Heavy Metal Assessment in Water from Cockle Culture Areas, Kuala Selangor


January 2021 - The aim of the study is to assess the concerntration of selected heavy metals in waters
from cockle culture areas in Kuala Selangor, Malaysia. For this study eight(8) elements were selected"
due to their significant contribution to water pollution in Malaysia waters which are cadmium (Cd), 
chromium (Cr), copper (Cu), lead (Pb), mercury (Hg), total arsenic (As), selenium (Se) and zinc (Zn).

Seawater samples were collected from two main cockle culture areas in Selangor which are Kebun 
Kerang Kuala Selangor (KKKS), and Kebun Kerang Sabak Bernam (KKSB) from April to November 
2015.  In this study, Inductive Coupled Plasma Mass Spectrometer (ICP-MS) was used to measure 
the concerntration of Cd, Cr, Cu, Pb, Hg, As, Se and Zn respectively.

The results showed in general, selected heavy metals concerntration were lower than Interim Malaysia
Marine Water Quality Standards and Criteria (IMQWS) set by the Department of Environmental Malaysia.

Short Term Storage of Groupher's Sperm


January 2020 - Production of marine aquaculture has been increased year by year, but the problematic issue in broodstock quality (sperm, eggs, gamete) still remains.  In order to solve the problem, a sperm cryopreservation protocol was developed to supply sufficient gamete for the future. Sperm Cryopreservation and post thawing protocol are still in the improvision phase to reach sufficient grouper sperms stocks for short and long term preservation. The objective of this study is to find the best extender, storage method and dilution ratio for short storage sperm. An effective protocol was established by comparing the different solutions of the extender. The motility (MOT) between sperm diluted with extender and fresh sperm was compared and recorded daily.  The result indicated that the best dilution ratio sperm to the extender is 1:4. The motility of sperm in ASP lasts for 33 days for giant grouper (Epinephelus lanceolatus) and 23 days for tiger grouper (Epinephelus fuscoguttatus). As a conclusion, using ASP as an extender with a ratio of 1:4 is the best protocol for short term sperm storage.

Fish Virology at Fish Health Research Center (NaFish)


January 2019 - Research on fish and shrimp virology at  NaFish has been started since late 1990's under the aquaculture unit. The research was done in collaboration with JIRCAS on WSSV in shrimp, and at the same time fish tissue culture lab (NaFish) was establishe in the year  2002. Viral nervous necrosis (VNN) is a disease caused by betanodavirus and being reported in more than 50 fish species worldwide (tropical and cold water). Infected fish typically shows abnormal swimming behavior, skin darkening, anorexia, lethargy and swim bladder hyperinflation. Histologically, VNN cause vacuolation of the fish nervous system such as brain and eyes. In collaboration with Veterinary Research Institute (VRI),  the first local VNN strain from imported bawal emas (Trichinotus blochii)  has been successfully  isolated  in the year 2006. Currently, two CPEs (cytopathic effec) have been confirmed as VNN and many others isolates found in fish tissue culture are still under investigation. In Malaysia, VNN is endemic and can be easily isolated from the healthy looking fish. The endemic state of disease will limit the strategy of controlling and prevention. At hatchery level,regular monitoring VNN in broodstocks and fry stocks is important to ensure they are free from the virus which can cause great losses. With the success of VSS viral isolation and identification, NaFish has taken further steps  in the research.


Collaboration between FRI and CMDV: The Development of Red Tilapia Hybrid Growth Marker


