Length-weight relationships and condition index of Pokea clams (Batissa violacea var. celebensis, von Martens 1897) in the Laeya River, Southeast Sulawesi, Indonesia

The length-weight relationship and condition index of pokea clams in the Laeya River are not fully known. This study was aimed to determine the length-weight relationship and condition index of pokea clams in the Laeya River, Southeast Sulawesi. This research was conducted 10 months from May 2016 to February 2017 in the Laeya River, Southeast Sulawesi. Pokea clams are collected using a shovel. The length and weight of each clam was using calipers and analytical scales with accuracy of 0.05 mm and 0.01 g, respectively. The weight of the shell and dried meat was obtained by drying the shells first using an oven and weighing using an analytical balance with an accuracy of 0.01 g and 0.0001 g, respectively. The results showed that the relationship between length and weight of pokea clams in males and females were 2.61 and 2.78, respectively; with R2 values of 0.89 and 0.93, respectively. The highest b values for males and females were found in July with values of 3.03 and 2.94, respectively. The lowest b value was found in November with values of 2.45 and 2.46, respectively. The condition index values for males and females were 4.7 ± 2.2 and 5.17 ± 2.32, respectively. The highest condition index was found in May with values of 6.00 ± 3.07 and 7.83 ± 2.55, respectively. The condition index values for males and females increased with increasing shell size. Male and female at the largest size (6.01-6.05 cm) had the highest index with values of 8.05 ± 6.41 and 9.12 ± 3.38, respectively. In conclusions, the growth was negative allometric pattern, condition index was in fat category, and had peak spawning in July and experienced partial spawning in September-February

Growth and condition index of

The somatic growth and condition index (CI) of pokea population aren’t yet fully known in the Lasolo river. This research aims to decide the somatic growth relationship between length and weight as well as the condition factor of pokea population. This research was carried out in the Lasolo river from January-December 2014. Pokea clams were taken from the river bed with traditional tool (tangge). The length and total weight of the clams were determined by employing a caliper with a precision of 0.5 cm and a digital scale with an accuracy of 0.01g. Meat and shells were then dried in an oven at 70°C about 48 hours. The dry weight of the meat and the shells of the pokea clams were weighed using a digital scale with an accuracy of 0.0001 g. Calculations obtained average b parameter values of the males and females about 2.52 and 2.70, respectively. The b values for both sex of clams were 2.37-3.05 and 2.24-3.15, respectively, which were within the negative allometric category. The CI values of the male (3.98±1.44) and female (4.27±1.52) putting them in the fat category. The condition index experienced three local peak periods in February-March, June, and November-December
