EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment).

Life- history traits of Chloroscombrus chrysurus (Actinopterygii: Perciformes: Carangidae) in tropical waters of the Atlantic Ocean. Acta Ichthyol. Piscat. 48 (1): 1–8. Background. In fishery biology, information on life-history traits is extremely useful for species conservation and the monitoring, management and sustaining of fish stocks. Nevertheless, detailed biological information is very limited for tropical fishes, especially for those with low economic value, such as the Atlantic bumper, Chloroscombrus chrysurus (Linnaeus, 1766). This species is commonly captured by artisanal fisheries in tropical waters and the lack of information makes difficult the development of strategies for the proper management of the species. Therefore, the presently reported study intended to provide new data on the biological parameters of C. chrysurus to fill the gap in the existing knowledge. Materials and methods. Life-history traits of the Atlantic bumper, C. chrysurus, were estimated from 335 fish collected in a western Atlantic region during fishery surveys carried out between 2010 and 2012.

  • Guide to the Coastal Marine Fishes of California
    STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft.

All fish were measured, preserved and identified as post flexion larvae and early juvenile of Chloroscombrus orqueta, Hemicaranx leucurus and Caranx caballus. C. orqueta stood out in frequency and abundance. H. leucurus were found only in autumn, while the others were present in different seasons. This is the first time recordingH. leucurus and C. caballus associating with cannonball jellyfish. Further studies must evaluate this association as all fish caught were at vulnerable stages, and must be considered in jellyfish fishery management.

  • Literature EVALUATING GEAR and FACTORS AFFECTING CATCH
    Literature EVALUATING GEAR AND FACTORS AFFECTING CATCH AND SAMPLING VARIATION Frank J. Schwartz Patricia A. Howland Special Scientific Report for .Carolina Power and Light Company Raleigh, North Carolina 1 June 1978 Institute of . Marine Sciences University of North Carolina Morehead City, North Carolina 28557 INTRODUCTION Scientists are always concerned with the data they obtain. This may be in the form of: did I sample enough, was the sample size large enough to be con- sidered representative, did I sample all habitats, faunas, etc., did I take the proper environmental data, and should I sample only during the day or night hours. These and a host of questions besiege him in his quest for representa- tive and precise information about the area or fauna being studied. These concerns are often unknowingly upset by ignoring factors other than biological that may seriously alter the results and conclusions reached. These may be subtle factors such as: how efficient is the gear used, how ef- fective is its operation, is it selective for certain sizes or species of organisms because of color or strength of material. While the organisms may behave one way in relation to the gear, how does the behavior of the gear affect the po- tentially capturable organism? What type of gear should be used--midwater or other? Will mesh size affect the results? Does one type of gear sample a species, population or area better than another and why? What effect does human fatigue have on gear operation? Even with awareness of these and many other factors that influence the outcome of a research study, extraneous factors beyond our control may fur- ther influence the observed data.
