Biography:

Zaleha Kassim obtained her PhD. in Aquatic Biology in 2001 from Universiti Putra Malaysia. She did her Bachelor Degree in Biology in 1996 after working for 9 years as a trained high school teacher. She received her Diploma in Science and Education in 1983 from Universiti Pertanian Malaysia. She is one of the Malaysian member in Japanese Society for Promotion Science (JSPS), collaborating in zooplankton ecological research group with other members from Indonesia, Thailand, Vietnam and Japan. She is also a member of Malayan Nature Society, Asian Fisheries Society and Malaysian Society for Applied Biology. She frequently deliver advise and talk to Fisheries Department of Malaysia (DoF) and Farmer’s Organization Authority of Malaysia (LPP) on aquculture practises and impact on the environmental disturbances to natural habitat. She won the best inventor for copepod culture using organic waste in a competition organized by WiPo, Kippo and MyIPO in 2011. She also recieved award of recognition from Ministry of Education in 2012 for the commercialization effort of her research innovation, the copepod culture technique.

Title: Assemblage and Contribution of Copepods in Tropical Lagoon of Setiu, East Coast of Peninsular Malaysia

Abstract:

Planktonic organisms are the major contributor to the stability of an aquatic ecosystem. They include the small phyto-and zooplankton groups as well as the nekton groups. Five months samplings were carried out during the warm months between April to September 2015 in the coastal lagoon of Setiu, at the east coast of Peninsular Malaysia to understand the copepods assemblage and their contribution to the ecosystem. Three stations were selected, Station 1, fringing mangroves (05º41.618”N, 102º41.875”E - 05º41.646”N, 102º41.846”E), Station 2, open lagoon with seagrasses (05º41.158”N, 102º42.544”E - 05º41.203”N, 102º42.518”E) and Station 3, the river opening to the sea (05º40.482”N, 102º43.197”E - 05º40.520”N, 102º43.103”E). Zooplankton samples were collected using 60µ and 100µ plankton net. Small fishes were caught using seine nets (0.5cm2) in a 24hours sampling for gut content analysis. The lagoon water was generally in brackish water condition (16.28±7.46 - 27.05±2.10 ppt) with low pH (5.97±1.41 - 7.51±0.49). Copepods of at least 60µ size dominated all stations if compared to the size of 100µ and above. Copepod composition was dominated by Cyclopoida at Station 1 and Station 2, while Calanoida dominated Station 3. The difference in copepod dominancy among stations indicates the seawater influence which determines the copepod assemblages in the lagoon. Setiu lagoon could be an important nursery ground for many important marine species as indicated by the higher abundance of small-sized than the big-sized copepods. From the total of 34 small fishes caught in mangroves and seagrasses área, Harpacticoida dominated 14.3-92.5% of the food ítem while Calanoida contributed 30.0-75.0%. Further study on the prey-predator interaction would give a better picture of the complexity of copepods’ assemblages in the lagoon.
