Global extinction risk for seahorses, pipefishes and their near relatives (Syngnathiformes)

Few marine taxa have been comprehensively assessed for their conservation status, despite heavy pressures from fishing, habitat degradation and climate change. Here we report on the first global assessment of extinction risk for 300 species of syngnathiform fishes known as of 2017, using the IUCN Red List criteria. This order of bony teleosts is dominated … Read more Global extinction risk for seahorses, pipefishes and their near relatives (Syngnathiformes)

State of seahorse fisheries in India, nearly two decades after they were banned

Implementing a ban on fishing specific taxa is difficult enough without the added complexity of the taxa being primarily obtained as incidental catch. Most measures for restricting capture and trade to sustainable levels are directed towards targeted species, while overlooking the needs of incidentally caught species. Our study investigates the exploitation and conservation of seahorses … Read more State of seahorse fisheries in India, nearly two decades after they were banned

Holding governments accountable for their commitments: CITES Review of Significant Trade for a very high-volume taxon

Highlights CITES Review of Significant Trade (RST) is not improving implementation as intended. Our seahorse work shows that CITES needs to make five improvements to RST: Move beyond requesting outputs (e.g. reports) to recommend meaningful action. Scrutinize and track export suspensions declared during the process. Formally involve species experts, and fund such experts. Abstract Actions … Read more Holding governments accountable for their commitments: CITES Review of Significant Trade for a very high-volume taxon

Measuring the long-term success of small-scale marine protected areas in a Philippine reef fishery

Tropical coral reefs are subject to multiple pressures from both natural and anthropogenic sources. These pressures have caused widespread declines in reef health, resulting in the increased use of spatial management tools such as marine protected areas (MPAs). MPAs have proven generally effective if well designed and enforced, but there are limited long-term studies investigating … Read more Measuring the long-term success of small-scale marine protected areas in a Philippine reef fishery

China’s policies on bottom trawl fisheries over seven decades (1949–2018)

To pursue sustainable fisheries, the world needs to constrain bottom trawling (BT) through effective management. Such change is particularly urgent for China, which operates one of the largest bottom-trawl fisheries (BTF) both in and beyond its waters. We provide the first comprehensive review of China’s approach to BTF over seven decades (1949–2018) based on bibliometric … Read more China’s policies on bottom trawl fisheries over seven decades (1949–2018)

Catch and trade bans for seahorses can be negated by non‐selective fisheries

All seahorse species (genus Hippocampus) are listed under Schedule I of India’s Wild Life Protection Act, making all capture and trade of seahorses illegal. In the more than 15 years since the ban, little work has been done to assess its effects on seahorse conservation. Between 2015 and 2017, fisheries and trade surveys were conducted … Read more Catch and trade bans for seahorses can be negated by non‐selective fisheries

Realities of offering advice to governments on CITES

Article impact statement: Only when conservationists consider the perspective of government can they realize implementing their own advice is not as easy as it sounds. Abstract: What happens when those who provide conservation advice are required to take policy and management action based on that advice? Conservation advocates and scientists often try to prompt regulatory … Read more Realities of offering advice to governments on CITES

How much is enough? Improving participatory mapping using area rarefaction curves

Abstract Participatory mapping is a valuable approach for documenting the influence of human activities on species, ecosystems, and ecosystem services, as well as the variability of human activities over space and time. This method is particularly valuable in data-poor systems; however, there has never been a systematic approach for identifying the total number of respondents … Read more How much is enough?

A holistic investigation of the ecological correlates of abundance and body size for the endangered White’s seahorse Hippocampus whitei

Analysing the associations between the endangered White’s seahorse Hippocampus whitei and characteristics of its environment (including habitat, prey and predator variables) in an estuary in New South Wales, Australia, revealed that seahorses had a greater number of significant associations with environmental correlates within a single seagrass bed than among seagrass beds. Predator abundance was negatively correlated … Read more A holistic investigation of the ecological correlates of abundance and body size for the endangered White’s seahorse Hippocampus whitei

Using cumulative-human-impact models to reveal global threat patterns for seahorses

Article impact statement: : Modeling and mapping human impacts can reveal conservation status and threat patterns for data‐poor marine species. Abstract Understanding the threats acting upon marine organisms and their conservation status is vital but challenging given a paucity of data. Here we provide a global‐scale study of cumulative human impact (CHI) and conservation status of … Read more Using cumulative-human-impact models to reveal global threat patterns for seahorses
