Sobre la biología de la cinta (Cepola rubescens L.)

21 páginas, 12 figuras, 3 cuadros[EN] A study on the biology of Cepola rubescens, based chiefly on commercial catches along the Easthern mediterranean coast. Length averages 339 mm and weight 25 g in males and 35,7 g in females, relation between length and weight being almost linear. The commercial population is formed by individuals one (modal length 22-23 cm) and two (modal length 42-46 cm) years old. C. rubescens spawns between May and September. Females mature their gondas when one year old; males must wait until next year. Comparison of length distribution for two sexes, shows a marked dimorphism; the numerical proportion between individuals of different sex, and the minimum spawning lengths, suggest a possible proterogynic change of sex. Substantial evidence has benn offered by the observation of gonads with a maturing testicular portion and an atrophic ovarian one. Fat deposition shows maximum and minimum values related both to the reproductive cycle and to the quantitative variation of plankton. The examination of gastric contents evidences that Cepola derives its food mainly from plankton. The most characteristic copepoda of our waters have been recorded as food items, along with some species not recorded previously (Diaixis hibernica and Scottocalanus persecans) in our coasts[ES] Esta especie recibe en España muy diversos nombres, tales como cinta, látigo, beta, etc., que en su mayoría hacen referencia a su forma extraordinariamente alargada en relación con la altura de su cuerpo. En las costas mediterráneas se presenta con mucha frecuencia y, en numerosas ocasiones, destaca por su cantidad dentro de las capturas totales realizadas por los pesqueros; puede decirse, por tanto, que, si bien por su calidad no tiene gran interés comercial, presenta bastante importancia en lo que a la cantidad se refiere.
