CE14005 Blue Whiting Acoustic Survey

An acoustic survey targeting blue whiting (Micromesistius poutassou) spawning and post spawning aggregations in the north east Atlantic in 2014.    Spawning takes place from January through to April along the shelf edge from the southern Porcupine Bank area northwards to the Faroe/Shetland Ridge including offshore areas as the Rosemary, Hatton and Rockall Banks. Peak spawning occurs between mid-March and mid April and acoustic surveys are timed to occur during this phase. To facilitate a more coordinated spatio-temporal approach to the survey participating countries meet annually to discuss survey methods and define effort allocation at the ICES led Working Group International Pelagic Surveys (WGIPS).    The survey covered the core spawning area of blue whiting to the west of Scotland and the Western Isles. Coverage extended from the shelf slopes (250m) westward into the Rockall Trough. The survey was carried out in continuity from north to south and from south to north    The 2014 survey was part of an international collaborative survey using the vessels RV Celtic Explorer (Ireland), FV Fridtjof Nansen (Russia), RV Tridens (Netherlands) and the RV Magnus Heinason (Faroes).     Transect design and effort allocation was pre-agreed for each vessel. A parallel transect design was used to allow transect interlacing in co-surveyed target areas (east-west orientation). Acoustic data were collected using the Simrad ER60 scientific echosounder. Cruising speed was  maintained at a maximum of 10 Kts (knots) where possible.    Biological sampling was done using a single pelagic midwater trawl.All components of the catch from the trawl hauls were sorted and weighed; fish and other taxa were identified to species level. Age, length, weight, sex, stomach fullness and maturity data were recorded for individual blue whiting within a random 50 fish sample from each trawl haul with a further 100 random length and weight measurements were also taken. All blue whiting were aged onboard.     Visual observations for marine mammals were conducted during daylight hours. For each sighting, the species, group size, group composition and behavioural characteristics were recorded. Seabird surveys were also carried out.     Oceanographic data on temperature, depth and salinity (CTD) were collected at set stations. 1. Collect acoustic data on blue whiting spawning aggregations  2. Collect biological samples from directed trawling on fish echotraces to determine age structure and maturity state of survey stock   3. Collect CTD data  4. Conduct visual abundance surveys of marine mammals and seabirds

CE13015 Celtic Explorer Celtic Sea Herring Acoustic Survey 2013

This survey was conducted by the Marine Institute in Autumn 2013 as part of the annual Celtic Sea Herring Acoustic Survey. The aim of an acoustic survey is to determine the relative abundance of the target species. This information is then used to determine catch rates and management advice for the following year.    In the southwest of Ireland and the Celtic Sea herring are an important commercial species. Since 2004 the acoustic survey has been carried out in October on-board the RV Celtic Explorer. The geographical confines of the annual 21 day survey have been modified in recent years to include areas to the south of the main winter spawning grounds in an effort to identify the whereabouts of winter spawning fish before the annual inshore spawning migration.     The 2013 survey covered the area from Loop Head in ICES Division VIIb in Co. Clare, and extended south along the western seaboard covering the main bays and inlets in Divisions VIIj and VIIg, in the Celtic Sea.    For biological sampling, a single pelagic midwater trawl was used. 21 trawl hauls were carried out. All components of the catch from the trawl hauls were sorted and weighed; fish and other taxa were identified to species level. Length measurements of herring, sprat and pilchard were taken. Acoustic data were collected using the Simrad EK60 scientific echosounder. Visual marine mammal and seabird surveys were also conducted during daylight hours. Oceanographic data (conductivity, temperature and depth (CTD)) was collected at preset stations. The aim of the acoustic survey is to determine the relative abundance of the target species, herring. This information is then used to determine catch rates and management advice for the following year.    Other objectives include collecting physical oceanography (CTD) data and visual surveys for marine mammals and seabirds.

CE0814 Irish Groundfish Survey Legs 2/3

This survey was conducted on board the RV Celtic Explorer in 2008 by the Marine Institute (MI) as part of the annual groundfish survey to determine the distribution and abundance of commercial fish around Ireland.     The Irish Groundfish Survey (IGFS) forms part of the International Bottom Trawl Survey (IBTS) programme, an international survey effort coordinated by the International Council of the Exploration of the Sea (ICES). Each year the survey, taking place in Autumn/Winter, collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management. In particular the survey provides an index of the share of young fish in the stock, which in turn gives an indication of its spawning success. The IGFS contributes to Ireland’s international obligation to supply scientific data that support the implementation of the Common Fisheries Policy (CFP).     This survey is a series of demersal sampling trawls at pre-defineds stations. The 2008 survey took place over 2 legs. Leg 1, focused on the northerly ICES Area and took place in late September and early October, Leg 2, in the western and southern areas was carried out during November/December.    In order to make data as comparable as possible, each survey operates under a set of agreed standard protocols. Each tow is 30min long and takes place during daylight hours at 3.5-4 knots. Net geometry and ground contact is monitored and logged. All fish and commercial shellfish are sorted to species level prior to taking lengths and other biological measurements such as age, sex and maturity. The primary purpose of the Irish Groundfish Survey is to develop estimates of juvenile abundances for important commercial fish species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance. In addition, the Irish Groundfish Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations.

