The Integrated Kaipara Harbour Management Group (IKHMG) promotes the integrated management, inter‐agency coordination and kaitiakitanga of the Kaipara Harbour and its catchment. Led by the hapū (subtribe) Te Uri o Hau, the group is a collective of stakeholders and community. In 2013, the Institute of Environmental Science and Research (ESR) and Te Uri o Hau examined the IKHMG to understand what enables and hinders mātauranga‐i...

Whakataukī are part of a strongly developed Māori oral tradition that conveys critical information about aspects of life, society and tribal memory, including ecological knowledge. Such codified knowledge depends on language use and structure as a key mechanism for cultural transmission. Additionally, many meanings may not be apparent without knowing the historical, cultural and linguistic context from which the whakataukī ori...

Fisheries management has an important role in sustaining fisheries‐dependent cultures. We describe the cultural values of the Mōtū kahawai ( Arripis trutta ) fishery for Te Whānau‐a‐Hikarukutai/Ngāti Horomoana (TWAH/NH). Using a kaupapa‐Māori approach and culturally appropriate social science methods, cultural values of the Mōtū kahawai fishery were shared. The Identified Cultural Influence (ICI) index determined if kahawai is...

Motivation to improve commercial fishing technology is changing from ‘how can we catch more fish’ to ‘how can we reduce the impact of fishing on the environment’. To implement new fisheries technologies and innovations, it is important to have sources of innovative ideas for improvement, and processes to allow the uptake and transition from old to new technologies. One fishery that is undergoing a technology transition is the...

This article discusses a marine research project which prioritised mātauranga Māori (Māori knowledge systems) to generate common management approaches and responses for the taonga (culturally important) species; Kūtai, Perna canaliculus , Green Lipped Mussel populations in Ōhiwa harbour, Aotearoa New Zealand. Findings from the trans‐disciplinary marine research project were used to develop a mussel management action plan (MMAP...

Representative sampling of crayfish in streams is often impractical, especially in non‐wadable habitats, or in areas with soft substrates. Whakaweku are artificial habitats made from bracken fern ( Pteridium esculentum ) that can be used successfully in a range of habitats. We compared whakaweku, minnow traps, fyke nets and electrofishing for sampling freshwater crayfish (kōura; Paranephrops planifrons ) and bullies (toi toi;...

Our waterways, particularly in urban environments, are subject to increasing pressures from human activity. Similarly, urbanisation has irreversibly changed the Māori cultural experience of their natural world including freshwater ecosystems. The Water Warriors is a collaborative project between Te Pā o Rākaihautū and Hagley Community College that was established to look after the waterways and re‐connect rangatahi (youth) wit...

As Aotearoa New Zealand grapples with developing solutions to complex issues surrounding its unique freshwater and marine biological heritage, there is a growing recognition that mātauranga Māori can be ‘unlocked’ and used with great effect alongside western science. Examples where appropriate consideration and development of robust methodologies for the application of mātauranga Māori coexisting alongside western science are...

Taiāpure (local fishery) are Customary fisheries Protection Areas (CPAs) designed to make better provision for rangatiratanga (Māori chieftainship) under Article II of te Tiriti o Waitangi. The East Otago Taiāpure was applied for in 1992 and finally gazetted in 1999. It has been twenty‐six years since the East Otago Taiāpure was applied for and the East Otago Taiāpure Management Committee has incorporated mātauranga‐ā‐hapū (su...

This study aimed to develop quantitative relationships for Maori cultural values supported by streamflow. We examined the results of a Cultural Flow Preference Study (CFPS) for five streams in Canterbury, New Zealand, and used mixed effects models to quantify how observed streamflow supported scores for Overall Health (OH). Relationships between streamflow and OH differed between sites and assessors within each site. Ignoring...

