- Description: The combined fish collection databases of the Albany Museum and the J.l.B. Smith Institute of Ichthyology are used to identify hotspots of endemism and threatened fish distributions in South Africa. Hotspots of fish species richness occur in the north-eastern lowveld sectors of South Africa and along the ecotone between the tropical/ subtropical and temperate faunal zones. Hotspots of endemic fish richness occur within both the tropical and temperate faunal regions, notably in the Olifants River system, Western Cape and in areas of high relief such as the Cape Fold Mountains, the Amatola-Winterberg (Eastern Cape), and the Drakensberg Escarpment (Kwazulu/ Natal-Eastern Transvaal). Threatened taxa are concentrated in the hotspots of endemic species richness which coincide largely with areas of major river conservation concern. There is limited scope for fish conservation within the ambit of formal (or informal) declared reserves, and the survival of the fauna depends on the success of river catchment conservation management. The value of museum collections in identifying areas of conservation concern for freshwater fishes is emphasized, and highlights the importance of well-preserved voucher specimens for biodiversity conservation.

- Description: The Kowie and Great Fish estuaries are situated less than 30 km apart, yet they differ considerably in terms of riverine inflow, turbidity, food resources and habitat availability. The ichthyofauna of the two estuaries were sampled using plankton, seine and gill nets. A greater ichthyofaunal richness (R) was recorded in the Kowie estuary and this is attributed to the wider range of habitats and greater degree of marine influence in this system. In contrast, all three sampling gears revealed an approximate 3:1 ratio between fish abundance in the Great Fish and Kowie estuaries.

- Description: On 27 October 1994 we met at the Good Hope Centre with the purpose of launching a process for developing a fisheries policy. The call of the meeting was driven by the problems and the situation faced by Fisher folk. Communities in the coastal areas are starving and living under bad conditions. These resources are not utilised to address these problems at present as stated in the RDP. The present system creates conflict between individuals and between regions. Since the appointment of Mandla Gxanyana at the Good hope centre meeting lots of things have happened, consultation with regions, forums, organisation and individuals on how to take up this process and the formation of the committee. There was final agreement of bottom up approach. This approach encouraged region like Eastern Cape to take up the process and reported into the siting of the legislature of the Eastern Cape region. In KwaZulu Natal process of creating forum have started which include all the players. I hope this process will create a national Fishing Forum, which shall have committee in the different coastal communities, because RDP outline how our resource should be managed, that our communities are great pillar for the management of our resources.

- Description: During the past few months, we experienced the mass mobilisation of 70 000 teachers, nationally. This collective showing of unity and strength forced the State to listen to the grievances of teachers. In the Western Cape, militant teachers took to the streets to picket, held successful sit-ins at Regional Offices, participated in mass marches and rallies. We saw unprecedented mass mobilisation of teachers on three occasions. Firstly, a SADTU meeting at the Athlone Civic Centre where a resolution was adopted to intensify ttie campaign against unilateral restructuring and retrenchments. Secondly, after consultations with other teacher organisations in the Western Cape, we embarked on an ‘ambitious’ plan of uniting all organisations against rationalisation, merit awards and our fight for a Living Wage. This culminated in the historic meeting at the Good Hope Centre which drew approx. 10 000 teachers together to demonstrate the anger of teachers at the racist education departments and the intransigent State. Thirdly, The Western Cape Region of SADTU supported the call by National to suspend the strike regarding the Living Wage demand but agreed to continue with strike action, 24 25 May, around the issue of rationalisation and retrenchments. This was in accordance with SADTU National position. On the 26 May, at a SADTU mass rally at the Athlone Stadium, (psst! the Civic Centre was too small !) approx. 9 000 teachers, from as far as Bredasdorp, Swellendam, Ceres, Tulbagh, Vredendal, Malmesbury and Atlantis braved the inclement weather to hear a report-back from our comrade chairperson, Vivienne Carelse who was part of the SADTU National Negotiating Team with the Department of National Education

- Description: Pairs of Palewinged Starlings associate throughout the year and roost at the nest sites. Flock sizes are generally small, even during the non-breeding season. Allofeeding and allopreening have not been recorded. Wing displays emphasize the white region of the primaries. The territory appears to be restricted to the nest site. Interspecific aggression occurred between Redwinged and Palewinged Starlings, and was also directed at other Ed species frequenting the cliff. A form of ceremonial gathering occurs re in Palewinged Starlings. A review of the literature suggests that on behavioural grounds the Palewinged Starling shows no close affinity to the Redwinged Starfng or to any other member of the genus.

