ABSTRACT

Length-weight relationship (LWR) and condition factor of seven fish species from the Temengor Reservoir, Peninsular Malaysia were analyzed. A total of 1155 individuals belonging to two families namely Nandidae and Cyprinidae were measured and weighed. The most highly represented family was Cyprinidae which comprised six species. Among these seven species, three species generally showed positive allometric growth, two species showed isometric growth and the other two species showed negative allometric growth. The exponent b value of LWR ranged between 2.601 (Oxygaster anomalura) and 3.157 (Cyclocheilichthys apogon) with a mean of 2.983. The lowest mean condition factor, K was recorded in O. anomalura (0.648 ± 0.131) while the highest value was observed in Pristolepis fasciata (2.194 ± 0.153). This study has contributed to the knowledge of fish populations in this economically important area that could assist fishery management scientists in carrying out future ecological studies in line with the strategies of conservation, restoration and management.

Keywords: Allometric growth; condition factor; fish populations; length-weight relationship; Temengor Reservoir

ABSTRAK

Hubungan panjang-berat (LWR) dan faktor keadaan bagi tujuh spesies ikan dari Empangan Temengor, Semenanjung Malaysia telah dianalisis. Sejumlah 1155 individu daripada dua famili iaitu Nandidae dan Cyprinidae telah diukur dan ditimbang. Famili yang diwakili paling tinggi ialah Cyprinidae yang terdiri daripada enam spesies. Antara tujuh spesies ini, tiga spesies menunjukkan pertumbuhan alometrik positif, dua spesies menunjukkan pertumbuhan isometrik dan dua spesies lagi menunjukkan pertumbuhan alometrik negatif. Nilai eksponen b daripada LWR berjulat antara 2.601 (Oxygaster anomalura) dan 3.157 (Cyclocheilichthys apogon) dengan purata 2.983. Purata faktor keadaan, K yang paling rendah direkodkan pada O. anomalura (0.648 ± 0.131) manakala nilai tertinggi direkodkan pada Pristolepis fasciata (2.194 ± 0.153). Kajian ini telah menyumbang kepada pengetahuan populasi ikan di kawasan yang penting daripada segi ekonomi yang dapat membantu saintis pengurusan perikanan dalam menjalankan kajian ekologi pada masa hadapan bersesuaian dengan strategi pemuliharaan, membaikpulih dan pengurusan.

Kata kunci: Empangan Temengor; faktor keadaan; hubungan panjang-berat; pertumbuhan alometrik; populasi ikan
