| dc.description.abstract | Research on the reproductive biology of squid (Uroteuthis sp.) caught in the
waters of the Malacca Strait, Belawan, North Sumatra, aims to determine the
growth and reproductive biology aspects of squid (Uroteuthis sp.) caught in the
waters of the Malacca Strait, Belawan, North Sumatra. This research was carried
out from January to March 2024. The number of squid (Uroteuthis chinensis)
samples was 148 with a total length of 210-950 mm and a total weight of 44-850
grams. Meanwhile, there are 132 squid (Uroteuthis duvaucelii) with a total length
of 144-640 mm and a total bbpt of 44-784 grams. The allometric growth pattern of
squid (Uroteuthis sp.) is negative with condition factor values classified as flat with
a range of 0.225-3.113 in squid (U. chinensis) and 0.418-5.044 in squid (U.
duvaucelii). Based on the growth of the von Bertalanffy equation, male squid (U.
chinensis) (L∞ and K) is 950 mm and 0.88 mm/year, while female squid (U.
chinensis) (L∞ and K) is 615 .6 mm and 0.87 mm/year. In squid (U. duvaucelii)
males (L∞ and K) are 397 mm and 0.69 mm/year, while squid (U. duvaucelii)
females (L∞ and K) are 629.5 mm and 1 .4 mm/year. For female squid (Uroteuthis
sp.), the value is Lc>Lm, while for males, the value is Lc<Lm, which indicates that
the female squid (Uroteuthis sp.) is still worth catching, while the male squid
(Uroteuthis sp.) is not worth catching. The reproduction of squid (Uroteuthis sp.)
shows that the sex ratio is unbalanced, namely 1:0.59 and 1:1.86, but the stock in
the waters is still considered ideal. The gonad maturity level of squid (Uroteuthis
sp.) is at TKG I-V stages, with the IKG value in line with the increase in TKG. Egg
fecundity ranges from 1,918−52,786 with a total spawner spawning pattern. | en_US |
