Local responses to political policies and socio-economic change in the Keiskammahoek district, Ciskei: anthropological perspectives / Development Studies Working Paper, no. 55 / Development Studies Working Paper, no. 55De Wet, C J, Manona, C W, Palmer, Robin January 1992 (has links)
This report relates to research done in the Keiskammahoek district of the Ciskei (see Map No. l) during 1989 and early 1990, with the financial support of the Programme for Development Research (PRODDER) of the Human Sciences Research Council (HSRC) of South Africa. The project was designed and conducted against the background of previous research, and has served as a pilot project for a larger project, entitled "Socio- Economic Change and Development Planning in the Keiskammahoek District of the Ciskei". This larger project which is currently in progress, (and which has been funded by the Institute for Research Development of the HSRC, by the Chairman's Fund of Anglo-American and De Beers, and by Johannesburg Consolidated Investments Co Ltd), is intended to give rise to a process of consultation and planning, leading to various local-level development initiatives in the District. / Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

Previous issue date: 2015-08-26 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The spotted moray, Gymnothorax moringa, Muraenidae family, is an important species of marine fish, abundant in coral reefs, rocky bottoms and even in sandy areas covered with vegetation. It is very common in the Tropical Atlantic where it occurs along its western border, From North Carolina and Bermuda, to the southeast coats of Brazil. In the present work, the feeding habits of the species were studied, by means of its diet composition. With this objective, 403 stomachs were analyzed, of which only 126 (24.3%) had contents. Only seven food items were identified, all of them teleosts. The index of relative importance (IIR) was used to identify the order of importance of each item. The prey item with the highest IIR was the goatfish, Pseudopeneus maculatus, followed by other teleosts. The repletion index (empty ¼ filled ² / 4 filled and filled) was also determined, whereby 74.6% of the stomachs were empty, 8.5% ¼ filled, 3.1% ½ filled, and 12.7% were full. There was no stomach 3/4 filled. For the study of their reproductive biology, 416 specimens, caught from January 2013 to December 2014, were analyzed. It was possible to identify the sex of 370 individuals: 183 males, with a total length (CT) ranging from 47 cm to 109 cm (mean 73.8 cm) and 187 females, with CT between 47 cm and 97 cm (mean 70.0 cm). The average fertility was 30.332 oocytes. The monthly mean gonosomatic index (IGS) and the distribution of maturation stages suggest a higher reproductive activity for the species in Pernambuco coast, during summer months, between October and January. / A moréia-pintada, Gymnothorax moringa, pertencente à família Muraenidae, é uma importante espécie de peixe ósseo marinho, sendo abundante em fundos de coral, rochas e até mesmo em áreas arenosas com cobertura de vegetação. É muito comum no Atlântico Tropical onde ocorre, em sua margem ocidental, desde a Carolina do Norte e Bermudas, até o sudeste do Brasil. No presente trabalho, os aspectos alimentares da espécie foram estudados através da composição da sua dieta. Foram analisados 403 estômagos, dos quais apenas 126 (24,3%) apresentavam algum conteúdo. Foram identificados 7 itens alimentares, todos teleósteos, tendo sido utilizado o índice de importância relativa (IIR) para se estabelecer a ordem de importância de cada item. A presa com maior IIR foi o saramonete, Pseudopeneus maculatus, seguido de outos teleósteos. Também foi determinado o índice de repleção (vazio, ¼ preenchido, ½ preenchido, 3/4 preenchido e cheio), segundo o qual 74,6% dos estômagos encontravam-se vazios, 8,5% ¼ preenchidos, 3,1% ²/4 preenchidos e 12,7% encontravam-se cheios. Não houve estômagos com 3/4 preenchidos. Para o estudo de biologia reprodutiva, foram analisados 416 exemplares de moréia-pintada, capturados no período de janeiro de 2013 a dezembro de 2014, tendo sido possível a identificação do sexo de 370 indivíduos: 183 machos, com comprimento total (CT), variando entre 47 cm e 109 cm (média de 73,8 cm), e 187 fêmeas, com CT entre 47 cm e 97 cm, (média de 70,0 cm). A fecundidade media foi igual a 30.332 ovócitos. Os dados de variação mensal do IGS e dos estágios de maturação sugerem uma maior atividade reprodutiva para a espécie na costa pernambucana, nos meses de verão, entre outubro e janeiro.
