    Description: 1. Seahorses (Hippocampus spp.), many of which are listed as Vulnerable or Endangered on the IUCN Red List, are traded worldwide as souvenirs, aquarium fish and, primarily, for use in traditional medicines. Given concern over the sustainability of this trade, the genus was added to Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in May 2004. 2. This paper reports findings of the first ever survey of seahorse trade in Africa, conducted in Kenya and Tanzania in May and June 2000. 3. Seahorse trade in Kenya was found to be negligible, with approximately 10 live seahorses exported as aquarium fish annually. Until 1998, however, Kenya may have imported somewhere from 1 to 2.3 t of dried seahorses annually from Tanzania for re-export to Asian medicine markets. Seahorse trade in Tanzania remained substantial, with at least 630–930 kg of dried seahorse exported directly to Asia each year. 4. Accounts of declines in seahorse availability and seahorse size, although few in number, could be early warning signs that wild populations are suffering, at least locally. Close monitoring of future developments in the trade will be essential to allow for timely conservation action as and when necessary, and would contribute to our understanding of the ecological and economical implications of small-scale, non-food fisheries.

    Description: This paper examines the landings of three trawlers fishing the Ungwana Bay (Kenya) over a seven day period totalling about 200 hrs fishing time. A critical analysis is made of the catch and its composition in terms of marketable catch (target species and commercial fish) and bycatch (non-commercial, juveniles and debris). Prawns made up 13.7% of the catch while commercial fish amounted to 14.4% of the total. The remainder (71.9%) comprised of bycatch. Further breakdown showed that non-commercial fish made up the bulk of the by-catch with 42.9%. This group included Branchyura, Apogonidae, Leiognathidae, Squillidae and Gobiidae families. Juveniles accounted for 23.6% of the by-catch. The latter consisted for almost two-thirds of juveniles of commercial fish among which Ariidae were the commonest. Other families included Atherinidae and Carangidae. In the shallow 'Kipini' area, trawling does considerable damage to the benthic fauna and flora. The trawling attracts a large population of piscivorous birds creating artificial and unstable food webs. A Turtle Excluder Device (Anthony Weedless) was used on one of the trawlers but it appeared to result in lower catch of commercial fish allowing only small species and undersized fish into the cod end. It is concluded that the trawlers pose a threat to both the Ungwana fishery and other marine resources.
