2 1 Introduction Given the importance of Merluccius paradoxus for the South-African and Namibian fisheries surprisingly little is known about the early life stages of the species. There are anecdotal information on spawning grounds (Crawford et al., 1987; Hutchings et al., 2002) and some information on peak spawning periods is also gathered from the fisheries (B. Rose, Irvin and Johnson, Cape Town, unpublished data and pers. comm.). Drifts route of eggs and larvae was studied by Stenevik et al. (2008) and it is well established through surveys that the area between Hondeklip Bay and Orange River holds large amount of juvenile fish and this is also the only area where small M. paradoxus less than 5 cm is encountered in the bottom trawl (Strømme et al., 2005). The survey carried out in February-March 2005 confirmed that the area north of Hondeklip Bay held the smallest fish, and as it grew bigger it migrated omnidirectional from this site. That the area between Hondeklip Bay and Orange River forms the main nursery area for the M. paradoxus seems quite evident. However, the pelagic stage from early larvae until they show up in the bottom trawl is poorly studied and the objective if the survey was to put more light on this phase of the life cycle. 2 Material and Methods 2.1 Registration of weather conditions The underway weather data aboard Dr. Fridtjof Nansen are logged with the Aanderaa Weather Station unit fitted with the following sensors: Sensor type Measurement units Air temperature Degrees C Wind speed M/s Solar radiation W/m 2 Wind direction Degrees re. the magnetic N. Pole Sea surface temperature Degrees C All sensors but Sea surface temperature (SST) are mounted on a mast positioned midships, at about 20 meters above the sea level. The SST sensor is located at the intake of the water 2

3 for cooling the engine and it readings are representative to a water layer at about 5 meters below the sea level. The weather station data were logged continuously throughout the survey. The results presented in this report are based on a standard output from the logging system comprising one nautical mile averages along the ship s track. 2.2 Hydrography The data on temperature salinity and oxygen were collected with a CTD Seabird 9 plus probe between the surface and 10 meters off the bottom. CTDs were made at each station. In addition, water bottle samples for oxygen and salinity calibrations were taken at most CTD stations. The salinity samples were analysed with the Guildline Portasal salinometer unit. The laboratory conditions onboard are suitable to detect deviations between the CTD and in situ samples at a level of of salinity units. Since no deviations reaching or exceeding this range were detected, the salinity values based on the factory calibration of the conductivity sensor are used throughout this report. The samples for dissolved oxygen were titrated within 12 hours of sample collection, using the standard Winkler method. 2.3 Trawl sampling The small 'Åkrahamn' pelagic trawl which has m vertical opening under normal operation was used during the survey and was connected with the Multisampler. The multisampler is advantageous because it has three cod-ends that can be opened and closed at any depth. It can therefore take three separate discrete samples in each hauls. Each net was typically open for 10 min during trawling. The mesh size in the cod-ends was 12 mm. The bottom trawl has a 31 m headline and a 47 m footrope fitted with a 12" rubber bobbins gear. The codend has 20 mm meshes, and has an inner net with 10 mm mesh size. The vertical opening is about 5.5 m. The distance between the wing tips is about 18 m during towing. The sweeps are 40 m long. The trawl doors are 'Thyborøen' combi, 8 m 2 and weigh 2000 kg. The door spreading is about 45 m when using restraining rope. Trawling was 3

4 conducted for species identification only and no restraining rope was therefore used during the survey. Typical trawl time was min. The SCANMAR system was used during all trawl hauls. This equipment consists of sensors, a hydrophone, a receiver, a display unit and a battery charger. Communication between sensors and ship is based on acoustic transmission. The doors are fitted with sensors to provide information on their distance and a height sensor is fitted on the bottom trawl to measure the trawl opening and provide information on clearance and bottom contact. The pelagic trawls are equipped with a trawl eye that provides information about the trawl opening and the distance of the footrope to the bottom. A pressure sensor is used to show the depth on the headline. 2.4 Juvenile sampling with Methot The Methot frame trawl has a mesh size of the inner nets is 7 mm with a cod-end of 1mm mesh size. The Methot sampler was deployed from the stern gate using a 12 mm cable on one of the trawl net winches. The Methot sampler was only used during night time due to well known problems with avoidance when using the sampler during daytime. A Scanmar depth sensor was mounted on top of the frame, and depth was monitored on the bridge during tows. The sampler was towed in a double oblique haul from the surface to 10m above bottom. 2.5 Repeat station After searching for a while, relatively high numbers of juveniles were found close to the 200 m isobaths at 30 o 06.9S, 16 o 001.0E and the first Multisampler haul was conducted on 1 st March 23:00 local time. Relatively high numbers of M. paradoxus were caught in the first pelagic trawl and the vessel stayed in the area with the following sampling plan: Station at the same position every 3 hour CTD on every station Multisampler on every station Bottom trawl Once during nighttime (02:00-04:00) Twice during daytime (08:00-12:00 and 15:00-18:00) Methot once during night (21:00-03:00) 4

