NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on \arun:s phases o( the industry. The NOAA Technical Report NMFS Circular series continues a series that has been in existence since 1941. The Circulars are technical publications of general interest intended to aid conservation and management. Publications that review in considerable detail and at a high technical level certain broad areas of research appear in this series. Technical papers originating in economics studies and from management in- vestigations appear in the Circular series. NOAA Technical Report NMFS Circulars are available free in limited numbers to governmental agencies, both Federal and State. They are also available in exchange for other scientific and technical publications in the marine sciences. Individual copies may be obtained (unless otherwise noted) from D825.

Frank, Administrator National Marine Fisheries Service FOREWORD This issue of the "Circulars" is part of subseries entitled "Marine Flora and Fauna of the Northeastern United States." This subseries will consist of original, illustrated, modern manuals on the identification, classification, and general biology of the estuarine and coastal marine plants and animals of the North- eastern United States. Manuals will be published at irregular intervals on as many taxa of the region as there are specialists available to collaborate in their preparation. The manuals are an outgrowth of the widely used "Keys to Marine Invertebrates of the Woods Hole Region," edited by R. I. Smith, published in 1964, and produced under the auspieces of the Systematics- Ecology Program, Marine Biological Laboratory, Woods Hole, Mass. Instead of revising the "Woods Hole Keys." the staff of the Systematics-Ecology Program decided to expand the geographic coverage and bathy- metric range and produce the keys in an entirely new set of expanded publications. The "Marine Flora and Fauna of the Northeastern United States" is being prepared in collaboration with systematic specialists in the United States and abroad. Each manual will be based primarily on recent and ongoing revisionary systematic research and a fresh examination of the plants and animals. Each major taxon, treated in a separate manual, will include an introduction, illustrated glossary, uniform originally il- lustrated keys, annotated check list with information when available on distribution, habitat, life history, and related biology, references to the major literature of the group, and a systematic index. These manuals are intended for use by biology students, biologists, biological oceanographers, informed laymen, and others wishing to identify coastal organisms for this region. In many instances the manuals will serve as a guide to additional information about the species or the group. Geographic coverage of the "Marine Flora and Fauna of the Northeastern United States" is planned to include organisms from the headwaters of estuaries seaward to approximately the 200-m depth on the con- tinental shelf from Maine to Virginia, but may vary somewhat with each major taxon and the interests of col- laborators. Whenever possible representative specimens dealt with in the manuals will be deposited in the reference collections of major museums in the region. After a sufficient number of manuals of related taxonomic groups have been published, the manuals will be revised, grouped, and issued as special volumes. These volumes will thus consist of compilations of in- dividual manuals within phyla such as the Cnidaria, Arthropoda, and Mollusca, or of groups of phyla.

