    Description: National Workshop on Small-scale Fisheries, Cyclone Ockhi and Disaster Risk Management was held on 28 to 29 May, 2018 at Thiruvananthapuram. The workshop was organised by the International Collective in Support of Fishworkers (ICSF) Trust with the support of the Food and Agriculture Organization of the United Nations (FAO). The workshop was attended by a large number of distinguished participants, including fishworker organisations, government officials, academics, non-governmental organisations, civil society organisations and the disaster affected community. Representatives from FAO and the Bay of Bengal Programme Inter-Governmental Organisation (BOBP-IGO) also attended the programme. On 29 November 2017, a deep depression, detected in the Indian Ocean southwest of Sri Lanka, rapidly intensified into a cyclonic storm off the coast of Tamil Nadu and Kerala and the Union Territory of Lakshadweep Islands. Cyclone Ockhi, as it was named, took the life of a number of fishers, injured many and destroyed fishing vessels and gear.

    Description: Between 29 November and 3 December, 2017, Cyclone Ockhi devastated hundreds of lives and livelihoods of coastal fishing communities in Kerala and Tamil Nadu, India. This study assesses the impacts of the cyclone on fishing communities and the mechanisms in place at the local, national and international levels to address disaster risks and sea safety in small-scale fisheries, using a human rights-based approach. In line with the Sendai Framework 2015-2030 and the Voluntary Guidelines for Securing Sustainable Small-scale Fisheries, the study recommends applying “relief-development continuum” and “build back better” concepts to the management of disaster risks in order to save lives and to reduce damage to fisheries assets and livelihoods.

    Description: The kilishi of Heterotis niloticus was produced for determination of appropriate slurry formulations for fish kilishi preparation. Thirty six freshly caught samples of H. niloticus with average weight of 306.20 ~c 18.33g, kilishi of this species was prepared with three different slurry formulations of high (F1), medium (F2) and low (F3) proportions of groundnut dough to spice mixture in the ratio of 1.3: 1.0, 1.0: 1.2 and 1.0: 1.8, respectively. Results of proximate composition indicated that kilishi of the H. niloticus prepared with formulation 3 (F3) recorded significantly higher (p〈0.05) protein content (54.22 ~c 0.01 %) and lower lipid content (8.00 ~c 0.00%), despite recording significantly higher (p〈0.05) moisture content (9.93 ~c 0.07%). Sensory score of kilishi of H. niloticus processed with F3 formulation rated significantly higher (p〈0.05) for taste, flavour and general acceptability with mean scores of 5.94 ~c 0.21,5.77 ~c 0.20 and 5.50 ~c 0.22, respectively. It could be concluded that kilishi of H. niloticus prepared with F3 formulation was the most acceptable hence, recommended for use in kilishi production.

    Description: Biotechnology per se is not a panacea for the world's problems of hunger and poverty. However, genetic engineering in particular, offers outstanding potentials to increase the efficiency of animal improvement. Thus, biotechnology could enhance global food production and availability in a sustainable way. Case studies from Egypt and India also demonstrate that highly immune genetically modified fishes, transgenic fishes, chromosome engineering and gene banking are very appropriate for fish farmers and consumers in developing countries. As the entire technology can be packaged into the germ cells of fish, it can easily be integrated into traditional small-holder fish farming systems. Except for a few innovative transfer projects, though, the application of biotechnology until now remains concentrated in the industrialized world. Combined with insufficient own scientific and regulatory capacities, the increasing privatization of international aquacultural and fisheries research and the strengthening of intellectual property rights complicate the access of developing countries to biotechnology. Profound constitutional adjustments are therefore essential to ensure that biotechnology does not bypass the poor.