CE0811 Deepwater Fisheries Survey

The deepwater survey was conducted by Marine Institute (MI) and the National University of Ireland, Galway (NUIG) from 9th - 22nd September, 2008. This survey was the third in a series, carried out on the RV Celtic Explorer, to acquire fishery and hydrographic data on the continental slope to the north and west of Ireland, and on the Porcupine Bank. As in the previous two years the survey was again coordinated with the Scottish Fisheries Research Service.    This 2008 survey was carried out in the same three areas as 2006 and 2007. In each area trawl hauls were made at four depths, 500m, 1000m, 1500m and 1800 meters, along the slope. Conductivity, Temperature and Depth (CTD) transects were carried out as well as plankton sampling. At each station the entire catch was sorted to species level and weighed. Full biological sampling, length, weight, sex, maturity and age, was carried out on all commercial species. Additional biological sampling, without ageing, was carried out on all elasmobranchs and chimareids. All Invertebrates from each fishing tow were identified as far as possible and their catches weighed. A Marine Mammal Observer (MMO) was also present on board to conduct a visual survey for cetaceans. The main purpose of the survey was to collect biological data on the main deepwater fish species and  invertebrates. The fisheries data collected will provide information for assessment of deepwater  stock.    Other purposes for the survey were to collect CTD data at set stations, and to carry out visual observations for marine mammals and seabirds.

CE0809 North-west Herring Acoustic Survey

This survey was conducted by the Marine Institute on-board the RV Celtic Explorer in summer 2008 as part of the North West Herring Acoustic Survey.     The northwest and west coast (ICES Divisions VIaS and VIIb) herring acoustic survey programme was first established in 1994. This survey represents the first in the new time series. In 2004, a single spawing stock survey was carried out early in quarter 1 and continued until 2007. It was then decided that the survey should be incorporated into the larger coordinated Malin shelf survey. The survey was coordinated through the ICES Working Group of International Pelagic Surveys (WGIPS). Survey data on stock numbers at age are submitted to the ICES Herring Assessment Working Group (HAWG) and used in the annual stock assessment process.    The northwest and west coast (ICES Divisions VIaS and VIIb) herring stock is composed of two spawning components, autumn and winter spawners. Spawning covers a large geographical area and extends over a 4-month period from late September through to late March. Traditionally, fishing effort has been concentrated on spawning and pre-spawning aggregations. The autumn spawning component, which mostly occurs within VIIb and VIaS, feeds along the shelf break area to the west of the spawning grounds. The winter spawning component is found further north in VIaS. In VIaS, summer distribution extends from close inshore to the shelf break. Components of the winter spawning fish are known to undertake northward feeding migration into VIaN before returning in the winter to spawn along the Irish coast.    This survey, carried out between 18th June to 08th July, focused on the northwest and west coast of Ireland. To keep in line with existing survey methodology acoustic data collection was only undertaken during daylight hours (04:00 and 00:00). A systematic parallel transect design was adoptedwith a randomised start point. Transects were positioned running perpendicular to the lines of bathymetry where possible.    The acoustic data were collected using the Simrad ER60 scientific echosounder. For biological sampling, a single pelagic midwater trawl was used. 37 hauls were carried out. All components of the catch from the trawl hauls were sorted and weighed; fish and other taxa were identified to species level. Oceanographic stations were carried out during the survey at predetermined locations along the track. The aim of the acoustic survey is to determine the relative abundance of the target species, herring. This information is then used to determine catch rates and management advice for the following year.    Other objectives include collecting physical oceanography (CTD) data at predefined stations.

CE13001 Ocean Climate Sections and Geology Survey

This multidisciplinary survey took place over two legs in January 2013, led by the Marine Institute. The cruise incorporates physical, chemical and biological data gathering.     The first leg of the survey focused on the recovery of the PAP 1 weather buoy owned by UK Met Office and gliders from the Porcupine Abyssal Plain (PAP) site for the  National Oceanography Centre (NOC) and University of East Anglia (UEA). The second leg focused on oceanographic section and geological work for Geological Survey Ireland (GSI) and the servicing of the M6 weather buoy.    A total of 36 CTD sampling stations were occupied for a variety of parameters including nutrients, salinity and carbon measurements. Grab sampling and rock dredging was conducted at a number of additional stations. The main purpose of this annual cruise is to collect oceanographic data (such as CTD and nutrient sampling) which will contribute to establishing baseline oceanic weather and oceanic conditions from which future changes can be assessed.     In addition, the UK Met office weather buoy was recovered, and the M6 buoy serviced.
