ABSTRACT

Phytoplankton production, stand­ing stocks, and some relevant en­vironmental characteristics were forthe first time systematically mea­sured in the California Current sys­tem during the period from 1969through 1972. This work describesthe systems and methods of mea­surement, and presents the data ob­tained.

ABSTRACT

Data of the Florida portion of theBiology Phase of the CooperativeGulf of Mexico Estuarine Inventoryare recorded. They consist of thecatches made by seine, trawl, andplankton net at Chokoloskee in theTen Thousand Islands, Bokeelia inCharlotte Harbor, Maximo Point inTampa Bay, Atsena Otie Key nearCedar Key, and at the mouth of theSt. Marks River. Monthly sampleswere taken from April 1968 throughMarch 1969. Water temperature andsalinity at the times of sampling arerecorded.

ABSTRACT

Results .of a trawl survey ofgroundfish and crab resources oc­curring between Cape Spencer andUnimak Island, Alaska, are pre­sented. The survey was conductedby the International Pacific HalibutCommission during 1961-63; catchrecords from 1,272 stations were re­cently analyzed and prepared by theNorthwest Fisheries Center.

ABSTRACT

Hydrographic data were collectedfrom a natural marsh and a marshaltered by dredging, bulkheading,and filling in West Bay, Texas.Water samples were taken at 2-wkintervals during the day and night at10 stations from 25 March to 21 Oc­tober 1969. This report contains thelocation, depth, date, and time thesamples were taken and correspond­ing measurements of water tempera­ture, salinity, dissolved oxygen, dis­solved organic nitrogen, nitrite, totalphosphorus, inorganic phosphate­phosphorus, pH, carbon dioxide,total alkalinity, carbonate alkalinity,and turbidity.

Fishery Facts 7. Hipkins, Fred W."A Trapping System for HarvestingSablefish, Anoplopoma fimbria."November 1974,20 p., 17 figures.

ABSTRACT

An improved method of commer­cial fishing for sablefish, commonlyknown as black cod (not related to

the family of codfishes), is now usedby commercial fishermen fromCalifornia to Alaska. Fish are cap­tured and impounded in lightly con­structed, baited traps. The traps arecollapsible (they fold down) but arerigid when set out to fish. They canbe completely covered with webbingor steel wire mesh. Fish impoundedin the traps, which are attached togroundlines, are alive and in excel­lent condition when brought aboardthe fishing vessels. The traditionalsetline method for fishing sablefishrequires considerably more bait,larger fishing crews, and many morehours of work per day to catch acomparable amount of sablefish.

Details of the trapping gear, set­lines, and buoylines, plus the vesselequipment, fishing instructions, andlocations of traditional fishinggrounds are described.

ABSTRACT

The problem of sanitation infish processing plants is receivingincreasing attention from Federaland State regulatory agencies, aswell as private industry. This articlecovers recommended guidelinesthat can assist the processors offreshand frozen fish in evaluating their ex­isting sanitation practices or in estab­lishing new ones.

ABSTRACT

Artificial reefs provide or improverough bottom habi tat and offerfishery scientists and administratorsan effective technique to conserveand develop coastal fishery re­sources. With careful planning and

organized efforts, local reef commit­tees can build reefs to improvefishing and contribute to the recrea­tional and financial growth of coastalcommunities. Advice and proce­dures are presented for: I) selectingconstruction materials, 2) determin­ing a suitable reef site, 3) obtainingpermits, 4) buoying the reef, and 5)preparing, transporting, and placingreef-builing materials. Included inappendixes are instructions for pre­paring permits, addresses of Federaland State agencies involved in ap­proving or funding reefconstruction,and addresses of manufacturers ofmaterials and equipment.

NOAA Technical Report NMFSSS RF-68 I. "Physiological response ofthe cunner, Tautogolabrus adsper­sus, to cadmium." October 1974. 33 p.For sale by the Superintendent ofDocuments, U.S. Government Print­ing Office, Washington, DC 20402.

ABSTRACT

The cunner, Tautogo{abrusadsperslls, was exposed to six con­centrations of cadmium, as cadmiumchloride (CdCb ·2\12 H20), for 96 h.At the end of this exposure period,tests of blood serum osmolality andgill tissue oxygen consumption wereperformed. High levels (48 ppm) ofthis metal resulted in abnormallyhigh serum osmolality, and an ex­posure as low as 3 ppm reduced thenormal rate of oxygen consumption.Both of these parameters may be re­lated to observed tissue damage.

The histopathological effects ofacute exposure of the cunner tocadmium were manifested in thekidney, intestine, hemopoietic tis­sue, epidermis, and gill. Fewsignificant changes were noted in fishexposed to concentrations less than48 ppm. The results implicate renalfailure as the probable cause ofdeathsubsequent to acute exposure tocadmium.

Clearance of intracardially in­jected bacteria from the blood ofcunners exposed to 12 ppm cadmiumwas examined. The rate of bacterialuptake in the cells of the liver andspleen was increased, but the bacte­rial death rate within these cells wasdecreased. Exposure offish at 3 to 24ppm failed to influence antibodyproduction against sheet red bloodcells.

The activity of two liver enzymeschanged significantly with exposureto cadmium. Aspartate aminotrans­ferase was lower in the exposed fish,and a magnesium-linked oxidoreduc-

39

tase in exposed fish required 10 timesas much added magnesium to reachthe same level of activity as in thecontrol fish.

Chemical analyses were made foruptake and clearance of cadmiumfrom exposed cunners. In the uptakestudy, cadmium residues averaged8.5 times higher in liver than in gills.In the clearance study, substantialreductions in cadmium residueswere found in the gills and blood offish held in clean seawater for 6 wkafter exposure to cadmium, as com­pared to fish sacrificed immediatelyafter exposure. Muscle and carcasssamples from the "cleared" fishshowed little reductions in cadmiumlevels.

Sea Grant PublicationsReview Shrimp Diseasesand Fisheries Science

Shrimp diseases, an important factorin reducing natural populations and amajor consideration for mariculturists,is the topic of the new Texas A&MUniversity publication Handbook ofShrimp Diseases, by S. K. Johnson, fishdisease specialist for the Texas Agricul­tural Extension Service in the Depart­ment of Wildlife and Fisheries Science.Published by A&M's Sea Grant Pro­gram, the book contains detailed de­scriptions and illustrations of commonparasites of shrimp. It is intended as aguide for shrimp mariculturists, com­mercial fishermen, and others interest­ed in abnormal shrimp conditions. Sin­gle copies of the 20-page booklet areavailable free from the Sea Grant Col­lege Program, Texas A&M University,College Station, TX 77843. Requestpublication TAMU-SG-75-603.
