“…The spawning season can last until June (Pina, 2000). Several studies have been undertaken on Alosa spp., mainly regarding age and growth (Walburg, 1960;Mennesson-Boisneau et al, 1986), migration patterns (Rameye et al, 1976;Loesch, 1987;Quinn And Adams, 1996), reproduction (Hoestlandt, 1958;Walburg, 1960;Nichols and Massmann, 1963;Loesch and Lund, 1977;Leggett and Carscadden, 1978;Loesch, 1987;Manyukas, 1989;Jessop, 1993;Ross et al, 1993;Mylonas et al, 1995;Pina, 2000, Olney et al, 2001, and recruitment (Johnson and Loesch, 1983;Esteves, 1999). However, published information on the reproductive biology of A. fallax is restricted to the accounts of Manyukas (1989), Quignard and Douchement (1991) and Pina (2000), which provide no detailed description of the histological development of the gonads.…”