Estuaries support a wide range of human activities and values, but are one of the most anthropogenically impacted ecosystems in the world. Ki uta ki tai is a holistic view of waterways that is embodied within Ngāi Tahu environmental management, which acknowledges the connectivity between environmental systems and people with the environment. While this philosophy is referred to within current policies, management does not effe...

Moohiotanga Tuku Iho, contemporary maatauranga and western science were used to classify the mauri (life force) of wai (water) in Matahuru Awa (river) in North Waikato. Moohiotanga Tuku Iho is tuupuna (ancestral) knowledge passed down through generations and together with local classifications were the guiding principles for using attributes of Taaonga Tuku Iho (treasures inherited) as parameters to classify the mauri of wai....

The Murihiku Cultural Water Classification System is founded on partnerships between people, disciplines and knowledge systems. This freshwater management framework is being developed at the scale of the Te Ara Koroka Pounamu Trail. Numerous barriers prevented Ngāi Tahu ki Murihiku use of the trail from around the 1880s; however, this cultural landscape and the values, beliefs and practices it supports (past, present and futur...

Te Awa o te Atua, known today as the Tarawera River, lies in the Bay of Plenty, North Island, New Zealand. Despite its immense importance to iwi, it has been subject to intense anthropogenic pressures and modification over the past century. Ngāti Rangitihi, one iwi kaitiaki of the river, wanted to understand how the mauri of Te Awa o te Atua has been impacted, with the ultimate aim of revitalising the mauri. Drawing from mātau...

The global production and yield of shrimp ponds depend on multiple factors, and an unexpected variation in production parameters could be an indicator of pathological events such as white spot disease (WSD) outbreaks in a syndromic surveillance system. Using the production data from 7139 production cycles at farm level collected at two Mexican states (Sonora and Sinaloa) from 2004 to 2011, an ecological survey (also called cor...

In aquaculture, feeding is the primary factor determining efficiency and cost, so it is important to know when to stop feeding to maximize efficiency. Until now, fish feeding has been mostly based on artificial discrimination, which is usually time‐consuming and laborious. In recent years, intelligent feeding control according to changes in behaviour and growth status has gained increasing attention. This approach involves man...

The use of antibiotics in the aquafeeds to mitigate infectious diseases or to boost growth performance is commonly practiced. Recently, the prophylactic use of antibiotics and chemotherapies have been criticized which eventually led to their ban in aquaculture by law on many countries. In view of the current restrictions on antibiotic use, there is a critical need to evaluate other possible alternatives. One potential substitu...

Ornamental aquaculture nutrition is profoundly different from conventional aquaculture nutrition from several points of views as the prices, finality and diversity. This paper tries to answer to some simple questions: do modern ornamental fish feeds reflect more physiological fish needs or aquarist expectations? What are the driving forces behind the modern aquarium nutrition? On the light of the considerations made in this pa...

Improving feed efficiency ( FE ) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30–70% of total production costs in aquaculture; much work has been done on nutritional and husbandry approaches to improve FE but only a limited amount of research has been devoted to using genetics, despite its potential. This paper reviews past work to impro...

This study presents a review of the microbiological standards and associated monitoring practices for classification of commercial shellfish production areas in force in Brazil, European Union and United States of America. The classification systems are not immediately comparable principally because some regulations are based on the monitoring of water and others of shellfish flesh. To create a common baseline to compare these...

The increased demand for food fish, together with the banning of antibiotics for fish growth promotion and the greater public awareness for healthy fish production, led to an increased interest in the potential of functional feeds as health promoters. Prebiotics are functional ingredients that are used in fish, being reported to be associated with improvements in growth, feed efficiency, gut microbiota, digestive enzyme activi...

The academic interest in the production of soft‐shell swimming crabs has increased in direct proportion to the increasing demand worldwide for this gastronomic delicacy. The techniques of obtaining this product are essentially based on the maintenance of swimming crabs at premoult stage in open, semi‐closed or closed farming systems, until the moment of moulting. These different types of systems reflect the biological e enviro...
