Abstract

Graphical Abstract Highlight Research A low sequence divergence of lemuru between Bali Strait and the northern latitude. S. lemuru migration route through ITF will maintain its nucleotide variation. The high haplotype diversity of lemuru is a testament to its adaptability. S. lemuru's high haplotype diversity supports their stock recovery in the Bali Strait. Two sardine species are morphologically and genetically highly distinct, even though they prefer overlapping water mass conditions from each other. Abstract Sardinella lemuru is known as the native pelagic fish of the Bali Strait. However, its presence has recently become challenging to find. This study aimed to validate S. lemuru using molecular taxonomy and link it to water circulations for sustainable management. It is the first study of relatively complete sequence data on S. lemuru in the Bali Strait. A total of 47 sequences were amplified using the control region gene of mitochondrial DNA. Other S. lemuru (n = 4) and Amblygaster sirm (n = 12) sequences were retrieved from GenBank. Low sequence divergence is observed in clade-1 of S. lemuru across the Bali Strait, Manado-Sulawesi, and Kudat-Malaysia. This is probably due to its migration using the main Indonesian ThroughFlow (ITF). There is an evolutionary divergence between two groups of S. lemurs, measuring 35.3%±4.1. The first signs of these cryptic groups were found at Canggu and Prigi, with 87 base-pair differences between the two groups. This study also presents strong evidence that A. sirm prefers overlapping water mass conditions with S. lemuru in the Bali Strait but is morphologically and genetically distinct. Notably, three samples of A. sirm in Kedonganan-Bali are clustered with other A. sirm locations passed by the primary and secondary South China Sea throughflow. The high genetic diversity of S. lemuru among Bali Strait sites demonstrates its adaptive ability, with scattered single-frequency haplotypes. The adaptive ability traits of S. lemuru support its stock recovery. The stock recovery recommendation is based on finding S. lemuru’s adaptive traits within their populations in suitable habitats and climatic conditions

Abstract

The objective of this study was to assess compliance to small-quantity lipid-based nutrient supplements (SQ-LNS) and associated factors. The community-based non randomized controlled intervention was conducted among 117 infants aged six months old in Bangkalan district and received a daily 20 g SQ-LNS (n=58) or three pieces biscuit (n=59) for six months. In SQ-LNS group, the compliance was 71.7%, 62.7%, 59.3% over one, three, and six-month intervention. The proportion of infant with compliance as recommended (7 sachets SQ-LNS per week) was 68.6%, 34.3%, 18.6%. In Biscuit group, the proportion was 96.6%, 92.8%, 91.1% and compliance as recommended (21 pieces per week) was 94.9%, 93.2%, 91.5%. Logistic regression analysis showed that low mother education (OR=3.67; 95%CI:1.14-11.74), food secure household (OR=3.87; 95%CI:1.26-11.88), high household dietary diversity (OR=3.78; 95%CI:1.20-11.89), and low social economy status (OR=3.81; 95%CI:1.16-12.56) were significantly associated with compliance of SQ-LNS as recommended. The mean of day and proportion of recommended daily serving consumed were 3.3 days and 98.8%, in SQ-LNS group; while in Biscuit group were 3.5 days and 87.2%. Mother reported that side effect of consuming SQ-LNS and biscuit were children felt bored (60.3%, 13.6%), vomiting (43.1%, 18.6%), suffering diarrhea (15.5%, 1.7%), respectively. The reason of irregular provision of SQ-LNS and biscuit were vomiting at the early consumption period response, boring, and did not like the smell/taste of SQ-LNS or biscuit. Mother perceived that the benefit of SQ-LNS and biscuit was increase body immunity, weight gain, appetite, and child become more active.
