The research was conducted in Percut Sei Tuan Aquatic with goblinfish (Neovespicula depressifrons) as the main object. Goblinfish caught at a brackish aquatic which is mangroves are grown. This study aimed to analyse relationship between weight-length, growth pattern, length-frequency distribution, and condition factors of goblin fish. Danish seines mesh size net 1 inch, ½ ¼ inch used for fishing. After fish caught, then measured total length weighed, measurements were laboratory. range 24-65 mm weight 0.2 - 3 g. resulting group consisted 7 groups class intervals 42-47 mode size. From analysis length-weight relationship, constant value b = 0.972 factor ranges from 0.90 1.37 an average CF > 1.
