Career opportunities for Animal and Environmental Biology students

Department of Animal and Environmental Biology, University of Port Harcourt, Nigeria
The department of Animal and Environmental Biology (formally known as Zoology) has 5 options each students choose from. The Options are as follows:

  1. Animal Health and Physiology
  2. Entomology
  3. Environmental Biology
  4. Fisheries and Hydrobiology
  5. Parasitology

Each of the aforementioned options are specialized in various aspects and have different career prospects. Let’s define each of the options and state some of their career opportunities.

Animal Health and Physiology

Animal Physiologists study important processes in the animal’s body and also deal with the functions of various parts in the body. The knowledge of Animal Physiologists can be applied to aid man in various aspects:

  • Work in Pharmaceutical companies. Drugs created are first tested on animals. Let’s say there’s a certain illness which man can transmit from rats. If a new drug is created to fight the disease, before tested on man, it’ll first be tested on rats. Animal physiologists carryout this experiment
  • Work as Toxinologists. Toxinologists are scientists who study the effects and control of venoms from animals, plants and microorganisms. They can (i) prepare anti-venoms (ii) provide emergency first-aid treatments (iii) prepare drugs from some venoms and lots more
  • Work with Veterinary surgeons
  • Breed Animals
  • Work with research institutes
  • Get higher degrees and become lecturers


This is the study of insects and other Arthropods. Entomologists can:

  • Work with the Ministry of Health (disease vector control unit) since there are posts for medical entomologists to provide pest control plans for different vectors-transmitted diseases (malaria, onchocerciasis, etc). They also monitor disease vectors and perform lots of tasks.
  • Work with the Ministry of Agriculture (pest control section) to help identify pests that attack crops and suggest control measures.
  • Grow and take care of bees for the production of honey (Apiculture)
  • Grow silkworms for the production of raw silk (Sericulture)
  • Produce pest controls
  • Work as a curator in a museum to identify and preserve insects
  • Get higher degrees and become lecturers

Environmental Biology

Environmental scientists record and measure features of the environment: study, access and develop methods of controlling or minimizing the harmful effects of human activities on the environment and develop conservation plans. Someone who studied Environmental Biology can:

  • Work as Environmental Health Officers helping to protect the public from diseases and related hazards. They ensure the safety of food and water, help control land, air and noise pollution and lots more
  • Work as Waste managers or Waste management consultants. They recycle wastes so their services are needed worldwide since recycling waste is better than burning or throwing them into the sea and better than producing new materials since recycling consumes less amount of energy
  • Work as Environmental technologists to collect information about the presence and control of pollutants in air, water and land.
  • Become consultants to the Government and other bodies to help solve the worldwide issue of global warming
  • Work in the Ministry of Environment to control the amount of wastes and pollutants disposed by man.
  • Work as consultants to Oil companies to help control the pollution of crude oil and chemicals in the soil and gases in the atmosphere.
  • Get higher degrees and become lecturers

Fisheries and Hydrobiology

Hydrobiology is the study of life in water. Hydrobiologists study different species of plants and animals that dwell in water. Zoologists who study fishes are known as Ichthyologists. Hydrobiologists can:

  • Work in the Ministry of Agriculture to help identify edible fishes and also identify endangered species of fishes.
  • Work in the Ministry of Water resources to help keep the waters clean and unpolluted so it can still be a suitable habitat for various organisms.
  • Work with Water Boards and River Basin authorities to analyze the chemical and organic components of drinking water
  • They can work in Fisheries organizations.
  • Work in various research institutes e.g. the institute of Oceanography and Marine research.
  • Work in oil companies as pollution consultants
  • Work as a curator in a museum to identify and preserve fish and other aquatic organisms
  • Get higher degrees and become lecturers


Parasitology is a branch of zoology that study parasites of man and animal. Parasitologists can:

  • Work with medical veterinary surgeons to identify parasites associated with man and animals respectively
  • Work in research institutes e.g. medical research institutes
  • Work in the Ministry of Agriculture to identify and control pests to livestock and crops
  • Work as a Public Health Management Consultant
  • Work in the ministry of Environment as consultants to the Environmental Impact Assessment
  • Get higher degrees and become lecturers

**Please note that the job opportunities of the various options aren’t limited to the aforementioned lists. There are lots more opportunities than the ones mentioned here.

The department of Animal and Environmental Biology has well equipped laboratories to conduct research with international standards and staffs who are Environmental Impact Assessment (EIA) experts and consultants to World bank, UNICEF, WHO and ministries (Health, Environment, Agriculture).

Entry requirements into Animal and Environmental Biology For B.Sc.

Admission is normally through Joint Matriculation Examination (JME) of the University Matriculation Examination (UME) and direct entry modes. The subject combinations required for this department in the University of Port Harcourt are specified in the Jamb brochure for the particular year the admission is sought.
The minimum requirements of the department for O level examinations like WAEC, GCE, NECO, etc. are credit passes in English language, Mathematics, Biology, Chemistry and Physics.

Graduate Programs in Animal and Environmental Biology

The department of Animals and Environmental Biology runs PGD, M.Sc. and Ph.D. programs in Animal Health and Physiology, Entomology and Pest Management, Environmental Parasitology, Fisheries and Hydrobiology.