- Description: The Rooi Rand dyke swarm is approximately 200km long and up to 20km wide. It crops out in the southern portion of the Lebombo monocline where the dykes intrude basalts of the Sabie River Basalt Formation which is the major basaltic unit in the eastern portion of the Karoo volcanic succession. The Horingbaai dolerites form thin dykes and sills which intrude the base of the Etendeka lava pile (considered part of the Karoo Volcanics, but correlated with the Serra Geral Formation of Brazil) along the coast of Namibia. Both the Rooi Rand and Horingbaai magma types are similar in composition to enriched MORB and are compositionally distinct from most of the Karoo-basalts they intrude.

- Description: [From the introduction]: Horses played a major role in the transport system in Britain until, in the years following the conclusion of the First World War, they were gradually ousted by motor vehicles. In 1917, when the first reasonably complete equine census of Britain was undertaken, there were 2,650,773 horses in the country, 1,115,920 of which were used for agricultural purposes (Chivers, 1976). Horse breeding was therefore of great importance and a variety of attempts was made to improve the quality of horses by subsidising stallions that travelled the countryside during the breeding season, and that were available, at a fee, for the service of mares. This paper describes some of the routes followed by stallions that formerly travelled in Brycheiniog and adjacent counties.

- Description: [From the introduction]: Horses played a major role in the transport system in Britain until, in the years following the conclusion of the First World War, they were gradually ousted by motor vehicles. In 1917, when the first reasonably complete equine census of Britain was undertaken, there were 2,650,773 horses in the country, 1,115,920 of which were used for agricultural purposes (Chivers, 1976). Horse breeding was therefore of great importance and a variety of attempts was made to improve the quality of horses by subsidising stallions that travelled the countryside during the breeding season, and that were available, at a fee, for the service of mares. This paper describes some of the routes followed by stallions that formerly travelled in Brycheiniog and adjacent counties.

- Description: A simple, sensitive and reliable high-performance liquid chromatographic procedure has been developed for the determination of erythromycin in human serum and urine using amperometric detection. A solid-phase extraction procedure was used followed by chromatography on a reverse-phase column. The mean recovery of erythromycin from serum and urine was 80%. This method allows both erythromycin and its principle degradation product, anhydroeythromycin, to be determined during a period of sample storage at 4 degree C and minus 15 degree C. The method is sufficiently sensitive and precise and is thus highly suited for use in both pharmacokinetic and stability studies.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 36 , Fusigobius duospilusis described as a new species from several localities in the tropical Pacific and Indian oceans. This species differs from other species of Fusigobius in pectoral ray and gill-raker counts, coloration, reduced pelvic frenum, branching of the pelvic rays, presence of two large black spots on the first dorsal fin and shape of the first dorsal fin. The species is free living on sand. Males average a larger size than females. Sex ratios are uneven, with about twice as many females as males. Fusigobius longispinus Goren is recorded from several localities in the western Indian Ocean, where populations differ morphologically from Red Sea populations. Fusiogobius neophytus africanusls regarded as a synonym of F. neophytus.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 24 , Electrofishing surveys throughout Malawi have increased the number of mormyrid species known to occur in the country, expanded known ranges of the species and cast doubts on some earlier records. The distribution of each of the eight recorded species is given, and a key is provided for the identification of the species. The available evidence suggests that Gnathonemus nyasensis Worthington, 1933 is a junior synonym of Marcusenius livingstonii (Boulenger, 1898) a species described from the Ruvuma River of Tanzania. Geological evidence supports fish distribution evidence that indicates links between Lake Malawi and East Coast Rivers. Some affinities are also noted between Lake Malawi and Upper Zambezi/Zaire faunas.
