Exotic Organisms: An Unsolved, Complex Problem

Mans interest in exotic organisms has a long history, some chapters of which have been recounted in fascinating detail by Laycock (1966). Mostly he told about purposeful introductions of game or food animals, showing how good intentions have sometimes led to disastrous results. Purposeful introductions (what we term biological management) are typically undertaken for mans benefit. The rationale most often

Range Expansion in Southern Florida of the Introduced Spotted Tilapia, with Comments on its Environmental Impress

The Spotted Tilapia, Tilapia mariae , apparently introduced to Dade County, Florida, between 1972 and 1974, has expanded its range dramatically. This exotic fish is now established in three counties (Broward, Collier, and Dade) in canals and lakes in an area encompassing approximately 2,000 km 2 .

Hybridization between Two Introduced, Substrate-Spawning Tilapias (Pisces: Cichlidae) in Florida

Three specimens from a mixed sample of introduced redbelly and spotted tilapias (Tilapia zilli and T. mariae, respectively) in Florida are interpreted as hybrids based on principal components analyses of variation in shape and meristics, intermediacy in jaw and pharyngeal dentitions and markings in the putative hybrids that combine patterns shown in the two parental species. Variability in discrimination among species and hybrids as a function of metric characters employed in principal components analyses argues for coverage of all aspects of shape in formulating character sets.

Range Expansion and Environmental Impress of the Introduced Walking Catfish in the United States

The Walking Catfish ( Clarias batrachus ), accidentally introduced into southeastern Florida in the mid-1960s, is currently distributed over more than 8,750 square km in ten counties of that State. The range of this exotic can reasonably be expected to extend over still further counties within the next few years. The present threat to fish farming interests, and the potential threat to native fishes, are thought to be serious.

Stock Enhancement in the Management of Freshwater Fisheries: A European Perspective

Abstract The European Inland Fisheries Advisory Commission (EIFAC), a regional commission of the Food and Agriculture Organization of the United Nations, convened a Symposium on Stock Enhancement in the Management of Freshwater Fisheries in conjunction with its 12th Session held at Budapest, Hungary, 29 May through 2 June 1982. The Symposium addressed the twin problems of introductions of exotic fishes and stockings of native fishes in an effort to define guidelines for both practices in European waters. These two specific aspects of stock manipulation were considered in seven sessions: 1) stocking with non-salmonids; 2) stocking with brown trout (Salmo trutta); 3) stocking with Atlantic salmon (Salmo salar); 4) introductions and transplantations-case histories and experience with some species; 5) introductions-overviews by country and the Lake Kinneret case; 6) ecological and practical aspects; and 7) conclusions and recommendations.

Dannie Alan Hensley (1944–2008)

O N 8 May 2008, DANNIE ALAN HENSLEY passed away from complications caused by respiratory failure at Hospital de la Concepción, San Germán, Puerto Rico. Dannie had been a faculty member at the University of Puerto Rico, Mayagüez, for 28 years where he served as Assistant Professor from 1980–1984, Associate Professor from 1984–1991, and was promoted to Full Professor in 1991. Dannie was born in Upland, California, on 24 October 1944. His father was a Colonel with the U.S. Air Force toward the end of World War II. As a result, Dannie moved in his earliest years to other locations that included Libya and, later, Japan. He made many young friends in Libya, and longed to return there for future visits. His father was later stationed at Edwards Air Force Base, California, and afterward in Hawaii. Dannie must have seen lots of ocean beneath him during those flights and wondered what lay below the surface. Dannie appeared to be a complex and private person to many he met for the first time. Those of us who were fortunate enough get to know and work with him discovered a wonderful person who was truly dedicated to the study of fishes. Add to this his dedication to make certain he had the format correct before submitting a manuscript to any journal. One can only wish that more authors shared this trait. In social circles when he felt relaxed, he had a sense of humor that never seemed to cease. His wide smile will never be forgotten by all that truly knew him. Dannie’s dry wit, acute observations of things natural (including people), and his broad knowledge of ichthyological matters endured him to many of us. One of us (RW) vividly recalls meeting Dannie for the first time at the first Indo-Pacific Fish Conference in Sydney, Australia (1981). On the postconference field trip to Lizard Island, Dannie asked rather puckishly why RW was madly photographing every different species of fish he could lay his hands on when ‘‘Jack Randall is doing that for all of us already.’’ The reply of ‘‘For ‘posteriority, since that fits my last name’’ was treated with hilarity by Dannie, and was the start of a treasured friendship, sharing jokes, beers, and the occasional intelligent conversation at many meetings thereafter. Dannie would phone Canada from Puerto Rico a couple of times a year just to chat for an hour or so. On a couple of occasions, he asked to borrow slides of flatfishes, and this was always the time to recap with nostalgic pleasure those early days at Lizard. He often called Victor G. Springer at the Natural History Museum in Washington, D.C., to discuss matters regarding procedures with his taxonomic work. Dannie began his higher education at San Bernardino Valley College, a community college, where he completed his first two years of higher education. He took a year off at Wake Island, North Pacific Ocean, prior to graduating with honors in 1966. That was a very formative year for Dannie’s future that resulted in his first publication in 1965. Dannie subsequently enrolled at California State University, Fullerton, where he and his advisor, David W. Greenfield (only four years older than Dannie), had two papers (one with other authors) published in Copeia in 1970. During his years at Fullerton, he and Dave Greenfield drove into Mexico with other graduate students (Jim Wiley and Steve Ross) to collect fishes for a paper published in Copeia in 1970. Dave Greenfield said that Dannie knew he wanted to be an ichthyologist. Dannie also served as a teaching assistant and, for one summer, as a field ecologist with the University of California, Los Angeles. From 1974 through 1978, Dannie was an ichthyologist with the Marine Research Laboratory of the Florida Department of Natural Resources, now a division of the Florida Fish and Wildlife Conservation Commission, in St. Petersburg. For much of that time, he studied toward his Ph.D. at the University of South Florida under John C. (Jack) Briggs’ guidance. Before and during that part of his life, he also served as an instructor teaching biology and other sciences at several central-west Florida regional middle and high schools, Hillsborough Community College, and University of Tampa at their MacDill Extension on the U.S. Air Force Base. Derril Moody, who later became another graduate student of Jack Briggs, was teaching seventh grade at a local school and contacted Dannie and asked him to identify a fish that one of his students had caught in the Little Manatee River. To quote Derril (pers. comm., 2008), when Dannie arrived to examine the fish, ‘‘He wasn’t exactly what I expected. Here was this short guy, red beard, red hair, balding, glasses, and of slender build.’’ The fish was an introduced species, Hoplias malabaricus, with many specimens subsequently captured prior to its demise in Florida as result of the winter freeze of 1977. Later, they both worked together as biologists with the Florida Department of Natural Resources Marine
