Resumen : EN Preliminary data of the length-weight relationship and reproduction of the bogueBoops boops off Gran Canaria (Canary Islands, Central-east Atlantic) areprovided. Two thousand and twenty-one individuals of bogue, ranging from 4 to 34cm TL, were obtained from purse seine commercial landing. Reproductionparameters as sex determination, duration of spawning season, size at firstmaturity and GSI variation along time were determinated based on macroscopicevaluation of gonads. The results obtained suggest that bogue is a total spawner,with a long spawning season extending from January to May. Size at first maturitywas 16.7 and 17.9 cm TL for males and females, respectively. The length-weightrelationship obtained showed a positive allometry in both sexesES Se presentan datos preliminares sobre la relación talla-peso y reproducción de laboga Boops boops en aguas de Gran Canaria (Islas Canarias, Atlántico Centro-Oriental). Los 2012 ejemplares examinados, obtenidos de capturas comercialescon cerco, presentaron tallas entre 4 y 34 cm TL. Se determinaron los parámetrosreproductivos, como la determinación del sexo, la duración del periodo de desove,talla de primera madurez y variaciones del GSI a lo largo del tiempo, a través delanálisis macroscópicamiente las gónadas. Los resultados sugieren que la boga esun desovador total con un largo periodo de puesta, que se extiende desde enero amayo, y cuya talla de primera madurez es 16.7 y 17.9 cm TL para machos yhembras, respectivamente.La relación talla-peso obtenida muestra una alometría positiva en ambos lossexos.
