Larval settlement behaviour of Coscinoderma sponges from the Torres Strait, Australia (MTSRF Project 1.3.2)

This experimental study of larval settlement behaviour of Coscinoderma mathewsi, undertaken in December 2009, explored some specific aspects of recruitment behaviour raised from the Torres Strait recuritment study.Research was conducted in tanks at Orpheus Island under controlled conditions to complement field recruitment studies in the Torres Strait (see separate metadata record). Coscinoderma larvae were obtained from Orpheus Island.This study determined specific pre-settlement larval behaviours including pre-competency periods and chemical and physical settlement cues.Synchronicity of spawning cycles between Orpheus and Torres Strait sponges were assessed. To explore specific aspects of recruitment behaviour Coscinoderma matthewsi. One component of a project in the Torres Straits focusing on sponges with potential for aquaculture. Other metadata are available for: 1) Abundance of Coscinoderma 2) Recruitment of Coscinoderma3) Spatial distribution of Dictyoceratid sponges across the central Torres Strait4) Effects of handling on sponge growth

本研究于2009年12月开展，旨在探索马修斯饰孔海绵（Coscinoderma mathewsi）的招募行为若干特定维度，同时拓展托雷斯海峡（Torres Strait）招募研究中的相关方向。实验于奥费斯岛（Orpheus Island）的受控环境水槽中开展，以辅助托雷斯海峡的野外招募研究（详见独立元数据记录）。研究所用的饰孔海绵（Coscinoderma）幼体均采集自奥费斯岛。本研究明确了若干附着前幼体行为特征，包括幼体预附着能力期（pre-competency periods）以及化学与物理附着诱导因子，并评估了奥费斯岛与托雷斯海峡海绵的产卵周期同步性。本研究为托雷斯海峡某项目的组成部分，该项目聚焦具备水产养殖潜力的海绵类群。其余相关元数据可覆盖以下主题：1）饰孔海绵属（Coscinoderma）种群丰度；2）饰孔海绵属幼体招募情况；3）托雷斯海峡中部网角海绵科（Dictyoceratid）海绵的空间分布特征；4）操作处理对海绵生长的影响。
