Climate Change Responsive Indigenous Knowledge Systems in Crop Farming in Albay Province, Philippines
Vol. 22, Issue 2, 2019Abstract:Identifying, documenting and analyzing indigenous knowledge systems (IKS) in crop farming can help develop sustainable technologies since those IKS have evolved through the test of time involving several generations of farmers that made the communities survive. This study was conceptualized and conducted under such context. This qualitative and descriptive study involved the most senior and longtime farmers in the study sites as sources of information. Focus group discussion (FGD) was the method...

Biofouling on nets and endobiosis leads to reduced shell growth in scallops (Pectinidae): A meta-analysis
Vol. 22, Issue 2, 2019Abstract:Biofouling has been generally viewed as a negative issue affecting the culture of bivalves around the world. One significant impact of biofouling is the reduction of growth of affected species. To quantify its effect on scallops, meta-analytic techniques were employed using secondary data from best available published studies. Using the random effects model, the study was able to determine a significant reduction in the growth of fouled scallop by about 24%. However, subgroup analysis revealed t...

Positive Effect of Suspended Culture to the Growth of Pectinids
Vol. 22, Issue 2, 2019Abstract:Scallop production from the wild is undeniably declining due to the natural and man-made perturbations. With this, aquaculture seems to be an essential way to restore and meet the economic demand in marine molluscs, which is one of the important sources of highly nutritious animal protein. Scallop culture falls into two categories: suspended and bottom culture. Though studies are available comparing the growth between these two different culture methods, information on the effect size as a quant...

Evaluation of Cytotoxicity and Genotoxicity of Canarium ovatum Engl. (Burseraceae) and Cocos nucifera L. (Arecaceae) Ethanolic Bark Extracts
Vol. 22, Issue 2, 2019Abstract:To further elucidate the potential of the pili and coconut barks in terms of their anticancer activity, their crude extracts were subjected to the sea urchin fertilization assay and Allium cepa test. These tests were conducted in order to determine the cytotoxicity and genotoxicity activities against the test subjects. The generated IC50 values are 0.54 mg/ml and 0.20 mg/ml for Canarium ovatum and Cocos nucifera, respectively. The sea urchin egg cells possess strong sensitivity against toxic age...
