“…However, the finding of the present study revealed that the growth pattern of the male and female fish was characterized by negative allometric (b values of 2.1602 and 2.2665), respectively. This was slightly different from the findings of previous observations of the species in Juata and Amal waters, which showed a b value of 2.59 and 3.00, respectively (Taqwa et al 2018). This implies that there is a possibility that individuals of the Bombay duck in Tarakan waters are getting smaller.…”

Abstract. Salim G, Handayani KR, Anggoro S, Indarjo A, Syakti AD, Ibrahim AJ, Ransangan J, Prakoso LY. 2020. Morphometric analysis of Harpodon nehereus, Harpiosquilla raphidea, and Scylla serrata in the coastal waters of Tarakan, North Kalimantan, Indonesia. Biodiversitas 21: 4829-4838. The Bombay duck (Harpodon nehereus), harpiosquillid mantis shrimp (Harpiosquilla raphidea), and giant mud crab (Scylla serrata) are among the commercially important fishery resources in Tarakan Island, North Kalimantan, Indonesia. This requires sustainable fisheries management to be in place since these resources have now become the main targets of fishing industry. However, sustainable fisheries management of these species is difficult because less is known about the species particularly its condition, fatness, and well-being. Hence, the current study was conducted to analyze the morphometric characteristics in order to deduce fishing pressure of the fish species in Tarakan waters. Data collection was achieved through field between September 2017 and April 2018. Morphometric characteristics (length, weight, width, and thickness) were collected throughout the sampling period. The length-weight relationship and condition factor were then estimated using the morphometric measurements. The data were then statistically analyzed either or combination of t-test, Chi-square, and the Mann-Whitney tests. The study revealed that all the three fish species (H. nehereus, Ha. raphidea, and S. serrata) populations in Tarakan waters were dominated by male individuals (M:F ratio; 1:0.81; 1:0.63; and 1:0.66, respectively). The length-weight analysis showed all fish were found to be smaller in size and exhibited negative allometric growth patterns. The analysis of condition factor also showed that the fish were dominated by flat and very flat body shapes. The current study suggests that the fish species may encounter some kinds of ecological disturbances that selectively removed female fish and larger individuals from the populations. However, more studies are needed to accurately identify those factors so that plans to effectively address the root cause could be incorporated in the sustainable fishery management tools of the fish resources.

“…This indicates that the growth pattern of male and female H. nehereus is allometric negative (b<3) which indicates that the gain of weight is slower than the gain of length. There is a slight difference from the findings of the preceding species observations in Juata and Amal waters which obtained b values of 2.59 and 3.00, respectively [4]. This means that there is a chance that individual Bombay ducks in Tarakan waters are getting smaller.…”

Nomei (Harpodon nehereus) is a which is found in the northern waters of Tarakan City which has a fairly high economic value. The purpose of the study to analyze the growth patterns and condition index of the fish in Tarakan waters. The research was conducted in two periods, namely the period January-February 2022 and June-July 2022. The research method used a quantitative descriptive method. Fish samples were collected from fisher and data observed were total length, total weight, and sex. In January, the sampled H. nehereus consisted of males (n = 69) and females (n = 231) with allometric negative growth and both fat (male = 50.7%) and thin (female = 48.1%) body type were found. In February 2022, the growth of males (n = 70) and females (n = 224) were positive allometric and both type of body shape were found, with sex ratio of male 48.6% and female 51.4%. In June 2022, the growth of males (n = 980) and females (n = 680) were negative allometric with body shape of both fat (male = 48.1%) and thin (female = 48.5%). In July 2022, the growth of male (n=1197) and female (n=822) were negative allometric with body shape fat (male=49.1%) and thin (female 47.8%). A better management of aquatic biological resources, especially the stock of nomei fish (H. nehereus), is crucial for a sustainable resource.
