    Description: Just like other animals and humans, fishes are prone to diseases and predation. Diseases can be caused by one and/or combination of any of the following agents e.g. bacteria, fungi, viruses and parasites. Diseases have become a primary constraint to aquacultural development, which may affect the achievement of a desired impact for rapid development of fish culture in Nigeria. Apart from causing mortalities, they also cause loss of production quality, reduced growth, reduced fecundity, loss due to control measures and loss due to social factors associated with the farmer. This review has discussed the diseases that are associated with integrated fish farming including livestock cum fish farming, poultry-cum fish farming, Waste water fish farming, rice-cum fish farming e.t.c. The control of diseases associated with integrated fish farming requires a multi-disciplinary approach including chemotherapy, sanitation, routine hygiene, quarantine, genetic selection and immunoprophylaxis. The treatment and prevention of fish diseases follow the same principles used in chemotherapy of higher animals.

    Description: The shrimps were collected from three sampling sites: on the River Benue at Makurdi, Benue state, on the River Niger at Jebba and Lokoja and Idah at Kogi state from January to April, 2011. Macrobrachium felicinum and Atya gabonensis were sampled during this period, with Atya gabonensis occurring more abundantly. Condition factors of freshwater shrimps Atya gabonensis from the two water bodies in Nigeria range from 1.875for species in Jebba in March to 3.330 for Lokoja in March. The parameter ”b” of the length - weight relationship of the fresh water shrimps are less than three (rangingfrom 1.0233 for species from Lokoja in April to 2.7717 for species from Makurdi in Feburary). These values suggest negative allometric growth. The length frequency of freshwater shrimps sampled shows that peak populations of length groups occurred in April for species from Jebba and Makurdi while peaks occurred in January for species from Lokoja.Peak frequencies were observed in length of 4.0 - 5. 4cm and 8.5 - 9.9cm in January as well as 5.5 -6.9cm for species from Lokoja and in the group of 5.5 - 6.9cm in April for species from Makurdi and 7.0-8.4cm in April for both Makurdi and Jebba.
