Cockles from Sungai Getting not safe for consuption

 
 
21 September 2015 - The public are advised not to consume cockles from Sungai Getting for fear that the shellfish may be contiminated by an algae phenomenon known as the 'red tide'. The sale of the cockles from this area also prohibited until the toxin level of the water has been assessed by the state Fisheries Department. The growth of red algae is a natural phenomenon and a large presence of such algae will cause the river water to appear red.
 
     
   
 


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.
