Reported densities for seahorses we

Reported densities for seahorses were comparable with those found for
temperate pipefish and seadragon species (all syngnathids): five pipefish species
in a Swedish seagrass bed had a total density of 0
04m2 (grid survey, Vincent
et al., 1995); Syngnathus leptorhynchus Girard occurred at densities ranging
from 0
02 to 0
1m2 in an Oregon seagrass bed (transect survey, Bayer,
1980); densities of Stigmatopora argus Richardson were 0
036–0
107m2 in
Southeastern Tasmania (transect survey, Jordan et al., 1998); and Phycodurus
eques Gu¨ nther, the leafy seadragon, was calculated to occur at a density of
0
006m2 in South Australia (Connolly et al., 2002). Reported seahorse densities
could be similar in fished and unfished populations, but the low densities in
at least some populations probably derived from overexploitation. For example,
Filipino fishers reported patchy H. comes densities as high as 20m2 on coral,
or 10m2 in seagrass in the 1960s (A. Vincent & M. Pajaro, unpubl. data),
while they were found at only 0
02m2 in the late 1990s (Perante et al., 2002).

Melaporkan kepadatan untuk kuda laut yang sebanding dengan yang ditemukan untukiklim pipefish dan seadragon spesies (semua syngnathids): lima spesies pipefishdi Swedia lamun tidur memiliki total kepadatan 0 04m 2 (survei grid, Vincentet al., 1995); Syngnathus leptorhynchus Girard terjadi pada kepadatan mulaidari 0 1 02-0 m 2 di Oregon lamun (transect survei, Bayer,1980); kepadatan Stigmatopora argus Richardson adalah 0 036-0 107m 2 diTenggara Tasmania (transect survei, Jordan et al., 1998); dan Phycoduruseques Gu¨ nther, seadragon berdaun, dihitung terjadi pada kepadatan0 006m 2 di Australia Selatan (Connolly et al., 2002). Melaporkan seahorse kepadatanbisa mirip dalam populasi penuhi dan unfished, tetapi kepadatan rendah dipopulasi setidaknya beberapa mungkin berasal dari pemanfaatan berlebihan. Misalnya,Nelayan Filipina dilaporkan tambal sulam H. datang kepadatan setinggi 20m 2 pada karang,atau 10m 2 di lamun di tahun 1960-an (A. Vincent & M. Pajaro, unpubl data),sementara mereka ditemukan di hanya 0 02m 2 di akhir 1990-an (Perante et al., 2002).