    Description: The microbial load of four different fish species from five different market locations in Ibadan metropolis were determined using standard microbiological procedures. The bacteria count of fish sampled from Ojo market was the highest while the bacteria count of the fish sample from Bodija market was the lowest. There was no significant difference (p〈0.05) in the microbial load of the fish sampled from various market locations in Ibadan metropolis. Similarly, there was no significant difference (p〉0.05) in the microbial load on various fish species sold in Ibadan metropolis. The isolated bacteria from the study were: E. coli, Salmonella spp, Klebsiella spp, Staphylococcus aureus, Aerosomonas spp, Pseudomonas spp, Vibrio spp, Serratia spp, Chromobacterium spp, Enterobacteria spp and Shigella spp. The fungi count of fish sampled from Omi markets was the highest while the fungi count of the fish sampled from Ojo market was the lowest. The following fungi were however isolated from the study: Aspergillus flavus, Penicillium spp, Fusarium oxysporum, Trrichoderma spp and Ceotrichium albidium. The study shows that reheating may be necessary to destroy or inactivate micro-organisms in smoked fish before consumption.

    Description: An investigation was conducted on the morphometric features and proximate body composition of rocky freshwater prawn, Caridina africana occurring at Erin-Ijesa Waterfalls in Osun State, Nigeria. The adult prawns were collected at the first layer of the Waterfalls using scoop nets and locally fabricated sieves because of the shallow nature of the water body and tiny size of the species. Morphometric features were measured using measuring board and Vernier calipers while the proximate analysis was determined by atomic absorption spectrophotometry in the laboratory. The morphometric variables placed the species correctly into the Infra order Caridea and family Atyidae because the first and second chelipeds were shorter than the remaining three pairs of walking legs. Male prawns were significantly bigger (p〈0.05). than the females as revealed in the morphometric features. The proximate analysis showed that C. africana is composed of 58.79% protein, 5.42% lipid, 11.56% carbohydrate, 14.7% ash and 0.21 % crude fibre. The micro-nutrient composition included iron, zinc, copper, nickel and cadmium. The values for these nutrients make the study to suggest that C. africana could be a nutritive food bio-material for humans and other livestock nutrition especially the fin-fish aquaculture programme.

    Description: We studied the trophic attributes of the toadfish, Batrachoides liberiensis off the Qua Iboe River estuary Nigeria, between August 2008 and July 2009. The fish species has no well defined stomach; the intestine was used as gut. Gut contents analysis of 360 specimens of the toad fish revealed that 11 food items (Penaeus notialis, Sersama alberti, crayfish remains, unid fish, fish bones, fish remains, unid gastropod, insect remains unid clam and sand grains)] were ingested. The food items were re-assigned into 6 major ecological categories based on food ponderal index (%FPI): Pisces (FPI= 35.33%), Crustacea (FPI= 20.73%), unid Gastropoda (FPI=14.32%), Mollusca (FPI= 12.48%), Insecta (FPI= 11.64%) and FPI of 5.50% sand grains. Males were significantly higher in feeding intensity (Average gut fullness, AGF: t = 2.083, 358 df, P〈0.05) vis-a-vis the females. There were similarity in rank-order of the seasonal dietaries (spearman-rank correlation: rs = 0.871, P〈0.02). Sex ratio was male-biased. B. liberiensis in the Qua Iboe estuary is carnivorous, exhibiting affinity to piscine as major dietaries.

    Description: The effect of zinc exposure evaluated during a four day exposure periods at 13.88ppm, 26.75ppm, 53.5ppm,107ppm and 214ppm to Clarias gariepinus sub-adults showed the 96h LC50 as 26.62ppm. The threshold value was 20.30ppm. The muscle of the exposed fish analyzed showed a significant decrease in all the major cations and anions (Na+, CL-, Ca2+ K+, Mg2+) at (p〈0.05). The research revealed that there was no total inhibition of uptake of the cations and anions and also that uptake of these metals, that is cations and anions (Na+,-CL-, Ca2+ K+, Mg2+) increased rapidly during the 24 hours and dropped at 48 hours and 72 hours and gradually increased at the end of 96 hours showing that it was time dependent. During exposure period, affected fish stood in upright position with their snouts above the water surface, gasping for air. Observation of the exposed fish showed that they were peeling of skin, increase in opercula movement, erratic swimming, quietness and finally death. This research therefore recommends that zinc should be applied appropriately at 26.30ppm to avoid death of fish, man and other aquatic organisms that are the chief consumer.