HI Marine Flora and Fauna of the Northeastern United States. Copepoda: Cyclopoids Parasitic on Fishes JU-SHEYHO 1 ABSTRACT This manual includes an introduction on the general biology, an illustrated key, an annotated sys- tematic list, a selected bibliography, and an index to the 19 species of cyclopoid copepods parasitic on marine fishes of the northeastern United States. INTRODUCTION The "Order Cyclopidea" as defined by Yamaguti (1963) consists of four families of copepods parasitic on both freshwater and marine fishes. They are Bomo- lichidae, Ergasilidae, Grandiunguidae, and Tuccidae. However, according to Sproston et al. (1950), Ho (1967b, 1970, 1971a), Izawa (1973), and Cressey (1975), the Order should include six more families: Lernaeidae, Tel- sidae, Chondracanthidae, Pharodidae, Philichthyidae, and Shiinoidae; and the family Bomolichidae should be separated into the Bomolochidae and Taeniacanthidae. The family Grandiunguidae was created by Yamaguti (1963) to accommodate a single species of copepod, Grandiungus promicrops Pearse 1952. 1 have checked the type-specimen of this species deposited in the National Museum of Natural History in Washington, D.C., and have discovered that it is merely a chalimus larva of a lernaeocerid copepod detached from its frontal filament. Therefore, the family Grandiunguidae together with its monotypic genus and species, Grandiungus promicrops, should be discarded. Consequently, the "Order Cy- clopidea" as it now stands consists of ten families, name- ly, Bomolochidae, Chondracanthidae, Ergasilidae, Ler- naeidae, Pharodidae, Philichthyidae, Shiinoidae, Taeniacanthidae, Telsidae, and Tuccidae. The lernaeids are exclusively parasitic on freshwater fishes and the ergasilids are predominently parasites of freshwater fishes, except a few species that are found on fishes of brackish or coastal waters. The members of the other eight families are strictly marine parasites. Cyclopoid copepods on fishes are found on the body surface or in the oral cavity, gill cavity, nasal cavity, and cephalic canal. They attach to the host by hooking their modified, prehensile second antennae (Ergasilidae, Chondracanthidae, Pharodidae, Tuccidae), maxillae (Telsidae), or maxillipeds (Bomolochidae, Shiinoidae, Taeniacanthidae); by burrowing their anchorlike 'Department of Biology. California State University, Long Beach, CA 90840. modified cephalothorax (Lernaeidae); or by boring into and lying free inside the cephalic canal of the host's gill operculum and head (Philichthyidae). Our knowledge of the biology of this group of parasites is still scanty. A complete life cycle is known of only some freshwater species. Some sporadic reports on the larval stages are available for a few marine species. However, based on the existing information, it seems that the parasitic cyclopoids do not require an intermediate host. The nauplius hatched from the egg develops into the copepodid larva, which is the infective stage and searches for the new host. Usually, there are five copepodid stages and mating takes place right after the female finishes its last molt in the larval stage. The male dies after mating, but occasionally it is found holding to the genital segment of the ovigerous female (Bomolochi- dae, Shiinoidae, Taeniacanthidae, Telsidae) or lying in the host's cephalic canal with the mature female (Philichthyidae). However, in the family Chondra- canthidae, the male is characteristically a symbiont of the female; it is a dwarf (Fig. 1) and holds on to one of the two vermiform processes on the female trunk near the genital somite. Therefore, adult cyclopoids found at- tached to fishes are all female. The mature females of the families Chondracanthidae, Lernaeidae, Pharodidae, Philichthyidae, Shiinoidae, and Tuccidae are highly transformed and do not appear as a typical cyclopoid (Fig. 2). In these modified copepods an extensive but gradual modification of the body occurs in the process of maturation after the last molt in the copepodid stage. While all the cephalic and oral appendages are retain- ed with certain degree of modification in the adult female, the thoracic appendages of the parasitic cy- clopoids exhibit a wide spectrum of variation. While the maxillipeds are lacking in some families (Ergasilidae, Philichthyidae, Shiinoidae), the remaining thoracic appendages vary from the typical unmodified cyclopoid thoracopods (Ergasilidae, Lernaeidae) through the par- tially (Bomolochidae, Taeniacanthidae, Telsidae, Tuc- cidae) or completely (Chondracanthidae, Pharodidae, Philichthyidae) modified legs to the absence of the legs entirely (Chondracanthidae, Philichthyidae).

However, only 19 species belonging to six families are so far known to occur within the range covered by this manual (from Maine to Virginia). Since only a small fraction of fishes occurring off the coast of northeastern United States have ever been examined for the copepod parasites, certainly many more species of parasitic cyclopoids are yet to be discovered. It is well known that a freshwater fish heavily infested with cyclopoids, particularly with those of the genera Ergasilus and Lernaea, often dies. Although no such reports have ever been made on marine fishes, a fish kill due to heavy infestation of marine cyclopoid copepods cannot be ruled out, because loss of weight and retarda- tion of the rate of growth of the fish under the influence of parasitism is known. In collecting specimens of parasitic cyclopoids, one must be very careful not to damage the attachment ap- paratus of the parasite, for, in many cases, this modified appendage carries important taxonomic information. Removal of the parasite from the host is preferably done under a dissecting microscope, but, if the removal must be done in the field, a generous amount of the host tissue must be taken together with the parasite. The parasite is subsequently removed from the collected host's tissue under a dissecting microscope in the laboratory. The collected specimens are preserved and stored in 70% al- cohol. The study of their external anatomy always re- quires dissection of the appendages. This can be done first by soaking the specimen in lactic acid for several hours and then removing the appendages under a dis- secting microscope with a pair of sharp needles. The appendages removed are studied under a compound microscope. KEY TO THE MARINE CYCLOPOID COPEPODS PARASITIC ON FISHES OF THE NORTHEASTERN UNITED STATES The following key is constructed for the female cyclo- poids that have been reported parasitic on marine fishes from Maine to Virginia. A separate key to the male is not given because some of them are unknown and the others, ANTENNULE Figure 2. — Holobomolochus albidus; dorsal view, showing structures and terms used in key. PROSOME LEG I LEG 2 LEG 3 LEG 4 LEG 5 GENITAL SEGMENT CAUDAL RAMUS UROSOME when they occur, are always in close association with their female partners. Although 19 species of cyclopoids are known from the northeastern United States, the following key is prepared for identification of the 11 species of Chondracanthidae, one species of Philichthyidae, and one species of Tuc- cidae. Identification of the remaining three species of Bomolochidae, two species of Ergasilidae, and one species of Taeniacanthidae is not provided because these families are relatively large and very poorly known from the region. If a key to the few known species is provided, it might lead a user to misidentify an unreported species as one listed in the key. 1 Body typical copepod form (Fig. 2) 2 1 Body modified, not copepod form (Fig. 1) 4 3 2(1) Antenna with single terminal claw (Fig. 3) , Ergasilidae 2(1) Antenna hearing several terminal setae and claws (Fig. 4) 3 Figure 3. — Ergacilus labracis; antenna.

