Life-history reference points for management of an exploited tropical seahorse

Abstract: The present research provides the first demographic reference points for tropical seahorses, relevant to conservation of this largely tropical genus Hippocampus, which is listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II. Findings defined the life-history and in situ vital rates of the tiger tail seahorse, H. comes, expanding previous understanding of demographic diversity in reef fishes. We quantified growth, reproduction and survival rates, drawing on mark–recapture intervals from focal observations, underwater visual census and fisheries landings data. The smallest settled individual was 2.7 cm and first benthic cohorts measured 3.0–4.0 cm. Assuming individually variable growth, the mean parameters for the von Bertalanffy growth equation were Linf = 16.7 cm, K = 2.9 year–1 and t0 = 0.03. Physical maturity occurred at 9.3 cm, reproductive activity at 11.6 cm and annual recruitment during the dry, inter-monsoon window from February to May. Size-dependent survivorship ranged from 3.5% to 45.0% year–1 and longevity was ≥2.5 years. In H. comes, characteristics governing population turnover align with opportunistic strategists, whereas reproductive traits align more closely with equilibrium strategists. Non-extractive marine reserves are one management approach that could serve such intermediate strategists, providing refugia for colonisation, while protecting important large, fecund adults.

Spatial and temporal variation of abundance, biomass and diversity within marine reserves in the Philippines
Publication Type: Journal Article Year of Publication: 2010 Authors: Anticamara, JA, Zeller D, Vincent ACJ Journal: Diversity and Distributions Volume: 16 Issue: 4 Pagination: 529 - 536 Date Published: 07/2010 Keywords: Biodiversity, conservation, marine protected areas, no-take zones, overfishing, small-scale fisheries Abstract: Aim  The objective of this study was to investigate the influence of protection duration (years of fishing closure) and location (distance from shore) on reef fish diversity. Location  Danajon Double Barrier Reef, Bohol, Philippines. Methods  Reef fish abundance and size structure, by species, were obtained monthly using replicated underwater visual belt transects (n = 8; 70 × 5-m belt transects) over 3 years (2002–2005) at eight sites that included six marine reserves and two unprotected reef areas. We analysed species accumulation curves, diversity indices and abundance–biomass comparison (ABC) curves within and across the study sites to assess the influence of protection duration and location. Results  Analyses showed that longer protection duration impacted reef fish diversity at both inshore and offshore sites by shifting ABC curves from higher abundance than biomass curves at fished sites to higher biomass than abundance curves at most of the protected sites. Protection duration did not significantly influence either the rate of species accumulation within sites or the 12 diversity indices measured across the study sites. The offshore sites consistently showed higher rates of species accumulation and diversity indices values than inshore sites with similar protection duration. One protected offshore young marine reserve site that has been assessed as the least well-managed showed patterns more consistent with the fished sites. Main conclusions  Analyses showed that protection duration mainly impacted diversity by increasing the dominance of large-bodied species and enhancing total biomass.

Diversification and depletion in Vietnamese seahorse fisheries
Publication type: Thesis (Master of Science) Publisher: The University of British Columbia Date: 2016 Author: Allison Stocks Abstract The development of effective evidence-based management is limited by a lack of long-term records for many vulnerable marine species that are caught in small-scale fisheries. To address this data gap, I studied a small-scale fishery in southern Vietnam with a focus on seahorses (Hippocampus spp.), globally traded, cryptic fishes that are notably vulnerable to overexploitation. Using a combination of fisher interviews and catch landings surveys, I documented five fishing gears that regularly caught seahorses intentionally and/or incidentally: otter trawls, beam trawls, pair trawls, crab nets, and compressor diving. About 20% of fishers I studied specifically targeted seahorses and made the majority of their income from selling these fish; a novel finding. The seahorse catch consisted of three species – Hippocampus spinosissimus, H. kuda and H. trimaculatus – with catch composition varying by gear and fishing ground. Bottom trawl boats and compressor divers that targeted seahorses caught them at mean rates of 23 and 32 seahorses per day respectively, while those that caught seahorses incidentally caught 1 and 3 per day respectively. The total catch from the island from these two fishing methods was approximately 162,000–234,000 seahorses per year. This catch is up to four times higher than in other studied regions of Vietnam and throughout Southeast Asia. Fishers reported that seahorse catch rates had decreased by 86-95% from 2004 to 2014. Meanwhile, the landed value of seahorses had increased by 534
