Abstract

Sygnathoides biaculeatus (Bloch, 1785 ) is one unique animal among other teleost fish. They have particulary unique mode of reproduction that involve the male carrying developing eggs in their brrood puch during the incubation. Aim of this study is to determine length-weight relationship and condition factors of Alligator pipefish Sygnathoides biaculeatus (Bloch, 1785) in Tanakeke Islands. Sampling was taken and observed from June to November 2018 at two sampling points, namely La’botallua and La’bokatoang. The length-weight relationship is analyzed based on the exponential equation formula W = aLb and the condition factor (K) is calculated based on the length and weight of the sample fish. At Labbotallua location, the regression equations obtained were male 0.2170L1.244 and female 0.5030L0.9400. At labbukatoang for the male is 0.8230L0.4604 and female 0.0430L1.7590. The results showed that the growth pattern of the male and female Sygnathoides biaculeatus (Bloch, 1785) in Labbotallua and Labbokatoang are negative or minor allometric, which means that they grow faster than body weight condition factors of male Sygnathoides biaculeatus (Bloch, 1785) is 1.3190 with a range of 0.6369-1.3190. At the Labbukatoang location, the male condition factor was with range 0.7689-1.8219. This value is indicating that the environment of alligator pipefish still in conditions that is suitable for the growth of alligator pipefish. © EM International.
