them in mammals ae bean shaped ogans attached to the back wall of the body cavity In fishes these paied ogans take on a diffeent shape and can be ecognized as the long dak eddish bown pulpy mass lying just below the backbone Kidneys ae ichly supplied with blood vessels and ae quite bloody when boken in the pocess of emoving when cleaning fish fo the table They function mainly in the elimination of

EQ INDEX ON DOWNHILL SLIDE Ove the past five yeas US public inteest in the envionment has seemed to soa Catchwods such as "ecology" and "consevation" took on new meanings and became akin to those othe Ameican saced cows apple pie and mothehood Duing that peiod Congess committed fa moe money than eve befoe to clean up ou ai and wate a host of antipollution laws wee passed and an entiely new fedeal agency was even ceated to deal with them Communities and cities acoss the county have also taken steps to deal with thei own pollution poblems In fact has thee eally been an upswing in envionmental inteest and if so what has been its effect? What diffeence if any has it made in the quality of Ameican life? Has "mothehood gone out of the envionment" as some authoities have epoted? The Fifth Envionmental Quality Index thooughly examines the cuent status of the Ameican envionment in the Febuay Mach issue of NATIONAL WILDLIFE Magazine Published annually since 1969 by the National Wildlife Fedeation the EQ Index statistically and gaphically assesses whee we have been what we ae doing now and whee we ae headed in ou envionmental battle In putting ou cuent envionmental status into pespective the Index povides a concise analysis of a vaiety of envionmental data fom vaious govenment souces including the Envionmental Potection Agency Oveall the pictue shown by the Index is not bight with the total US envionment standing at 53 on a 100 point scale one point lowe than in 1973 "In too many lage cities the ai is still not fit to beathe" states the intoduction to the 1974 Index "and in too many pats of the county even the dinking wate is contaminated But pehaps most disconceting of all envionmentalism itself has become an inceasingly beleagueed movement" As indicative of the total US envionment seven key indicatos ae featued in the EQ Index: ai wate mineals wildlife living space Page 10 timbe and soil "All EQ indicatos except ai in fact ae down (fom pevious yeas)" accoding to the epot While the EQ measuements ae not exact the Index emphasizes they do epesent the best collective judgments of a National Wildlife Fedeation eseach team Besides poviding empiical documentation the EQ Index gives case examples of each of the indicatos Fo instance in the summay analysis of the status of US wildlife the Index epots that "Each yea in the US ove one million aces of habitat is eithe buied unde buildings and pavements o downed by esevois But in addition to obbing wildlife of vital living space ou industialized society kills outight as well Fo example moe than 150000 bids die annually in oil field sumps alone One ecent visit to a single oil sump evealed 187 victims 90 songbids 87 ducks one owl one eget five geese and thee heons Lagely because of habitat loss the Inteio Depatments endangeed species list has gone up fom 101 to 109 this last yea" A lack of public concen is epotedly not the pincipal poblem The Index quotes the latest annual epot of the Council on Envionmental Quality (CEQ) as stating "The nation has voted ovewhelmingly fo a cleane envionment" Instead the pincipal diagnosis of the poblem is a lack of funding Only about 1 pecent of the new Administation poposed $3044 billion budget is designated fo envionment and natual esouce pogams Accoding to the CEQ a total of $274 billion should be spent within the next decade by industy citizens and govenment in ode to meet fedeal pollution abatement standads by 1981 That includes not only ai and wate clean up but solid waste noise adiation and land eclamation as well While the $274 billion would only epesent 21/2 pecent of the nations goss national poduct any lowe level of spending wans the CEQ will "esult in even geate penalties in tems of health eceation o aesthetics" "At the pesent low level of spending" accoding to the Index "it will be impossible to each the CEQ goals" "The fact is" the NWF publication notes "that by cleaning up ai and wate pollution in the long un the nation will actually save money" As an example the Index obseves that by 1977 almost $2 billion in ai pollution damage will be saved if the pope contols ae put to use now If 1977 seems a long way off the annual epot points out "Conside the damage ai pollution alone is causing ight now: $16 billion pe yea o about $80 fo each Ameican in tems of damage to vegetation mateials popety and health" "In shot the clean up campaign has moved at little moe than a snails pace since it began back in 1955 with passage of the oiginal ai pollution contol legislation" The fifth EQ Index also documents changes in the degee of pollution fom the five majo ai pollutants and compaative clean up tack ecods of cities in diffeent egions of the county ove the past five yeas including an illustation of how the city of Chicago monitos its ai and wate pollution In an Index follow up the vetean envionmental specialist fo NEWSWEEK Magazine James Bishop examines the bizae and baffling "Politics of Pollution" "Despite some significant pogess on the clean up font" Bishop wites "the nations political and copoate leades though not necessaily the people themselves ae showing signs of pulling back fom the oot challenge pesented five yeas ago alteing the nations values of unlimited economic gowth and acknowledging that the pice of Ameicas pogess has been pohibitively high" Even though envionmental consideations ae now a basic pat of govenment decision making Bishop explains an inceasing tendency to cast envionmentalists into the scapegoat ole shows an "obliviousness to the fact that depletion of natual esouces sloppy mining pactices inefficient distibution wee some of the tigges of envionmental awaeness in the fist place" APRIL 1974