The Board, which established the format for the "Marine Flora and Fauna of the Northeastern United States," invites systematists to collaborate in the preparation of manuals, re- views manuscripts, and advises the Scientific Editor of the National Marine Fisheries Service. All illustrations were made from the collections in the Divi- sion of Crustacea, National Museum of Natural History, Smith- sonion Institution, Washington, D.C. Melbourne R. Carriker, Bruce C. Coull, Roger F. Cressey, and Arthur G. Humes criti- cally read the manuscript. COORDINATING EDITOR'S COMMENTS Publication of the "Marine Flora and Fauna of the North- eastern United States" is most timely in view of the growing un- iversal emphasis on environmental work and the urgent need for more precise and complete identification of coastal organisms than has been available. It is mandatory, wherever possible, that organisms be identified accurately to species. Accurate scientific names unlock the great quantities of biological infor- mation stored in libraries, obviate duplication of research al- ready done, and often make possible prediction of attributes of organisms that have been inadequately studied. Ju-shey Ho began his study of the systematics of the parasitic Copepoda in 1960 when he was a teaching assistant at the Department of Zoology. National Taiwan University, Taipei, Taiwan. In 1962 he went to Boston University to pursue graduate studies on the copepod parasites of marine animals. Ho joined the faculty of California State University, Long Beach, in 1970 where he has continued his research on parasitic Copepoda. His studies have resulted in more than 50 papers on the systematics of marine parasitic copepods, including a monographic revision of Chondracanthidae at the generic level. Currently he is working on a series of copepod parasites from the fishes of the Great Barrier Reef, Australia. Preparation of this manual was supported in part by a grant from the Environmental Protection Agency to the Editorial Board of the "Marine Flora and Fauna of the Northeastern United States." Work on the "Marine Flora and Fauna of the Northeastern United States" by the Coordinating Editor is sup- ported by the College of Marine Studies, University of Dela- ware.

The mission responsibilities of NOAA are to monitor and predict the state of the solid Earth, the oceans and their living resources, the atmosphere, and the space environment of the Earth, and to assess the socioeconomic impact of natural and technological changes in the environment. The six Major Line Components of NOAA regularly produce various types of scientific and technical infor- mation in the following kinds of publications: PROFESSIONAL PAPERS— Important definitive research results, major techniques, and special in- vestigations. TECHNICAL REPORTS— Journal quality with extensive details, mathematical developments, or data listings. TECHNICAL MEMORANDUMS— Reports of preliminary, partial, or negative research or tech- nology results, interim instructions, and the like. CONTRACT AND GRANT REPORTS— Reports prepared by contractors or grantees under NOAA sponsoiship. TECHNICAL SERVICE PUBLICATIONS— These are publications containing data, observations, instructions, etc. A partial listing: Data serials: Pre- diction and outlook periodicals; Technical manuals, training papers, planning reports, and information serials; and Miscellaneous technical publications. ATLAS — Analysed data generally presented in the form of maps showing distribution of rainfall, chemical and physical conditions of oceans and at- mosphere, distribution of fishes and marine mam- mals, ionospheric conditions, etc. Information on availability of NOAA publications can be obtained from: ENVIRONMENTAL SCIENCE INFORMATION CENTER ENVIRONMENTAL DATA SERVICE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION U.S. DEPARTMENT OF COMMERCE 3300 Whitehaven Street, N.W.
