© George Turner © George Species of the Day: Oreochromis karongae Oreochromis karongae is listed as ‘Endangered’ on the IUCN Red List of Threatened Species™. This fish is one of three ‘chambo’ species endemic to Lake Malawi, and can be seen in loose shoals in many areas of the lake. Like other Oreochromis they are maternal mouthbrooders, with the mother protecting the eggs in her mouth until they hatch, and often the juvenile fry continue to use her mouth for shelter when danger is present. Geographical range The chambo are the most valuable food fishes in Malawi, and are very important for local www.iucnredlist.org subsistence as well as commerce. Populations of this species, however, collapsed in the Help Save Species 1990s as a result of over-fishing, with as much as a 70% decline within 10 years. www.arkive.org This species is, however, very easy to maintain in captivity. Although formal management of fisheries in the lake has been in place since the 1930s, over-harvesting is still a problem. Greater enforcement of harvest levels is vital in order to minimize further losses of this species and other fishes in Lake Malawi. The latest IUCN Red List assessment, findings released today, shows that 21 per cent of freshwater species in continental Africa are threatened with extinction. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership: Species of the Day IUCN (including the Species Survival Commission), BirdLife is sponsored by International, Conservation International, NatureServe and Zoological Society of London..

Box 27, Monkey Bay, Malawi Corresponding author: [email protected] Abstract Size-at-50% maturity, age and growth, of Oreochromis (Nyasalapia) karongae (‘chambo’) in Lakes Malawi and Malombe were studied. Similar size-at-50% maturity and growth patterns were found for populations in Lake Malawi, but differences were observed for Lake Malombe populations, suggesting that current chambo fisheries management regulations, based on findings from the southern part of Lake Malawi, may be applicable to the central and southern parts of that lake, but not to Lake Malombe. Key words: Chambo, growth patterns, Malawi Résumé La maturité de la taille à 50%, l’âge et la croissance des Oreochromis (Nyasalapia) karongae (‘chambo’) dans les lacs Malawi et Malombe ont été étudiés. La maturité de taille à 50% et les modèles de croissance ont été trouvés semblables pour les populations du lac Malawi, mais des différences ont été observées pour des populations du lac Malombe, suggérant que les règlements courants de gestion des pêcheries de chambo, basés sur des résultats de la partie méridionale du lac Malawi, puissent être applicables aux parties centrales et méridionales de ce lac, mais pas au lac Malombe.

Tilapia Species and Geographical Distribution in Africa
Tilapia : Species and geographical distribution in Africa FAO/ASTF GCP/RAF/510/MUL: Enhancing capacity/risk reduction of emerging Tilapia Lake Virus (TiLV) to African tilapia aquaculture Blessing Mapfumo Fisheries & Aquaculture Advisor Secretariat: World Aquaculture Society African Chapter Zimbabwe [email protected] Facts and figures – Tilapia in Africa Tilapia - originated exclusively from Africa and Middle East Widely distributed all over Africa Several species have been introduced into many countries within Africa & worldwide for various objectives Almost all tilapia produced in Africa is locally consumed, with very limited exports (out of Africa) By far, Nile tilapia has become a major candidate for commercial aquaculture in Africa and worldwide Tilapia is a traditional and favourite dish in almost all countries of Africa Wild/Capture tilapia production in Africa (2017): >400,000 MT Tilapia aquaculture production in Africa (2017): 1.2 million MT Factors behind the wide distribution of tilapia • Habitat diversity is one of the major factors behind the wide distribution of tilapia. In Africa, for example, tilapia inhabit a wide range of ecologically and geographically different habitats eg rivers, lakes, swamps etc • Tilapia has thrived naturally in a wide range of environmental conditions, including desirable temperature, depths, oxygen, competition, food availability, productivity etc Tilapia Introductions Tilapias were introduced into many tropical, subtropical and temperate regions of the world during second half of the 20th century, mainly for the following reasons: i. For farming as food fish ii. Development of new fisheries (capture) iii. For recreational fishing iii For aquatic weed control iv For research purposes Aquaculture production of Tilapias Tilapia have become a favourable candidate species for Tilapia culture is now practised almost all aquaculture due to its: African countries.

O. Box 27; Monkey Bay, Malawi Abstract The study focusing on potential impact of climate change on Chambo (Oreochromis spp.) fishery was conducted in the west coast of Lake Malawi, Nkhotakota using 1991 to 2015 univariate time series data of Chambo catch (metric tons), atmospheric temperatures (°C) and annual precipitation (mm). The Chambo catch data were obtained from Monkey Bay Fisheries Research Station of the Malawi Fisheries Department and the data for temperature and annual precipitation was obtained from Meteorological Department. Using regression models, the study revealed a positive strong correlation between the annual precipitation and annual Chambo catch trend. The coefficient of polynomial regression model (R2) revealed that 74.89% of variation in Chambo annual catch trend was due to annual precipitation (mm). The t-value for temperatures (t=0.853) was not significant (P>0.05), while that of precipitation (t=6.418) was significant (P<0.05) suggesting that annual precipitation significantly influenced the annual Chambo catch trend. The study apparently showed that climate change significantly affects the total landed catch of Chambo in Lake Malawi.

Mitochondrial genomes of 26 cichlid species were amplified by long-range PCR followed by the 454 pyrosequencing on a GS Roche Junior platform. The primers for long-range PCR were designed specifically in the mitogenomic regions with low interspecific variability. The whole mitogenome of most species was amplified as three fragments using the following primer sets: for the region between position 2 500 bp and 7 300 bp (of mitogenome starting with tRNA-Phe), we used forward primers ZM2500F (5'-ACG ACC TCG ATG TTG GAT CAG GAC ATC C-3'), L2508KAW (Kawaguchi et al. 2001) or S-LA-16SF (Miya & Nishida 2000) and reverse primer ZM7350R (5'-TTA AGG CGT GGT CGT GGA AGT GAA GAA G-3'). The region between 7 300 bp and 12 300 bp was amplified using primers ZM7300F (5'-GCA CAT CCC TCC CAA CTA GGW TTT CAA GAT GC-3') and ZM12300R (5'-TTG CAC CAA GAG TTT TTG GTT CCT AAG ACC-3').