05 December 2018 -  Red tilapia is the second largest fish produced after catfish in Malaysia. However, the production of tilapia has been found to decrease each year, from 51, 554 mt (2012) to 35, 996 mt (2016). The decrease in tilapia production has recalled actions to improve fish management strategies and tilapia culture practices. Among them, is to identify genes that facilitate the acceleration of growth which will help to shorten the culture period thus would increase the profitability to the farmers. The growth of fish is affected by the endogenous factor such as stock, strain, and species which directly involved with the genetic component of the fish. Traits associated with fast and efficient growth have a major influence on animal production. Traditional phenotype-based selection through natural selection and selective breeding is typically used to select growth traits, however, it requires several generations to optimize genetics improvement. In contrast, molecular genetics requires relatively less time to identify genes and trait linked markers for selection trait of interest.  Thus the objective of this study is to seek for the possibility of using molecular technique via molecular markers in the genetics enhancement program of red tilapia in the genetics enhancement program of red tilapia hybrid. This is a collaboration project between Fisheries Research Institute (FRI) and Centre for Marker Discovery and Validation (CMDV), MARDI.  The finding from this study will contribute to the understanding of the role of specific DNA sequence and could be used as a basis for the FRI on the selective breeding program of red tilapia hybrid.

As a result, 10 novel SNPs markers that associate to high growth performance traits of red Malaysian tilapia hybrid was successfully developed from this project. This finding will help to increase the effectiveness and accuracy in the broodstock selection in the genetics enhancements program. However, a proper SOP need to be developed along the usage of this markers as the environmental effect especially feed intake and water quality will also affect the performance of the fish.

Fisheries Mobile Information Package (FISHMiP)


February 2018 - Fisheries Reseach Institute Malaysia has been invented a device (FISHMiP) that can inform fisherman their fishing zone and bounderies between the states. ​This handheld  device FISHMiP is compatible with GARMIN GPS Map Series i.e., Garmin MONTANA 650, Garmin 64s, Garmin GPS Map 78s, Garmin DriveSmart 50LM ans etc. ​By using this device, the authorities can easily monitor fishing operation such as fishing at the gazetted areas, or accidentally entering neighbouring countries. We are seeking ​serious partners to invest in the project to commecialize the product. Please contact Mr. Hadzley for further information at 04-6263925/6.




Parasit Infection Caligus epidemicus Found in Marine Cultured Strain Red Tilapia (Oreochromis sp.) from Laguna Sri Tujuh, Kelantan, Malaysia


04 December 2017 - Red Tilapia is a common freswater species cultured by farmers in Malaysia. Lately, farmers are culturing red tilapia in marine environment as it fetches a better market price. Culturing of red tilapia in marine environment was reported in Perak (2012) and Kelantan (2014). A study was carried out on the presence of crustacean parasites in red tilapia cultured at marine environment in Laguna Sri Tujuh, Kelantan. Samples collected at the site indicare only Caligus sp. of crustacean ectoparasite was presence. The Caligus species was never reported in the freshwater cultured red tilapia in Malaysia. Parasitic infection in marine cultured were identified as Caligus epidemicus with prevalence of 100% and mean intensity of 19 parasites per fish. The examined red tilapia showed 60% had ulcer on the body. The finding highlights an urgent need to review the introduction of culturing strain red tilapia in marine environment. The current information can enhances our knowledge on ectoparasitic infestation scenario of red tilapia cultured in marine environment which can help to formulate a more structured control programme of parasite diseases. 


Survey on the Awareness, Acceptance and Preference of GIFT Tilapia in Malaysia


09 March 2017 -The aims of this survey are to evaluate the consumer awareness and acceptance towards GIFT tilapia in Malaysia and consumer preference of GIFT tilapia compared to red tilapia. The result of previous study on the acceptance of Gift tilapia among the Malaysian farmers indicated one of the main factor cause their interest not to culture GIFT tilapia is due to the unappealing physical appearance that make it less demand compared to red tilapia. This survey was conducted from 2-4 December 2016 during the “Malaysian Agriculture, Horticulture & Agro-tourism (MAHA) 2016” exhibition using a set of questionnaires and sensory evaluation test. The results showed that more than half of the respondent (62.5%) is not aware of the presence of GIFT tilapia. More than 80% of the consumer participated in the acceptance test like all of the GIFT attributes. There is a significant preference (P<0.05) among the consumers towards appearance, taste and texture of the red compared to GIFT tilapia. The promotion of GIFT Tilapia should be increased in order to accomplish the Department of Fisheries Malaysia (DOF) target to produce more GIFT tilapia.