5 Due to the problems experienced with the trawl door winch some of the hauls had to be cancelled and during the repeat station, 7 pelagic hauls with Multisampler, two Methot hauls and one bottom trawl were conducted. 3 Narrative The scientific staff consisted of: From MCM, South Africa: Marek Lipinski (teamleader), Sobahle Somhlaba Interns, South Africa: Garth Walters, Jessica Escobar, Brendon Lee, Laurel Abels, Margit Wilhelm, Josafat K. Hiwana From NatMIRC, Namibia Kondja Amutenya, Matthew Hangome From IMR, Norway: Erling Kåre Stenevik (cruise leader), Diana Zaera, Jan Frode Wilhelmsen, Terje Hovland The vessel departed Walvis Bay 21 February at 12:00 and started steaming southward towards the Orange Bank. Due to strong southerly winds (strong gale in periods) the steaming speed was reduced. Arrived at the first station off Panter Head (27 o 56 S) on 22 February at 11:00 and started station work with CTD and pelagic trawl with Multisampler mounted in order to get three depth discrete samples from each station. Pelagic trawls were conducted on-station during daytime and the sampling depths of the three nets were selected in accordance with hydroacoustic registrations. When there were no significant hydroacoustic recordings, the first net was towed close to the bottom, the second net in an oblique haul towards ca 25m depth and the upper net at about 25 m depth. During nighttime, Methot net was used on-station in a double oblique haul between the surface and ca 10 m above the bottom. Stations were positioned every 15 nm on transects perpendicular to the coast with 15 nm between transects. The survey covered the shelf and upper slope between 100m and 300m bottom depth (figure 1). It was decided to spend some time on investigating the diel vertical migration pattern of juvenile M. paradoxus in an area where sufficient concentrations of the juveniles were found. After searching for a while, relatively high numbers of juveniles were found close to the 200m isobaths at 30 o 06.9S, 16 o 001E and it was decided to do a repeat station there. The 5

6 first Multisampler haul was conducted on 1 st March at 23:00 local time (St 80). Experienced some problems with the counter sensor on the port trawl door winch and some of the hauls on the repeat station had to be cancelled. On 3 rd March at 08:30 station work on transects was resumed. The station work was terminated on 4 th March at 07:00 and the vessel started steaming towards Cape Town where it docked on 5 th March at 11:00. 6

Only very few juveniles were found 11

12 pelagically except for at the repeat station, and they were all found between Orange River and Hondeklip Bay (figure 15). No juveniles smaller than 5 cm was found during the survey. In the area where the repeat station was conducted, relatively high concentrations of 6-20 cm juveniles were found. The results from the repeat station (figure 16) showed that these juveniles performed vertical migration by being close to bottom during daytime and lifting up from the bottom during night time. There were differences in migration between size classes. Overall, the smaller juveniles (7-13 cm) moved close to the surface during night time while the larger juveniles stayed in the deeper layers (figure 17). Average size of juveniles ranged from 12.9 cm to 16.0 cm, from 8.8 mm to 12.3 cm and from 8.5 cm to 9.7 cm in the nearbottom, mid-water and near-surface hauls, respectively. No juveniles were caught in the pelagic trawl during daytime indicating that even the small juveniles were settled to the bottom during daylight hours. 4.4 Feeding In order to analyse feeding activity, 24 juvenile M paradoxus from the first pelagic trawl on the repeat station were analysed for stomach content (table 1). The juveniles were all sampled at night time in the near-surface layer (30-40 m) and ranged in size from 8.5 cm to 13.3 cm. Three prey groups were identified in the stomachs (euphausiids, amphipods, and fish (Maurolicus muelleri and Lampanyctodes hectoris)). When grouped into two size groups (larger and smaller than 10.0 cm) there was a tendency of more fish prey and less cructacean prey in the diet of the larger size group compared to the smaller size group. However, both fish prey and cructacean prey were found in stomachs of both size groups and even the smallest M. paradoxus (8.5 cm) had a M. muelleri in the stomach showing that they are piscivorous even at that small size. Based on the material preserved during the survey, further analyses of gut content will be done in order to better quantify the importance of different prey groups for juvenile M. paradoxus. 12

Length distributions of M. paradoxus juveniles caught at the repeat station in the Multisampler during night time in the layers near-bottom (left), mid-water (middle) and nearsurface (right). 5 Conclusions Since no juvenile M. paradoxus smaller than 5 cm were caught during the survey while relatively high concentrations of juveniles (6-20 cm) were found, it is reasonable to assume that the juveniles at this time of the year already had passed the phase were they are entirely pelagic. Juvenile M. paradoxus in the size range 6-20 cm performed vertical migration, being demersal during daytime and lifting up from the bottom at night. The smaller juveniles (6-10 cm) perform the most extensive vertical migrations, from being demersal (200 m depth) during daytime to the being in the upper 40 m during night time. Gut analysis showed that the juveniles migrated towards the surface at night most likely in order to follow the vertical migration of prey species consisting of euphausiids, amphipods, M. muelleri and L. hectoris. 16
